'''U.S. Route&nbsp;6''' ('''US&nbsp;6''') or '''U.S. Highway&nbsp;6''' ('''US&nbsp;6'''), also called the '''Grand Army of the Republic Highway''', honoring the [[Grand Army of the Republic|American Civil War veterans association]], is a main route of the [[United States Numbered Highway System]]. While it currently runs east-northeast from [[Bishop, California]], to [[Provincetown, Massachusetts]], the route has been modified several times. The highway's longest-lasting routing, from 1936 to 1964, had its western terminus at [[Long Beach, California]]. During this time, US&nbsp;6 was the longest highway in the country.

In 1964, the state of California [[1964 state highway renumbering (California)|renumbered its highways]], and most of the route within California was transferred to other highways. This dropped the highway's length below that of [[U.S. Route 20|US&nbsp;20]], making it the second-longest U.S. Route in the country. However, since US&nbsp;20 has a discontinuity through [[Yellowstone National Park]], US&nbsp;6 remains the longest continuous U.S. Route in the country.

US&nbsp;6 is a diagonal route, whose number is out of sequence with the rest of the U.S. Route grid in the [[Western U.S.]] When it was designated in 1926, US&nbsp;6 only ran east of [[Erie, Pennsylvania]]. Subsequent extensions, largely replacing the former [[U.S. Route 32]] and '''U.S. Route&nbsp;38''' ('''US&nbsp;38'''), have taken it south of [[U.S. Route 30|US&nbsp;30]] at [[Joliet, Illinois]], [[U.S. Route 40|US&nbsp;40]] near [[Denver|Denver, Colorado]] (past the end of US&nbsp;38), [[U.S. Route 50|US&nbsp;50]] at [[Ely, Nevada]], and [[U.S. Route 70|US&nbsp;70]] near [[Los Angeles|Los Angeles, California]], due to its north–south alignment in that state.

US&nbsp;6 does not serve a major transcontinental corridor, unlike other highways. [[George R. Stewart]], author of ''U.S.&nbsp;40: Cross Section of the United States of America'', initially considered US&nbsp;6, but realized that "Route&nbsp;6 runs uncertainly from nowhere to nowhere, scarcely to be followed from one end to the other, except by some devoted eccentric".

[[File:P-town.jpg|thumb|Heading east from Bishop, California]]

The modern US&nbsp;6 in [[California]] is a short, two-lane, north–south surface highway from [[Bishop, California|Bishop]] to the [[Nevada]] state line. Prior to the [[1964 state highway renumbering (California)|1964 state highway renumbering]], US&nbsp;6 extended to [[Long Beach, California|Long Beach]] along what is now [[U.S. Route 395|US&nbsp;395]], [[California State Route 14|State Route&nbsp;14]] (SR&nbsp;14), [[Interstate 5]] (I-5), [[Interstate 110 and State Route 110 (California)|I-110/SR&nbsp;110]], and [[California State Route 1|SR&nbsp;1]]. Despite the fact that the renumbering removed all freeway portions, it is still part of the [[California Freeway and Expressway System]]. US&nbsp;6's former routing included a short segment of the famous [[Arroyo Seco Parkway]].

Currently, US&nbsp;6 begins at US&nbsp;395 in Bishop and heads north between farms and ranches in [[Chalfant, California|Chalfant]] at the base of the {{convert|14000|ft|m|adj=on}} western [[escarpment]] of the [[White Mountains (California)|White Mountains]]. After about {{convert|30|mi|km}}, [[Benton, California|Benton]] is reached, which has a cafe and gas station. [[California State Route 120|SR&nbsp;120]] begins here, heading west past [[Mono Lake]] through [[Lee Vining, California|Lee Vining]], over [[Tioga Pass]], and through [[Yosemite National Park]] to the [[San Joaquin Valley]]. US&nbsp;6 continues north to the Nevada state line.

===Nevada===
{{main|U.S. Route 6 in Nevada}}
[[File:2013-07-14 08 29 37 View east along U.S. Routes 6 and 50 at the junction with U.S. Route 93 in Majors Place, Nevada.jpg|thumb|US&nbsp;6 and US&nbsp;50 east of the intersection with US&nbsp;93]]
From the California state line, US&nbsp;6 heads northeast through the semidesert Queen Valley with [[Boundary Peak (Nevada)|Boundary Peak]], Nevada's highest summit, and [[Montgomery Peak]] in California on the right. These twin peaks are the northernmost high summits of the [[White Mountains (California)|White Mountains]], both over {{convert|13000|ft|m}}. The highway then climbs into [[pinyon–juniper woodland]] and crosses Montgomery Pass ({{convert|7167|ft|m|abbr=on|disp=or}}).

From the pass, US&nbsp;6 descends into barren [[Atriplex confertifolia|shadscale]] desert, passing [[Columbus Marsh]] on the left, then merging with [[U.S. Route 95|US&nbsp;95]] from Coaldale Junction to [[Tonopah, Nevada|Tonopah]]. The [[Nevada Test and Training Range]] begins about {{convert|15|mi|km}} southeast of Tonopah.

Just east of Tonopah, US&nbsp;6 continues east across a series of [[Basin and Range Province|desert mountain ranges and valleys]], including the [[Monitor Range]]. At [[Warm Springs, Nevada|Warm Springs]], [[Nevada State Route 375|SR&nbsp;375]], also known as the "Extraterrestrial Highway", departs to the southeast and US&nbsp;6 assumes a northeasterly alignment across the [[Reveille Range|Reveille]], [[Pancake Range|Pancake]], [[Grant Range|Grant]] and [[White Pine Range|White Pine]] ranges. Rainfall increases eastward, so valleys become less barren and peaks over {{convert|11500|ft|m}} add scenic interest.

