'''Interstate&nbsp;91''' ('''I-91''') is an [[Interstate Highway System|Interstate Highway]] in the [[New England]] region of the United States. It is the primary north–south thoroughfare in the western part of the region. Its southern terminus is in [[New Haven, Connecticut]],<ref>{{google maps |url= https://maps.google.com/maps?q=New+Haven,+CT&ll=41.302765,-72.914028&spn=0.014517,0.022505&hl=en |title= New Haven, CT |access-date= June 8, 2009}}</ref> at [[Interstate 95|I-95]], while the northern terminus is in [[Derby Line, Vermont]], at the [[Canada–United States border]]. Past the [[Derby Line–Rock Island Border Crossing]], the road continues into Canada as [[Quebec Autoroute 55]]. I-91 is the longest of three Interstate highways whose entire route is located within the New England states (the other two highways being [[Interstate 89|I-89]] and [[Interstate 93|I-93]]) and is also the only primary (two-digit) Interstate Highway in New England to intersect all five of the other highways that run through the region. The largest cities along its route, from south to north, are [[New Haven, Connecticut]]; [[Hartford, Connecticut]]; [[Springfield, Massachusetts]]; [[Northampton, Massachusetts]]; [[Greenfield, Massachusetts]]; [[Brattleboro, Vermont]]; [[White River Junction, Vermont]]; [[St. Johnsbury, Vermont]]; and [[Newport (city), Vermont|Newport, Vermont]].

I-91 is {{convert|290|mi|km}} long and travels north and south: {{convert|58|mi|km}} in [[Connecticut]], {{convert|55|mi|km}} in [[Massachusetts]], and {{convert|177|mi|km}} in [[Vermont]]. I-91 parallels [[U.S. Route 5|US Route&nbsp;5]] (US&nbsp;5) for all of its length, and many of the exits along I-91 provide direct or indirect access to the older route. Much of the route of I-91 follows the [[Connecticut River]], traveling from [[Hartford, Connecticut]], northward to [[St. Johnsbury, Vermont]].<ref>{{cite web |url = http://www.town.berlin.ct.us/topic/subtopic.php?topicid=34&structureid=15 |title = Background Information on the Interstate |publisher = Town of Berlin, Connecticut |access-date = December 29, 2017 |archive-date = December 30, 2017 |archive-url = https://web.archive.org/web/20171230115108/http://www.town.berlin.ct.us/topic/subtopic.php?topicid=34&structureid=15 |url-status = live }}</ref><ref>{{cite book |last1 = Rogers |first1 = Barbara |title = Massachusetts Off the Beaten Path: A Guide to Unique Places |date = 2003 |publisher = Globe Pequot Press |isbn = 9780762726059 |url = https://books.google.com/books?id=tUy44WnW9h0C&q=I-91+parallel+route-5 |access-date = August 19, 2019 |via = [[Google Books]] |language = en |archive-date = January 14, 2023 |archive-url = https://web.archive.org/web/20230114200613/https://books.google.com/books?id=tUy44WnW9h0C&q=I-91+parallel+route-5 |url-status = live }}</ref><ref>{{cite book |first = Vernon |last = Nahrgang |title = Fodor's91 New England |date = 2003 |page = 359 |publisher = Fodor's Travel Publications |isbn = 9780679019367 |url = https://books.google.com/books?id=5X-SJb3FUf8C&q=I-91+parallel+route-5 |access-date = August 19, 2019 |via = [[Google Books]] |language = en |archive-date = January 14, 2023 |archive-url = https://web.archive.org/web/20230114200613/https://books.google.com/books?id=5X-SJb3FUf8C&q=I-91+parallel+route-5 |url-status = live }}</ref>

I-91 is the major north–south transportation corridor for the center of the state. It is the main route between the larger cities of New Haven, Hartford, and [[Springfield, Massachusetts]]. As such, it is almost always heavily trafficked (especially during rush hour) and maintains at least three lanes in each direction through Connecticut except for a short portion in Hartford at the interchange with [[Interstate 84 (Pennsylvania–Massachusetts)|I-84]], and another in [[Meriden, Connecticut|Meriden]] at the interchange with [[Connecticut Route 15|Route&nbsp;15]]. The three cities also serve as Connecticut's control points along its length of the Interstate.<ref>{{cite book |last1 = Boyle |first1 = Doe |title = Fun with the Family Connecticut: Hundreds of Ideas for Day Trips with the Kids |date = 2011 |publisher = Rowman & Littlefield |isbn = 978-0-7627-6879-0 |url = https://books.google.com/books?id=xic1huFa1ZEC&pg=PA144 |access-date = August 10, 2018 |via = [[Google Books]] |language = en |archive-date = January 14, 2023 |archive-url = https://web.archive.org/web/20230114200616/https://books.google.com/books?id=xic1huFa1ZEC&pg=PA144 |url-status = live }}</ref><ref name="impact">{{cite book |author = Bureau of Planning and Research |title = I-91 Reconstruction from Hartford to Enfield; I-291 Construction from Windsor to Manchester: Environmental Impact Statement |date = August 1984 |url = https://books.google.com/books?id=Lbs1AQAAMAAJ&pg=PA49 |access-date = August 10, 2018 |via = Google Books |language = en |page = 49 |location = [Wethersfield, CT] |publisher = [Connecticut Department of Transportation] |oclc = 53099516 |archive-date = January 14, 2023 |archive-url = https://web.archive.org/web/20230114200613/https://books.google.com/books?id=Lbs1AQAAMAAJ&pg=PA49 |url-status = live }}</ref>

