The '''Baltimore–Washington Parkway''' (also referred to as the '''B–W Parkway''') is a [[controlled-access highway|controlled-access]] [[parkway]] in the [[U.S. state]] of [[Maryland]], running southwest from [[Baltimore]] to [[Washington, D.C.]] The road begins at an interchange with [[U.S. Route 50 in Maryland#Prince George's County|U.S. Route&nbsp;50]] (US&nbsp;50) near [[Cheverly, Maryland|Cheverly]] in [[Prince George's County, Maryland|Prince George's County]] at the Washington, D.C., border, and continues northeast as a [[parkway]] maintained by the [[National Park Service]] (NPS) to [[Maryland Route 175|MD&nbsp;175]] near [[Fort Meade]], serving many federal institutions.  This portion of the parkway is dedicated to [[Gladys Spellman|Gladys Noon Spellman]], a representative of [[Maryland's 5th congressional district]], and has the [[unsigned highway|unsigned]] '''Maryland Route&nbsp;295''' ('''MD&nbsp;295''') designation. [[Commercial vehicles]], including trucks, are prohibited within this stretch. This section is administered by the NPS's [[Greenbelt Park]] unit.<ref name="NPSgreenbelt">{{cite web |url = https://home.nps.gov/bawa/learn/management/index.htm |title = Baltimore–Washington Parkway Management |publisher = [[National Park Service]] }}</ref> After leaving park service boundaries the highway is maintained by the state and signed with the MD&nbsp;295 designation. This section of the parkway passes near [[Baltimore–Washington International Thurgood Marshall Airport]].

Upon entering Baltimore, the [[Baltimore Department of Transportation]] takes over maintenance of the road and it continues north to an interchange with [[Interstate 95 in Maryland|Interstate&nbsp;95]] (I-95). Here, the Baltimore–Washington Parkway ends and MD&nbsp;295 continues north unsigned on '''Russell Street''', which carries the route north into [[downtown Baltimore]]. In downtown Baltimore, MD&nbsp;295 follows [[Paca Street]] northbound and [[Greene Street]] southbound before ending at [[U.S. Route 40 in Maryland|US&nbsp;40]].

Plans for a parkway linking Baltimore and Washington date back to [[Pierre Charles L'Enfant]]'s original layout for Washington, D.C. in the 18th century but did not fully develop until the 1920s. Major reasons surrounding the need for a parkway included high accident rates on adjacent [[U.S. Route 1 in Maryland|US&nbsp;1]] and defense purposes before [[World War II]]. In the mid-1940s, plans for the design of the parkway were finalized and construction began in 1947 for the state-maintained portion and in 1950 for the NPS-maintained segment. The entire parkway opened to traffic in stages between 1950 and 1954.

Following completion of the B–W Parkway, suburban growth took place in both Washington, D.C. and Baltimore. In the 1960s and the 1970s, there were plans to give the segment of the parkway owned by the NPS to the state and make it a part of [[Interstate 295 (Maryland)|I-295]] and possibly I-95; however, they never came through and the entire road is today designated as MD&nbsp;295, despite only being signed on the state-maintained portion. Between the 1980s and the 2000s, the NPS portion of the road was modernized. MD&nbsp;295 is in the process of being widened from four to six lanes, with more widening and a new interchange along this segment planned for the future.

The parkway begins at a large hybrid [[cloverleaf interchange|cloverleaf]] just outside the [[Washington, D.C.]], boundary at [[Tuxedo, Maryland]], that is maintained by the [[Maryland State Highway Administration]].<ref name=MarylandHLR/> Two other routes cross through the interchange. [[U.S. Route 50 in Maryland|US&nbsp;50]] west of the interchange heads into Washington, D.C., to become [[New York Avenue (Washington, D.C.)|New York Avenue]], and to its east becomes the [[U.S. Route 50 in Maryland#Prince George's County|John Hanson Highway]], a [[controlled-access highway|freeway]].  [[Maryland Route 201|MD&nbsp;201]], which begins just south of the interchange at the D.C. line as a continuation of [[D.C. Route 295|D.C.