[[Ely, Nevada|Ely]] is the largest city on US&nbsp;6 in Nevada. [[U.S. Route 50|US&nbsp;50]] joins US&nbsp;6 at Ely. East of Ely, US&nbsp;6/US&nbsp;50 cross the [[Schell Creek Range]], known for verdant forests and meadows and for a large [[mule deer]] and [[elk]] population. The highway descends to [[Spring Valley (White Pine County, Nevada)|Spring Valley]], then crosses the [[Snake Range]] at Sacramento Pass, north of Nevada's second-highest mountain, [[Wheeler Peak (Nevada)|Wheeler Peak]], where a branch road accesses [[Great Basin National Park]]. Beyond the pass, US&nbsp;6 passes just north of [[Baker, Nevada|Baker]], a [[Mormon]] farming community, and reaches the [[Utah]] state line.

===Utah===
{{main|U.S. Route 6 in Utah}}
US&nbsp;6 enters Utah [[Concurrency (road)|concurrently]] with US&nbsp;50 in a remote portion of the [[Great Basin Desert]]; the routes separate at [[Delta, Utah|Delta]]. US&nbsp;6 then proceeds on a northeast course toward the [[Wasatch Front]] serving the [[East Tintic Mountains|Tintic]] and [[Eureka, Utah|Eureka]] historic and mining districts along the way. Upon entering the Wasatch Front, at [[Santaquin, Utah|Santaquin]], the route joins [[Interstate 15|I-15]] to [[Spanish Fork, Utah|Spanish Fork]], which is where US&nbsp;6 reverses course on a southeastern path away from the Wasatch front, also joining with [[U.S. Route 89|US&nbsp;89]] for the journey through [[Spanish Fork (river)|Spanish Fork]] canyon. After cresting the [[Wasatch Range]] via [[Soldier Summit, Utah|Soldier Summit]], the route descends into Utah's coal country, which is where it joins [[U.S. Route 191|US&nbsp;191]]. At [[Green River, Utah|Green River]], those two routes join [[Interstate 70|I-70]] and rejoin US&nbsp;50. From Green River east the routes travel concurrently using the route of I-70 following the southern rim of the [[Book Cliffs]]. US&nbsp;191 leaves the concurrency at Crescent Junction but the other three routes remain concurrent as they continue to follow the Book Cliffs toward the [[Grand Valley (Colorado–Utah)|Grand Valley]] into Colorado.

===Colorado===
{{main|U.S. Route 6 in Colorado}}
[[File:6408-LovelandPassCOLO.jpg|thumb|Loveland Pass in 1964]]
US&nbsp;6 is basically parallel to, or runs concurrently with, [[Interstate 70|I-70]] for a significant portion of its length as it generally heads east from the Utah state line through about half of [[Denver]]. It is unsigned while it is overlapped. It separates to become [[Interstate 70 Business (Grand Junction–Clifton, Colorado)|I-70 Business]] (I-70 Bus.) through the south side of [[Grand Junction, Colorado|Grand Junction]], rejoining I-70 just east of Palisade. It again separates west of [[Rifle, Colorado|Rifle]] and runs through [[Antlers, Colorado|Antlers]], [[Silt, Colorado|Silt]], [[New Castle, Colorado|New Castle]], and [[Chacra, Colorado|Chacra]] until it again joins I-70. It separates from and runs parallel to, I-70 at [[Dotsero, Colorado|Dotsero]], where the [[Eagle River (Colorado)|Eagle River]] joins the [[Colorado River]]. It again joins I-70 just east of [[Avon, Colorado|Avon]], the location of the [[Beaver Creek Resort]], just a bit west of [[Vail, Colorado|Vail]]. A significant departure from I-70 occurs at [[Silverthorne, Colorado|Silverthorne]] where it veers a bit south then north, avoiding the nearly {{convert|2|mi|km|adj=mid|-long|spell=in}} tunnel on I-70 as it goes under the [[Continental Divide of the Americas|Continental Divide]]. It passes [[Keystone Resort]] and [[Arapahoe Basin]] before a steep climb to the highest altitude along US&nbsp;6, {{convert|11990|ft|m}}, at [[Loveland Pass]], where it crosses the Continental Divide. It continues down the [[Clear Creek (Colorado)|Clear Creek]] valley as it again reaches I-70 at the [[Loveland Ski Area]] straddling the eastern mouth of the [[Eisenhower Tunnel]]. Slightly east of [[Idaho Springs, Colorado|Idaho Springs]], it separates to go through the scenic [[Clear Creek Canyon]]. At [[Golden, Colorado|Golden]], it combines with 6th Avenue to head south until it again crosses paths with I-70. Then, continuing east, it passes through [[Lakewood, Colorado|Lakewood]] and west Denver as the 6th Avenue freeway. From near the eastern terminus of the 6th Avenue freeway, US&nbsp;6 takes a convoluted route through Denver. First, it turns north on [[Interstate 25|I-25]], then heads east on I-70 to Vasquez Boulevard through [[Elyria-Swansea, Denver|Elyria-Swansea]]. The route emerges from the freeway alongside US&nbsp;85 through [[Commerce City, Colorado|Commerce City]], where the pair briefly join [[Colorado State Highway 2|State Highway&nbsp;2]] (SH&nbsp;2) before separating at Colorado Boulevard. SH&nbsp;2 represents the historic alignment of US&nbsp;6 northeast to [[Brighton, Colorado|Brighton]], while US&nbsp;6 combines with I-76, heading northeast, until east of [[Brush, Colorado|Brush]]. It then separates to join [[Interstate 76 Business (Fort Morgan–Sterling, Colorado)|I-76 Bus.]] until it crosses I-76 east of [[Sterling, Colorado|Sterling]], where it changes direction from the Interstate. It continues east until it reaches [[Nebraska]]. The last town in Colorado that it passes is [[Holyoke, Colorado|Holyoke]].