=== Vermont ===
I-91 traverses the entire length of [[Vermont]] and serves as a major transportation corridor for eastern Vermont and western [[New Hampshire]]. Due to its routing along the Connecticut River separating the two states, many exits along Vermont's length of I-91 feature New Hampshire towns on the guide signs (for example, exit&nbsp;3, which lists [[Brattleboro, Vermont|Brattleboro]] and [[Keene, New Hampshire]], as the points of access). The length of I-91 within Vermont is {{convert|177|mi|km}} and has two lanes in each direction the entire way from the Massachusetts state line to the Canada–United States border (nearly two-thirds of I-91's length) with 29 Vermont interchanges. The highway's rural character and long distances between exits in Vermont are in stark contrast to its south, where exits are more frequent and the road carries four lanes of traffic in each direction at some points. The major control cities in Vermont are Brattleboro, [[White River Junction, Vermont|White River Junction]], [[St. Johnsbury, Vermont|St. Johnsbury]], and [[Newport (city), Vermont|Newport]]. When entering northbound I-91 at exit&nbsp;28 in [[Derby, Vermont|Derby]], the control city sign is for Canada. Of these destinations, only Newport is a city, although the other towns are sizable. In general, the road parallels its predecessor, US&nbsp;5.<ref>{{google maps |link = no |url=https://www.google.com/maps/dir/42.730126,-72.5698703/45.0058814,-72.0876317/@45.0062274,-72.0894927,17.96z|title=Interstate 91 in Vermont|access-date=August 13, 2019}}</ref><ref>{{cite book |last1 = Tree |first1 = Christina |last2 = Foulds |first2 = Diane E. |title = Explorer's Guide Vermont |date = 2009 |publisher = The Countryman Press |isbn = 9780881508482 |url = https://books.google.com/books?id=MvkoQmVCQlMC&pg=PA238 |access-date = 17 August 2019 |language = en |archive-date = January 14, 2023 |archive-url = https://web.archive.org/web/20230114200615/https://books.google.com/books?id=MvkoQmVCQlMC&pg=PA238 |url-status = live }}</ref><ref>{{cite book |last1 = Tree |first1 = Christina |last2 = Hamm |first2 = Christine |last3 = Imbrie |first3 = Katherine |title = Explorer's Guide New Hampshire |date = 2010 |publisher = The Countryman Press |isbn = 9780881508413 |url = https://books.google.com/books?id=QpvEeOtVBXsC&pg=PA194 |access-date = 17 August 2019 |language = en |archive-date = January 14, 2023 |archive-url = https://web.archive.org/web/20230114200615/https://books.google.com/books?id=QpvEeOtVBXsC&pg=PA194 |url-status = live }}</ref>

I-91 enters Vermont in the town of Guilford. Just before exit&nbsp;1 in Brattleboro is the Vermont Welcome Center in Guilford. The first three Vermont exits (northbound) serve the town of Brattleboro. At exit&nbsp;1, northbound US&nbsp;5 provides access to stores and a small industrial area before reaching the south end of the town's center, where a bridge crosses the Connecticut River into [[Hinsdale, New Hampshire]], via [[New Hampshire Route 119|New Hampshire Route&nbsp;119]] (NH&nbsp;119). Exit&nbsp;2 ([[Vermont Route 9|Vermont Route&nbsp;9]] [VT&nbsp;9]) provides access to the western village of the town ([[West Brattleboro, Vermont|West Brattleboro]]), then continues west to [[Marlboro, Vermont|Marlboro]], [[Wilmington, Vermont|Wilmington]], and [[Bennington, Vermont|Bennington]].