=== Planning ===
Plans for a parkway connecting Baltimore and Washington date back to the 1920s as a part of a system that was initially included in [[Pierre Charles L'Enfant]]'s layout of Washington, D.C., from the 18th century.<ref name="dhr"/> In 1924, [[Harry W. Nice]], who would later become [[governor of Maryland]], called for the parkway to be constructed.<ref name="bmetro">{{cite web |url = http://www.baltometro.org/reports/MajorTransMilestones.pdf |title = Major transportation milestones in the Baltimore region since 1940 |publisher = Baltimore Metropolitan Council |access-date = April 21, 2009 |url-status = dead |archive-url = https://web.archive.org/web/20101227234104/http://www.baltometro.org/reports/MajorTransMilestones.pdf |archive-date = December 27, 2010 }}</ref>

Early proposals made by the [[National Capital Planning Commission|National Capital Park and Planning Commission]] involved a route that followed [[U.S. Route 1 in Maryland|US&nbsp;1]] north to MD&nbsp;198, then east to Fort Meade, but lack of funding led to simpler plans to widen US 1 instead. During the 1930s, the [[New Deal]] programs promulgated by President [[Franklin Roosevelt]] led to a heightened awareness of the parkway proposals; a 1937 report by the Maryland State Planning Commission increased awareness further.<ref name="sun">{{cite news |first = Avery |last = McBee |title = Baltimore–Washington Parkway: A New Link Is Projected with the Nation's Capital |work = [[The Baltimore Sun]] (Sunday Sun Magazine) |date = October 11, 1936 |page = 3 }}</ref> Increasing accident levels on US 1 (which was called one of the deadliest roads in the world at the time) along with awareness of the need to mobilize national defense before [[World War II]] provided additional motivation for construction of the parkway.<ref name="dhr">{{cite web |url = http://www.dhr.virginia.gov/registers/Counties/MultipleCounty/029-5524_ParkwaysCapitalRegionMPD_1990_finalnomination.pdf |title = Parkways of the National Capital Region, 1913 - 1965 |publisher = National Park Service |access-date = April 22, 2009 |archive-url = https://web.archive.org/web/20090502190011/http://www.dhr.virginia.gov/registers/Counties/MultipleCounty/029-5524_ParkwaysCapitalRegionMPD_1990_finalnomination.pdf |archive-date = May 2, 2009 |url-status = live }}</ref><ref>{{cite web |url = http://lcweb2.loc.gov/pnp/habshaer/md/md1400/md1496/data/md1496data.pdf |title = Baltimore–Washington Parkway |last = Duensing |first = Dawn |date = 2000 |website = Historic American Engineering Record |publisher = Library of Congress |location = Washington, D.C. |page = 1 |access-date = March 2, 2014 }}</ref>

In 1963, the State Roads Commission, the National Park Service, and the Bureau of Public Roads (the predecessor of the [[Federal Highway Administration]]) (FHWA) created tentative plans to transfer the NPS segment of the parkway to the state of Maryland, who would then rebuild it to modern freeway standards, with trucks and buses permitted throughout.<ref name="bnp">{{cite news |title = State to Get DC Parkway |work = [[Baltimore News-Post]] |date = August 16, 1963 }}{{page needed|date=November 2017}}</ref> The plan collapsed due to the state's reluctance to spend the money necessary to reconstruct the parkway, which was one of the most dangerous roads in the NPS road system.<ref name="sun2">{{cite news |title = State Is Found Unwilling to Take Over the Parkway |work = The Baltimore Sun |date = April 20, 1969 |page = 20 }}</ref>

In 1968, the State Roads Commission proposed to the FHWA that the parkway be included in the [[Interstate Highway System]] and designated Interstate&nbsp;295 (in anticipation of the completion of the parallel-running I-95 that occurred in 1971). The designation was granted in 1969, but later withdrawn from all except the current portion signed as I-295 due to lack of funds available to modernize the route.<ref name="sun3">{{cite news |first = Horace |last = Ayres |title = Parkway Won't Become Part of Interstate |work = The Evening Sun |location=Baltimore, Maryland |date = August 22, 1969 |page = C4}}</ref> As a result of the withdrawal of the Interstate designation, the parkway remained an unnumbered road south of I-695 while the portion north of there became a part of [[Maryland Route 3|MD&nbsp;3]] by 1975.<ref name="exxon1975"/> Despite this setback, however, plans still existed to widen the parkway to six or even eight lanes.