===Nebraska===
{{main|U.S. Route 6 in Nebraska}}
From the Colorado state line, US&nbsp;6 starts going southeast. The first town it goes into is [[Imperial, Nebraska|Imperial]]. US&nbsp;6 runs concurrently with [[U.S. Route 34|US&nbsp;34]] near [[Culbertson, Nebraska|Culbertson]], passing through [[McCook, Nebraska|McCook]]. US&nbsp;6 then moves to the northeast, through [[Hastings, Nebraska|Hastings]]. At Hastings, US&nbsp;34 diverges and moves north. US&nbsp;6 parallels [[Interstate 80|I-80]] north of [[Milford, Nebraska|Milford]] until it reaches [[Lincoln, Nebraska|Lincoln]]. At Lincoln, US&nbsp;6 becomes West "O" Street, Sun Valley Boulevard, and eventually [[Cornhusker Highway]] as it moves north of I-80 outside of the city, paralleling I-80 to [[Gretna, Nebraska|Gretna]]. There US&nbsp;6 moves due north and becomes the West Dodge Expressway and [[Dodge Street]] in [[Omaha, Nebraska|Omaha]]. It passes through [[Downtown Omaha]] on [[One-way pair|parallel one-way streets]] and runs concurrently with [[Interstate 480 (Nebraska–Iowa)|I-480]] in Omaha on its last Nebraska segment. East of Omaha, it crosses the [[Missouri River]] to enter [[Iowa]] at [[Council Bluffs, Iowa]], on a girder bridge completed in 1966 that replaced the [[Ak-Sar-Ben Bridge]], which was the first road bridge to connect the two cities.

===Iowa===
{{main|U.S. Route 6 in Iowa}}
[[File:US&nbsp;6 east of Newton.jpg|thumb|US&nbsp;6 east of Newton, Iowa]]
From the Nebraska state line, US&nbsp;6 enters [[Iowa]] at [[Council Bluffs, Iowa|Council Bluffs]], across the Missouri River from Omaha where it intersects [[Interstate 29|I‑29]] within the first mile. Through Council Bluffs, it travels south concurrent with I‑29, then turns east to run concurrent with I‑29 and [[Interstate 80|I‑80]]. Where I-29 and I-80 split, US&nbsp;6 continues northeast concurrent with I-80. The concurrency with I-80 ends at the interchange with East Kanesville Boulevard, on the northeast side of Council Bluffs, at which point US&nbsp;6 turns east to run through rural [[Pottawattamie County, Iowa|Pottawattamie County]]. Further east, the highway briefly overlaps [[U.S. Route 59|US&nbsp;59]] near [[Oakland, Iowa|Oakland]] and continues east until [[Lewis, Iowa|Lewis]]. There, it turns sharply north-northeast to [[Atlantic, Iowa|Atlantic]] where joins [[U.S. Route 71|US&nbsp;71]] until I‑80. It overlaps I‑80 between US&nbsp;71 and [[U.S. Route 169|US&nbsp;169]] at [[De Soto, Iowa|De Soto]]. US&nbsp;6 travels north with US&nbsp;169 to [[Adel, Iowa|Adel]], then turns east to go toward [[Des Moines, Iowa|Des Moines]]. It enters the Des Moines metro area along Hickman Road in [[Waukee, Iowa|Waukee]] and then forms the border between [[Urbandale, Iowa|Urbandale]] to the north and [[Clive, Iowa|Clive]] and [[Windsor Heights, Iowa|Windsor Heights]] to the south. In Des Moines, [[Iowa Highway 28]] (Iowa&nbsp;28) joins US&nbsp;6 at 63rd Street, and the two highways head east and north on Merle Hay Road. US&nbsp;6 splits away at Douglas Avenue and it continues east. Near the [[Des Moines River]], Douglas Avenue becomes Euclid Avenue. In the northeastern part of the city, it intersects [[U.S. Route 69|US&nbsp;69]] and [[Interstate 235 (Iowa)|I‑235]]. The highway turns onto Hubbell Avenue and heads into [[Altoona, Iowa|Altoona]] where it meets [[U.S. Route 65|US&nbsp;65]] and rejoins I‑80.<ref name=IowaDOT>{{Cite IowaDOT map|access-date=March 1, 2014|year=2012}}</ref>

East of the [[Des Moines metropolitan area]], US&nbsp;6 again overlaps I‑80 until they reach [[Newton, Iowa|Newton]]. There, it splits away to the north and runs parallel to the Interstate. It passes through [[Grinnell, Iowa|Grinnell]], [[Marengo, Iowa|Marengo]], and the [[Amana Colonies]] before arriving in [[Coralville, Iowa|Coralville]]. In [[Iowa City, Iowa|Iowa City]], it passes through the [[University of Iowa]] campus on the banks of the [[Iowa River]]. The highway heads southeast from Iowa City toward [[West Liberty, Iowa|West Liberty]] and then more easterly to [[Wilton, Iowa|Wilton]]. At Wilton, the highway heads north to rejoin I‑80 until they reach [[Davenport, Iowa|Davenport]]. After a short overlapping of [[Interstate 280 (Iowa–Illinois)|I‑280]], US&nbsp;6 enters the city along Kimberly Road, on which it remains until [[Interstate 74|I‑74]]. The two routes then run south to cross the [[Mississippi River]] into Illinois on the [[I-74 Bridge]].<ref name=IowaDOT/>

===Illinois===
{{main|U.S. Route 6 in Illinois}}
{{See also|159th Street (Chicago)|Torrence Avenue|Kingery Expressway}}
In [[Illinois]], US&nbsp;6 parallels [[Interstate 74|I-74]] and I-80, mostly along its original routing, overlapping with I-74 for its first {{convert|5|mi|km|spell=in}} and I-80 for the final {{convert|2|mi|km|spell=in}} of its routing in Illinois. US&nbsp;6 directly serves the downtowns of many cities for its length, including [[Oak Forest, Illinois|Oak Forest]], [[Tinley Park, Illinois|Tinley Park]], [[Moline, Illinois|Moline]], [[Geneseo, Illinois|Geneseo]], [[Atkinson, Illinois|Atkinson]], [[Annawan, Illinois|Annawan]], [[Princeton, Illinois|Princeton]], [[Peru, Illinois|Peru]], [[La Salle, Illinois|La Salle]], [[Ottawa, Illinois|Ottawa]], [[Channahon, Illinois|Channahon]], and [[Joliet, Illinois|Joliet]]—unlike [[U.S. Route 20|US&nbsp;20]], which, in Illinois, mainly consists of freeway sections that bypass the cities US&nbsp;6 serves. Like nearby [[U.S. Route 30|US&nbsp;30]] and [[U.S. Route 52|US&nbsp;52]], US&nbsp;6 skirts the [[Chicago]] city limits.