A limited-access highway replacement for [[U.S. Route 5|US&nbsp;5]] was planned at the federal level starting in 1944. A 1953 Massachusetts plan was funded by the [[Federal-Aid Highway Act of 1956]], along with spur [[Interstate 291 (Massachusetts)|I-291]] (but not [[Interstate 391|I-391]]). The Vermont section of I-91 was built in stages from 1958 to 1965.<ref>{{cite web |url = http://digital.vpr.net/post/four-decades-36000-photographs-construction-i-89-and-i-91#stream/0 |title = Building of Vermont section |date = November 21, 2013 |publisher = digital.vpr.net |access-date = January 5, 2018 |archive-date = January 6, 2018 |archive-url = https://web.archive.org/web/20180106065029/http://digital.vpr.net/post/four-decades-36000-photographs-construction-i-89-and-i-91#stream/0 |url-status = live }}</ref> In Massachusetts from [[Bernardston, Massachusetts|Bernardston]] to [[Northampton, Massachusetts|Northampton]], I-91 follows an abandoned [[Right-of-way (transportation)|right-of-way]] of the [[New York, New Haven and Hartford Railroad]].

Later, this path was perceived as cutting off the city from the river, restricting further commercial development. By 1960, a few miles in Massachusetts were completed, starting from the Connecticut and Vermont state lines.

In the 1950s–1970s, there were [[Long Island Sound link|plans]] to extend I-91 to [[Wading River, New York]], from its existing terminus in [[New Haven, Connecticut]], via a crossing of the [[Long Island Sound]] (see "Unbuilt Long Island extension" below).<ref name=":0">{{cite news |url = http://future.newsday.com/10/fgsound.htm |archive-url = https://web.archive.org/web/20040710174432/http://future.newsday.com/10/fgsound.htm |archive-date = July 10, 2004 |work = Newsday |last = Madden |first = Steve |title = Spanning the Sound |access-date = September 18, 2015 |url-status = unfit }}</ref> Vermont completed its last sections of I-91 in 1978.<ref>{{cite web |url = http://www.historicvermont.org/sites/html/history.html |title = Vermont History Timeline |work = HistoricVermont.org |author = Division for Historic Preservation |publisher = [[Vermont Agency of Commerce and Community Development]] |date = n.d. |access-date = December 17, 2011 |archive-url = https://web.archive.org/web/20110927035345/http://www.historicvermont.org/sites/html/history.html |archive-date = September 27, 2011 }}</ref>

Starting in the 1990s, several rest areas were downgraded in Vermont, increasing distances between facilities. In 2008, Vermont closed the Springfield–Rockingham rest areas because of suspected use by drug abusers. In 2009, the northbound rest area in Hartford was closed, creating a {{convert|90|mi|km|adj=on}} gap in on-highway facilities. At the present time, there exist two intermediate rest areas with facilities in each direction, in addition to a welcome center at each end of the state.

In the early 1990s after the [[Interstate 284|I-284]] project was canceled, the exit&nbsp;44 interchange in [[East Windsor, Connecticut]], was altered as it was designed to be part of the freeway. After alterations, exit&nbsp;44 connected to US&nbsp;5 for all traffic to get on and off. As a result, exit&nbsp;43 was shut down and closed in that same time frame. Exit&nbsp;43 was a northbound exit/southbound entrance on [[Connecticut Route 510|Route&nbsp;510]]/Main Street in East Windsor, which was about {{convert|320|m|ft|order=flip}} away from exit&nbsp;44.

=== Impact in Springfield, MA ===
[[File:I-91 Springfield viaduct meets completion, Massachusetts Dept of Public Works.jpg|thumb|right|I-91 in 1969, just after completion of the viaduct which would separate Springfield from the Connecticut River.

During its construction in the 1960s, I-91 sliced through three Springfield neighborhoods: the [[North End, Springfield, Massachusetts|North End]], [[Metro Center, Springfield, Massachusetts|Metro Center]], and [[South End, Springfield, Massachusetts|South End]], which led to [[urban decay]] in the highway's vicinity. Springfield's portion of the Interstate was widely regarded as positive progress when it was built. However, by the 2010s, it would come to be perceived as disrupting the urban fabric of riverfront neighborhoods while effectively disconnecting the [[Connecticut River]], the [[Connecticut River Walk Park]] and the [[Naismith Memorial Basketball Hall of Fame]] from everything east of the highway—the majority of the city. I-91 was erected without tunnels, footbridges or other paths, a design choice which poses logistical problems for travel between the riverfront and the remainder of the city. This, in turn, poses problems for businesses that would like to set up along the riverfront. The placement of I-91 has left Springfield's riverfront virtually undeveloped, aside from the sliver of land surrounding the Basketball Hall of Fame.<ref>{{cite news |author = The Republican Editorials |date = February 26, 2010 |title = Editorial: Tapping Potential of Springfield's Riverfront |work = MassLive |url = http://www.masslive.com/opinion/index.ssf/2010/02/editorial_tapping_potential_of.html |access-date = December 17, 2011 |archive-date = September 25, 2012 |archive-url = https://web.archive.org/web/20120925032705/http://www.masslive.com/opinion/index.ssf/2010/02/editorial_tapping_potential_of.html |url-status = live }}</ref>