The cancellation of the [[North Central Freeway (DC)|North Central Freeway]] and the [[Northeast Freeway (Washington, D.C.)|Northeast Freeway]] (I-95's routing between New York Avenue and the [[College Park Interchange]]) offered a chance for modernization, as plans existed to route I-95 via the B–W Parkway; however, this did not happen and trucks were banned from the parkway again.<ref name="sun4">{{cite news |first = James D. |last = Dilts |title = Battle Brews on Widening of Baltimore-DC Road |work = The Baltimore Sun |date = December 9, 1974 |page = C1 }}</ref><ref name="sun5">{{cite news |first = Barry C. |last = Rascovar |title = Parkway Plans Narrowed |work = The Baltimore Sun |date = July 5, 1976 |page = C1 }}</ref>

The [[Maryland State Highway Administration]] closed the southbound ramps of the interchange between the Baltimore–Washington Parkway and Arundel Mills Boulevard starting Monday, May 7, 2012.

=== Dedications ===
In 1983, the NPS-maintained section of the Baltimore–Washington Parkway was named in honor of [[Gladys Noon Spellman]], a [[United States Congress|congresswoman]] who represented [[Maryland's 5th congressional district]] from January 3, 1975, to January 3, 1981, after a bill introduced into the [[United States Senate]] by Senator [[Paul Sarbanes]] was signed into law.<ref name=govtrack>{{cite web |url = https://www.govtrack.us/congress/bills/98/s680 |title = S.680 A bill entitled the "Gladys Noon Spellman Parkway." |publisher = GovTrack |access-date = August 14, 2021 }}</ref> Gladys Noon Spellman was an educator in [[Prince George's County, Maryland|Prince George's County]] and chairperson of the National Mental Health Study Center before becoming the first woman to serve on the county's Board of Commissioners.

=== Incidents ===
In 1989, an [[overpass]] being built at MD&nbsp;198 over the B–W Parkway just east of Laurel collapsed during rush hour, injuring fourteen motorists and construction workers. The incident was blamed on faulty scaffolding used to support the uncompleted span.<ref name="wpcollapse">{{cite news |last = Duggan |first = Paul and Veronica T.

MD&nbsp;295 is planned to be widened to six lanes between MD&nbsp;100 and I-195, and a new interchange is planned to be constructed at Hanover Road. The type of interchange has not yet been decided upon with choices including a [[diamond interchange]], a [[single-point urban interchange]], and a modified cloverleaf interchange.

In September 2017, Governor [[Larry Hogan]] announced a plan to widen the Baltimore–Washington Parkway by four lanes, adding [[express toll lane]]s to the median, as part of a $9 billion proposal to widen roads in Maryland. The project would be a public-private partnership with private companies responsible for constructing, operating, and maintaining the lanes. As part of the proposal, the portion of the parkway owned by the National Park Service would be transferred to the [[Maryland Transportation Authority]].<ref name=wtop>{{cite web |url = http://wtop.com/maryland/2017/09/hogan-proposes-9b-plan-add-new-lanes-beltway-270-bw-parkway/ |title = Hogan proposes $9B plan to add new lanes to Beltway, 270 and BW Parkway |date = September 21, 2017 |publisher = WTOP-FM |location = Washington, DC |access-date = September 21, 2017 }}</ref>

In 2019, portions of the National Park Service segment of the Baltimore–Washington Parkway experienced significant pavement deterioration, including several potholes. In March 2019, the speed limit was reduced on the section of the parkway between MD&nbsp;197 and MD&nbsp;32 due to poor road conditions.<ref>{{cite news|last=Campbell|first=Colin|title=The potholes are so bad on a stretch of the Baltimore-Washington Parkway that the speed limit was lowered|work=The Baltimore Sun|date=March 5, 2019|url=https://www.baltimoresun.com/news/maryland/bs-md-baltimore-washington-parkway-speed-limit-20190305-story.html|access-date=March 28, 2019|archive-date=March 31, 2019|archive-url=https://web.archive.org/web/20190331230551/https://www.baltimoresun.com/news/maryland/bs-md-baltimore-washington-parkway-speed-limit-20190305-story.html|url-status=dead}}</ref> After pressure from Governor Hogan and the state's congressional delegation, the National Park Service announced that emergency pothole repairs would take place from MD&nbsp;197 to MD&nbsp;198 on the weekend of March 30–31, 2019, with a complete repave to begin in April 2019, several months ahead of schedule.