=== Indiana ===
{{main|U.S. Route 6 in Indiana}}
US&nbsp;6 crosses the state line and shares the same [[Borman Expressway]] with [[Interstate 80|I-80]] and [[Interstate 94|I-94]] through [[Hammond, Indiana|Hammond]] and [[Gary, Indiana|Gary]], until [[Indiana State Road 51|State Road&nbsp;51]] (SR&nbsp;51, exit&nbsp;15); it then runs south for about {{convert|2|mi|km|spell=in}} and turns east until it meets [[U.S. Route 421|US&nbsp;421]] in [[Westville, Indiana|Westville]], then runs south for {{One2a|{{convert|1|mi|km|spell=in}}}}, then east until it meets [[U.S. Route 31|US&nbsp;31]] and [[U.S. Route 35|US&nbsp;35]], and it shares the same road with [[U.S. Route 33|US&nbsp;33]] for about {{convert|5|mi|km|spell=in}} until [[Ligonier, Indiana|Ligonier]], where US&nbsp;33 breaks south toward [[Fort Wayne, Indiana|Fort Wayne]]. From there, it is mostly two lanes through Indiana until it meets the Ohio state line just east of [[Butler, Indiana|Butler]]. Before the Borman Expressway was completed, US&nbsp;6 was on Ridge Road, portions of which were signed [[U.S. Route 6 Business (Lansing, Illinois–Lake Station, Indiana)|US&nbsp;6 Bus.]]

===Ohio===
{{main|U.S. Route 6 in Ohio}}
[[File:Detroit-Superior Bridge2.jpg|thumb|The Detroit–Superior Bridge in Cleveland]]
US&nbsp;6 enters [[Ohio]] from Indiana in [[Williams County, Ohio|Williams County]]. It travels through [[Edgerton, Ohio|Edgerton]], then just south of [[Bryan, Ohio|Bryan]] before it passes through [[Napoleon, Ohio|Napoleon]], [[Bowling Green, Ohio|Bowling Green]], and [[Fremont, Ohio|Fremont]], before turning northeast toward [[Sandusky Bay]] and [[Lake Erie]]. After passing through [[Sandusky, Ohio|Sandusky]], the highway follows the southern shore of Lake Erie, passing through [[Huron, Ohio|Huron]] and [[Vermilion, Ohio|Vermilion]]. After crossing the [[Charles Berry Bridge]] in [[Lorain, Ohio|Lorain]], it passes through the western suburbs of [[Greater Cleveland]] as Lake Road in [[Sheffield Lake, Ohio|Sheffield Lake]], [[Avon Lake, Ohio|Avon Lake]], [[Bay Village, Ohio|Bay Village]], and [[Rocky River, Ohio|Rocky River]], and Clifton Boulevard in [[Lakewood, Ohio|Lakewood]] and the [[West Boulevard]]–[[Edgewater, Cleveland|Edgewater]] neighborhood of [[Cleveland]] proper. US&nbsp;6 follows the [[Cleveland Memorial Shoreway]] into [[Downtown Cleveland]], entering downtown by crossing the [[Detroit–Superior Bridge]]. US&nbsp;6 follows Superior Avenue through [[Public Square, Cleveland|Public Square]] and the east side of Cleveland before turning east onto [[Euclid Avenue (Cleveland)|Euclid Avenue]] in [[East Cleveland, Ohio|East Cleveland]] and Chardon Road in the city of [[Euclid, Ohio|Euclid]]. US&nbsp;6 continues eastward through [[Lake County, Ohio|Lake County]], [[Geauga County, Ohio|Geauga County]], and finally into [[Ashtabula County, Ohio|Ashtabula County]] before entering the state of [[Pennsylvania]] along the [[Pymatuning Reservoir]] causeway.

Ohio also has an [[U.S. Route 6 Alternate (Rocky River–Cleveland, Ohio)|alternate route of US&nbsp;6]] in [[Greater Cleveland]].

===Pennsylvania===
{{main|U.S. Route 6 in Pennsylvania}}
[[File:Ansonia, pennsylvania, skyline.jpg|thumb|US&nbsp;6 in [[Ansonia, Pennsylvania]], near [[Tioga State Forest]]]]
US&nbsp;6 runs for {{convert|403|mi|km}} in [[Pennsylvania]] between its entrance point {{convert|20|mi|km}} west of [[Meadville, Pennsylvania|Meadville]] and its exit at [[Matamoras, Pennsylvania|Matamoras]]. From the Ohio border to [[U.S. Route 322|US&nbsp;322]] in [[Conneaut Lake, Pennsylvania|Conneaut Lake]], the route runs in a southeasterly direction. US&nbsp;6 then joins US&nbsp;322 and heads east to Meadville, picking up [[U.S. Route 19|US&nbsp;19]] west of the city. South of downtown, US&nbsp;322 splits from the concurrency while US&nbsp;6 and US&nbsp;19 remain concurrent through Meadville. The two routes continue northward to [[Mill Village, Pennsylvania|Mill Village]], where US&nbsp;6 and US&nbsp;19 split at a junction with [[U.S. Route 6N|US&nbsp;6N]].