In 2010, the [[Urban Land Institute]] made recommendations for how Springfield might reconnect with its riverfront, in order to revitalize the area through [[urban renewal]], suggesting the most cost-effective but also the most development-limiting strategy (constructing pathways beneath I-91). No decision has been reached regarding those recommendations.<ref>{{cite web |author = Office of Planning and Economic Development |date = 2008 |title = River's Landing Project |url = http://www.springfieldcityhall.com/planning/riverfront-proj.0.html |archive-url = https://web.archive.org/web/20080703195451/http://www.springfieldcityhall.com/planning/riverfront-proj.0.html |archive-date = July 3, 2008 |access-date = December 17, 2011 |publisher = City of Springfield, MA }}</ref> {{As of|2011}}, academic and civic studies are still underway. Preliminary findings indicate that I-91's placement negatively impacts tourism in Springfield's Metro Center—the site of many of Springfield's historic, cultural, and entertainment venues. Springfield's most popular tourist attraction, the riverfront Basketball Hall of Fame, is separated from Metro Center by a {{convert|20|ft|m|adj=on}} stone wall, buttressing an elevated portion of the six-lane I-91 and greatly discouraging travel between the two areas. Academic suggestions that involve the demolition of the current highway and moving it to a less obtrusive site in the city have been proposed, including the demolition of the highway and following the original path suggested, Riverdale Road, and, least obtrusive but still requiring a great deal of work, a plan to construct numerous walkways beneath the elevated highway to better integrate the neighborhoods with the waterfront despite the highway's presence.<ref>{{cite web |last1 = Fay |first1 = Tony |date = January 29, 2016 |title = Long term solutions: What could become of I-91 in Springfield? |url = https://www.wwlp.com/news/local-news/hampden-county/long-term-solutions-what-could-become-of-i-91-in-springfield/1043655415 |access-date = August 15, 2018 |location = Springfield, Massachusetts |publisher = WWLP-TV |archive-date = October 1, 2020 |archive-url = https://web.archive.org/web/20201001060252/https://www.wwlp.com/news/local-news/hampden-county/long-term-solutions-what-could-become-of-i-91-in-springfield/1043655415/ |url-status = live }}</ref>

=== Unbuilt Long Island extension ===
{{Interstate 91 Extension}}
Between the 1950s and 1970s, officials proposed extending I-91 across the [[Long Island Sound]] from its current terminus at the I-91/[[Interstate 95|I-95]] interchange in [[New Haven, Connecticut]], to [[Wading River, New York]], by means of a bridge over the Long Island Sound, as one of the many [[Long Island Sound link|Long Island Sound Link]] proposals.<ref name=":0" /> The extension would have continued southward from Wading River to the southern shore of [[Long Island]] by the existing [[County Route 46 (Suffolk County, New York)|County Route&nbsp;46]] (William Floyd Parkway) in central [[Suffolk County, New York|Suffolk County]]—which would have been updated to [[Interstate Highway standards]]. It would also provide easier access to New York City via the [[Interstate 495 (New York)|Long Island Expressway]] (I-495), as well as to [[the Hamptons]] via [[New York State Route 27]] (Sunrise Highway). The various proposals for this never-built extension were ultimately dropped after a 1979 study of the concept.<ref>{{cite news |last = Stannard |first = Charles |date = May 14, 2002 |title = The Bridge That Never Was: Cable Flap Brings To Mind Sound-Crossing Controversy |work = [[Hartford Courant]] |url = https://www.courant.com/2002/05/14/the-bridge-that-never-was/ |access-date = September 18, 2015 |archive-date = September 23, 2015 |archive-url = https://web.archive.org/web/20150923060937/http://articles.courant.com/2002-05-14/news/0205141460_1_long-island-sound-bridge-project-chesapeake-bay-bridge-tunnel |url-status = live }}</ref> Following this, officials proposed to connect the New Haven and [[Shoreham, New York|Shoreham]]–Wading River areas by means of ferry service across the Long Island Sound—however, the plans to implement these cross-sound ferry services were ultimately mothballed, as well.<ref>{{cite web |last = Anderson |first = Steve |title = William Floyd Parkway |url = http://www.nycroads.com/roads/CR-46/ |access-date = March 18, 2010 |work = NYCRoads |archive-date = June 6, 2010 |archive-url = https://web.archive.org/web/20100606072306/http://www.nycroads.com/roads/CR-46/ |url-status = live }}{{sps|certain=yes|date=July 2020}}</ref>