For the remainder of its routing in Pennsylvania, US&nbsp;6 runs roughly parallel to the [[New York–Pennsylvania border]]. Along the way, US&nbsp;6 is concurrent with [[U.S. Route 62|US&nbsp;62]] for a short distance near [[Warren, Pennsylvania|Warren]]. [[U.S. Route 11|US&nbsp;11]] joins US&nbsp;6 from the north in [[Factoryville, Pennsylvania|Factoryville]]. They run concurrently to [[Scranton, Pennsylvania|Scranton]], where US&nbsp;11 continues south and US&nbsp;6 east. At [[Milford, Pennsylvania|Milford]], US&nbsp;6 meets [[U.S. Route 209|US&nbsp;209]]. The two routes embark to the northeast, crossing the [[Delaware River]] from [[Matamoras, Pennsylvania|Matamoras]] to [[Port Jervis, New York]].

===New York===
{{main|U.S. Route 6 in New York}}
[[Image:US&nbsp;6 in Harriman State Park.jpg|thumb|US&nbsp;6 climbing into the [[Hudson Highlands]] in [[Harriman State Park (New York)|Harriman State Park]] on the west bank of the [[Hudson River]] in southern New York]]
The {{convert|79|mi|km|adj=on}} portion of US&nbsp;6 in [[New York (state)|New York]] travels through [[Orange County, New York|Orange]], [[Putnam County, New York|Putnam]], and [[Westchester County, New York|Westchester]] counties, going across the southern part of the state through the northern suburbs of [[New York City]]. The route enters the state along with US&nbsp;209 in [[Port Jervis, New York|Port Jervis]]. The two routes split just north of town, with US&nbsp;209 taking a more northerly route to access [[Kingston, New York|Kingston]]. US&nbsp;6, in contrast, runs primarily east–west through southern New York.

A section of US&nbsp;6 runs concurrent with [[New York State Route&nbsp;17]] (NY&nbsp;17; The Quickway) between [[Goshen (village), New York|Goshen]] and [[Harriman, New York|Harriman]]. The route is currently being upgraded to become part of [[Interstate 86 (Pennsylvania–New York)|I-86]]. At Harriman, US&nbsp;6 passes through one of the largest interchanges in the state of New York, where US&nbsp;6/NY&nbsp;17 meet [[Interstate 87 (New York)|I-87]] ([[New York State Thruway]]) and [[New York State Route 32|NY&nbsp;32]]. NY&nbsp;17 becomes an at-grade road and heads south, while US&nbsp;6 remains a limited-access freeway as it heads east into [[Harriman State Park (New York)|Harriman State Park]]. Near the east side of the park, US&nbsp;6 intersects the [[Palisades Interstate Parkway]] and runs concurrently with it to the historic [[Bear Mountain Bridge]], where US&nbsp;6 is joined by [[U.S. Route 202|US&nbsp;202]] and is narrowed to a rural two-lane road as it crosses the [[Hudson River]] with scenic views of the [[Hudson Highlands]].

On the other side of the river and exiting Orange County for Westchester, US&nbsp;6 and US&nbsp;202 run along the Hudson River to [[Peekskill, New York|Peekskill]] and has a short concurrency with [[U.S. Route 9|US&nbsp;9]] before the three routes split, allowing US&nbsp;6 to continue to the northeast through northern Westchester County and into Putnam County. At Shrub Oak, US&nbsp;6 has an interchange with the historic [[Taconic State Parkway]], one of the first and most scenic long-distance freeways in the U.S. In [[Brewster, New York|Brewster]], US&nbsp;6 joins US&nbsp;202 once again, with the routes running concurrently into [[Connecticut]]. US&nbsp;6 and US&nbsp;202 also have a large interchange with [[Interstate 84 (Pennsylvania–Massachusetts)|I-84]], [[Interstate 684|I-684]], and [[New York State Route 22|NY&nbsp;22]] in Brewster.

===Connecticut===
{{main|U.S. Route 6 in Connecticut}}
US&nbsp;6 runs for {{convert|116.3|mi|km}} in Connecticut. It enters from the town of [[Southeast, New York]], concurrent with [[U.S. Route 202|US&nbsp;202]], shortly passes through begins the city of [[Danbury, Connecticut|Danbury]], and ends at the Rhode Island state line in the town of [[Killingly, Connecticut|Killingly]]. In western Connecticut, US&nbsp;6 either closely parallels or is concurrent with [[Interstate 84 (Pennsylvania–Massachusetts)|I-84]], serving as the local route in the suburbs of Danbury, [[Waterbury, Connecticut|Waterbury]], [[Bristol, Connecticut|Bristol]], and [[Hartford, Connecticut|Hartford]]. It crosses the [[Connecticut River]] (overlapped with I-84 and [[U.S. Route 44|US&nbsp;44]]) on the [[Bulkeley Bridge]]. In eastern Connecticut, US&nbsp;6 is one of the principal routes connecting Hartford and [[Providence, Rhode Island|Providence]], passing through the small urban areas of [[Willimantic, Connecticut|Willimantic]] and [[Danielson, Connecticut|Danielson]]. The unsigned portion of the [[Connecticut Turnpike]] then meets with US&nbsp;6 shortly before crossing the [[Rhode Island]] state line.

===Rhode Island===
{{main|U.S. Route 6 in Rhode Island}}

US&nbsp;6 covers approximately {{convert|26.5|mi|km}} in Rhode Island from [[Foster, Rhode Island|Foster]] (western border with [[Killingly, Connecticut]]) to [[East Providence, Rhode Island|East Providence]] (eastern border with [[Seekonk, Massachusetts]]). In and around [[Providence, Rhode Island|Providence]], US&nbsp;6 overlaps with [[Rhode Island Route 10|Route&nbsp;10]], as well as [[U.S. Route 1A (Rhode Island)|US&nbsp;1A]], [[U.S. Route 44|US&nbsp;44]], [[Interstate 95|I-95]], [[Interstate 195 (Rhode Island–Massachusetts)|I-195]], and [[Interstate 295 (Rhode Island–Massachusetts)|I-295]].

US&nbsp;6 runs approximately {{convert|117.5|mi|km}} in [[Massachusetts]], paralleling I-195 between Providence and [[Wareham, Massachusetts|Wareham]], and serves as the local business route. US&nbsp;6 continues onto [[Cape Cod]] across the [[Sagamore Bridge]] as a [[freeway]] from [[Bourne, Massachusetts|Bourne]] to [[Orleans, Massachusetts|Orleans]]. North of Orleans, it becomes a surface road again to its terminus in [[Provincetown, Massachusetts|Provincetown]]. Although the westbound sign in Provincetown has been updated to reflect the shorter terminus in [[Bishop, California]], the eastbound sign in Provincetown still reflects the original coast-to-coast terminus of [[Long Beach, California]] (see photo).

==History==
===New England===
[[Image:New England 3.svg|left|75px]]
The first interstate numbering along the path of US&nbsp;6 was [[New England road marking system#Route 3|Route&nbsp;3]] of the [[New England road marking system]], designated in 1922. This route connected [[Provincetown, Massachusetts|Provincetown]] with the New York–Connecticut border via [[Providence, Rhode Island|Providence]], [[Hartford, Connecticut|Hartford]], and [[Danbury, Connecticut|Danbury]].<ref name="1926 National Survey">[[National Survey Company]], The official National Survey maps and guide for Southern New England: Massachusetts, Connecticut, Rhode Island, 1926, accessed via the [http://www.broermapsonline.org/members/ Broer Map Library]{{full citation needed|date=December 2021}}</ref><ref name="1926 Rand McNally">[[Rand McNally]] Auto Road Atlas, 1926, accessed via the [http://www.broermapsonline.org/members/ Broer Map Library]{{full citation needed|date=December 2021}}</ref> In late 1925, the [[Joint Board on Interstate Highways]] approved the preliminary plan for U.S. Routes. US&nbsp;6 was restricted to [[New England]] and southeastern [[New York (state)|New York]], with its vague description matching the existing Route&nbsp;3 to [[Danbury, Connecticut]], and heading west from there to [[U.S. Route 7|US&nbsp;7]] at [[Brewster, New York]].<ref name="1925 list">{{cite book |type= Report |author = Joint Board on Interstate Highways |year = 1925 |chapter = Appendix VI: Descriptions of the Interstate Routes Selected, with Numbers Assigned |chapter-url = https://en.wikisource.org/wiki/Report_of_Joint_Board_on_Interstate_Highways_October_30,_1925#49 |title = Report of Joint Board on Interstate Highways, October 30, 1925, Approved by the Secretary of Agriculture, November 18, 1925 |location= Washington, DC |publisher= [[United States Department of Agriculture]]  |page = 49|id= {{OCLC|733875457|55123355|71026428}} |via = [[Wikisource]] |access-date = November 14, 2017 }}</ref> By the time the final plan was approved in late 1926, a second section had been added, from the [[New York–Pennsylvania border]] at [[Port Jervis, New York]], west to [[U.S. Route 120|US&nbsp;120]] in [[Kane, Pennsylvania]].<ref name="1926 map">{{cite map |author1= Bureau of Public Roads |author-link= Bureau of Public Roads |author2= American Association of State Highway Officials |author2-link= American Association of State Highway Officials |name-list-style= amp |date= November 11, 1926 |title= United States System of Highways Adopted for Uniform Marking by the American Association of State Highway Officials |url= https://commons.wikimedia.org/wiki/File:United_States_System_of_Highways_Adopted_for_Uniform_Marking_by_the_American_Association_of_State_Highway_Officials.jpg |scale= 1:7,000,000 |location= Washington, DC |publisher= [[United States Geological Survey]] |oclc= 32889555 |access-date= November 7, 2013 |via= [[Wikimedia Commons]] }}</ref> This did not last long, for the April 1927 route log shows the eastern segment running only to the border of New York, short of Brewster, while the western segment was extended in both directions—east to [[Kingston, New York]], and west to [[Erie, Pennsylvania]] (the latter replacing part of US&nbsp;120). The western segment was also swapped with [[U.S. Route 106|US&nbsp;106]] between [[Carbondale, Pennsylvania|Carbondale]] and [[Tunkhannock, Pennsylvania|Tunkhannock]], Pennsylvania, taking US&nbsp;6 through [[Scranton, Pennsylvania|Scranton]].<ref name="1927 log">{{cite magazine |title = United States Numbered Highways |magazine = [[American Highways]] |publisher = [[American Association of State Highway Officials]] |date = April 1927 }}</ref> The gap through New York was eliminated in 1928 with a new alignment across the state, crossing the [[Hudson River]] on the [[Bear Mountain Bridge]]; the old route between Kingston and Port Jervis became the first [[U.S. Route 6N (New York)|US&nbsp;6N]].<ref name=FHWA>{{cite web |first = Richard F. |last = Weingroff |url = https://www.fhwa.dot.gov/infrastructure/us6.cfm |title = U.S.&nbsp;6: The Grand Army of the Republic Highway |work = Highway History |publisher = [[Federal Highway Administration]] }}</ref>

While US&nbsp;6 replaced the general corridor of Route&nbsp;3 in New England, some portions used different alignments. One of these was on [[Cape Cod]], where Route&nbsp;3 had used a southerly alignment that is now [[Massachusetts Route 28|Route&nbsp;28]]. Instead, US&nbsp;6 followed the more direct route between [[Buzzards Bay, Massachusetts|Buzzards Bay]] and [[Orleans, Massachusetts|Orleans]] that had been the southern extremity of [[New England Route 6|Route&nbsp;6]], and now known as [[Massachusetts Route 6A|Route&nbsp;6A]]. Farther west, in Connecticut, US&nbsp;6 ran via the [[South Coventry Historic District]], while Route&nbsp;3 had served [[Andover, Connecticut|Andover]]; the old route became [[U.S. Route 6A (Andover, Connecticut)|US&nbsp;6A]].{{Citation needed|date=July 2007}} US&nbsp;6 is now on the old Route&nbsp;3, while the South Coventry route now carries [[Connecticut Route 31|Route&nbsp;31]]. A different alignment was also chosen for US&nbsp;6 between [[Plainville, Connecticut|Plainville]] and [[Woodbury, Connecticut|Woodbury]]; Route&nbsp;3 ran via [[Milldale (Southington)|Milldale]] and [[Waterbury, Connecticut|Waterbury]], and became parts of [[Connecticut Route 14|Route&nbsp;14]] and [[Connecticut Route 10|Route&nbsp;10]] in the [[1932 state highway renumbering (Connecticut)|1932 state highway renumbering]].<ref>[[Connecticut State Highway Department]], [http://www.kurumi.com/roads/ct/1920s.html state map], 1932{{full citation needed|date=December 2021}}</ref> Here, US&nbsp;6 mostly remains on its original routing, with the main difference being between [[Hartford, Connecticut|Hartford]] and [[Terryville, Connecticut|Terryville]], where US&nbsp;6 followed the present [[Connecticut Route 4|Route&nbsp;4]], Route&nbsp;10, and [[Connecticut Route 72|Route&nbsp;72]]. The final difference was from [[Danbury, Connecticut|Danbury]] west to the New York state line; here, US&nbsp;6 ran straight west, while Route&nbsp;3 had left the Danbury area to the south, curving to the southwest through [[Ridgefield, Connecticut|Ridgefield]] to the border.

Two other routes that would become part of US&nbsp;6 were included in the 1925 plan: US&nbsp;32 from [[Chicago|Chicago, Illinois]] to [[Omaha, Nebraska]], and US&nbsp;38 from [[Lincoln, Nebraska]] to [[Greeley, Colorado]].<ref name="1925 list" /> As part of the fine-tuning during 1926, US&nbsp;38 was extended east from Lincoln to Omaha, allowing [[U.S. Route 77|US&nbsp;77]], which had been assigned to this road, to extend north to [[Sioux City, Iowa]]. These routes, which now connected end-to-end at Omaha, replaced a large portion of the [[Detroit–Lincoln–Denver Highway]], which split at [[Princeton, Illinois|Princeton]] to bypass Chicago to the south via [[Joliet, Illinois|Joliet]]. They followed existing state highways: [[Colorado State Highway 2|SH&nbsp;2]] and [[Colorado State Highway 14|SH&nbsp;14]] in Colorado, [[Nebraska Highway 7]] in Nebraska, [[Iowa Highway 2|Iowa&nbsp;2]] and [[Iowa Highway 7|Iowa&nbsp;7]] in Iowa, and [[Illinois Route 7]] (IL&nbsp;7) and [[Illinois Route 18|IL&nbsp;18]] in Illinois.<ref name="1926 Rand McNally" /><ref name="1926 map" />

Most of US&nbsp;32 and all of US&nbsp;38 became a western extension of US&nbsp;6 on June 8, 1931, and the Roosevelt Highway name followed.<ref>{{cite news |work = [[McKean County Democrat]] |title = Roosevelt Highway Route is Extended to Colorado |date = June 18, 1931 }}</ref> To connect [[Western Pennsylvania]] to [[Central Indiana]], relatively minor roads<ref name="1926 Rand McNally" /> (including the route for SR&nbsp;6 in Indiana) were used, except west of Joliet, where it used a part of the old Detroit–Lincoln–Denver Highway. The short stub to [[Erie, Pennsylvania]], formed at the old west end became [[U.S. Route 6N|US&nbsp;6N]], and US&nbsp;32 remained in Illinois, running independently from Chicago to Princeton and [[Concurrency (road)|overlapping]] US&nbsp;6 to [[Davenport, Iowa]].<ref name="FHWA" /> In 1934, US&nbsp;32 was absorbed into [[U.S. Route 34|US&nbsp;34]].

The Roosevelt Highway Association continued to push for an extension,<ref>{{cite news |work = McKean County Democrat |title =  Roosevelt Highway Association Renders Valuable Services |date = December 26, 1935 }}</ref> and, in December 1936, the [[American Association of State Highway Officials]] made US&nbsp;6 (and thus the Roosevelt Highway) a transcontinental route from Cape Cod, Massachusetts, to [[Long Beach, California]].<ref>{{cite news |work = [[Times Independent]] |url = http://udn.lib.utah.edu/u?/timesindep1,21182 |title = Roosevelt Highway at Last Gets Official Routing over No. 50 |date = December 31, 1936 |page = 5  |archive-url = https://web.archive.org/web/20120215075904/http://udn.lib.utah.edu/u?%2Ftimesindep1%2C21182 |archive-date=February 15, 2012 }}</ref><ref>{{cite news |work = [[Wellsboro Agitator]] |date = January 6, 1937 |quote = The action taken at the recent San Francisco meeting of the American Association of State Highway Officials now gives it a single federal highway number from the Atlantic to the Pacific. }}</ref> It took a new route from [[Wiggins, Colorado]], southwest to [[Denver]] (the old route to Greeley became an extended [[U.S. Route 34|US&nbsp;34]]{{Citation needed|date=July 2007}}) and west over the [[Rocky Mountains]] to [[Leadville, Colorado|Leadville]], overlapping [[U.S. Route 24|US&nbsp;24]] to [[Grand Junction, Colorado|Grand Junction]] and [[U.S. Route 50|US&nbsp;50]] to [[Spanish Fork, Utah]]. From Spanish Fork to [[Ely, Nevada]], it followed a roadway that had yet to be improved in areas; the rest of the route, from Ely to [[Southern California]], followed the old [[Midland Trail]], running almost north–south in California. The unimproved segment from Ely east to [[Delta, Utah]], about {{convert|160|mi|km}} long, was, according to ''[[BusinessWeek]]'', "nothing but a wagon trail-rutted, filled with dust [...] one of the worst chunks of federal road in the country". Paving was completed in September 1952, with a two-day celebration in Delta marking the occasion.<ref name="FHWA" />

Major [[William L. Anderson, Jr.]], of the [[U.S. Army]] recommended that US&nbsp;6 be designated the Grand Army of the Republic Highway, honoring the [[Union (American Civil War)|Union]] soldiers in the [[American Civil War|Civil War]]. The [[Sons of Union Veterans of the Civil War]] began pushing for the name in April 1934. Massachusetts, the first state to apply the name, passed a law to do so on February 2, 1937; it was not until at least 1948 that all states had agreed. The highway was formally dedicated at the [[Long Beach, California|Long Beach]] end on May 3, 1953,<ref name="FHWA" /> though the Roosevelt Highway Association continued to exist at least through the 1960s.<ref>{{cite news |work = McKean County Democrat |title = 4-Lane Rt. 6 plan to be Discussed in Smethport |date = February 17, 1966 }}</ref>

===Modern history===
As part of the [[1964 state highway renumbering (California)|1964 state highway renumbering]] in California, US&nbsp;6 was truncated to its intersection with [[U.S. Route 395|US&nbsp;395]] at [[Bishop, California|Bishop]]. The portions of the former route that did not overlap other routes, including US&nbsp;395 and [[Interstate 110 and State Route 110 (California)|I-110/SR&nbsp;110]], were redesignated as [[California State Route 14|SR&nbsp;14]].<ref name=FHWA/><ref>[[California Highway Department]], [http://www.cahighways.org/maps-sc-renumber.html 1963 State Highway Map and 1963 District VII State Highway Numbering Map]</ref>

Starting in early 1983, US&nbsp;6 was a discontinuous route for almost one year, due to a massive landslide that destroyed the town of [[Thistle, Utah]]. The highway was rebuilt by blasting a path higher up the canyon wall. The landslide remains the most costly in the history of the U.S.

Since the 1970s, portions of US&nbsp;6 in Iowa have been moved permanently onto I-80. The first section, between US&nbsp;71 and Adair, was rerouted in 1972.<ref name=DOT1973>{{Cite IowaDOT map|access-date=September 29, 2010|year=1973|link=no}}</ref> In 1980, three lengthy sections were moved onto the Interstate: {{convert|26|mi|km}} in western Iowa between Adair and Dexter,<ref name="Iowa 925">{{Google maps|title=Overview of Iowa 925|url=https://maps.google.com/maps?f=d&source=s_d&saddr=5th+St%2FCo+Rd+N54&daddr=US-6+E%2FEl+Paso+Ave&hl=en&geocode=FZ8jeQId3tpb-g%3BFdhzeQIdDq5i-g&gl=us&mra=ls&dirflg=h&sll=41.485434,-94.31488&sspn=0.263364,0.441513&ie=UTF8&z=10|access-date=September 29, 2010}}</ref> {{convert|25|mi|km}} in central Iowa between Altoona and Newton,<ref name="Iowa 926">{{Google maps|title=Overview of Iowa 926|url=https://maps.google.com/maps?f=d&source=s_d&saddr=NE+46th+Ave%2F8th+St+SW%2FNE+Broadway+Ave&daddr=1st+Ave+W&hl=en&geocode=FURwewId-gdt-g%3BFf5GfAIdCMZz-g&gl=us&mra=mift&mrsp=1&sz=16&dirflg=h&sll=41.698888,-93.074756&sspn=0.008203,0.013797&ie=UTF8&ll=41.702653,-93.326111&spn=0.524958,0.883026&z=10|access-date=September 29, 2010}}</ref> and {{convert|20|mi|km}} in eastern Iowa between Wilton and Davenport.<ref name="Iowa 927">{{Google maps|title=Overview of Iowa 927|url=https://maps.google.com/maps?f=d&source=s_d&saddr=IA-38+S%2FUS-6+W&daddr=W+Kimberly+Rd&hl=en&geocode=FQqeegIdzd2S-g%3BFeSjegIdqmOY-g&gl=us&mra=mift&mrsp=1&sz=16&dirflg=h&sll=41.592546,-90.676925&sspn=0.008217,0.013797&ie=UTF8&ll=41.574361,-90.854187&spn=0.526004,0.883026&z=10|access-date=September 29, 2010}}</ref> On July 1, 2003, {{convert|15|mi|km}} between Dexter and Adel were turned over to Dallas County.<ref name="Petroski">{{cite news|title=Road Transfer Draws Worry|last=Petroski|first=William|date=July 1, 2003|work=The Des Moines Register|page=B1}}</ref> US&nbsp;6, which had previously split away from I-80 at the Dexter exit, was continued along I-80 to the US&nbsp;169 interchange at De Soto, and then along US&nbsp;169 to Adel.<ref>{{Cite IowaDOT map|access-date=December 27, 2013|year=2003|link=no}}</ref><ref name=DOT2004>{{Cite IowaDOT map|access-date=September 29, 2010|year=2004|link=no}}</ref>

In 2015, the [[American Association of State Highway and Transportation Officials]] (AASHTO) approved a request from the [[Colorado Department of Transportation]] to eliminate US&nbsp;6 through the city of [[Rifle, Colorado|Rifle]], meaning that US&nbsp;6 is now discontinuous between Rifle and [[Grand Junction, Colorado|Grand Junction]], although current signage does not reflect this change.<ref>{{AASHTO minutes |year= 2015S |access-date= June 6, 2015}}</ref>
