MD 210

MD 210 is a state highway in Maryland serving as a major commuter and connector route between Washington, D.C. and southern suburban nodes in Prince George's County. The route links arterial streets such as Pennsylvania Avenue and DC 295 with the Capital Beltway and provides access to facilities including Joint Base Andrews, National Harbor, and industrial corridors near Oxon Hill. The corridor has repeatedly appeared in planning discussions involving Maryland State Highway Administration, National Capital Planning Commission, and regional transit studies by the Metropolitan Washington Council of Governments.

Route description

MD 210 begins at the District of Columbia–Maryland border where Pennsylvania Avenue transitions near the Capitol Hill and Navy Yard approaches, proceeding northeast through suburban neighborhoods toward Joint Base Andrews. The highway passes adjacent to installations and institutions including Potomac River Regional Park, Oxon Hill Farm, and commercial nodes near Temple Hills. MD 210 intersects major corridors and interchanges with I‑295, Maryland Route 5, and the Capital Beltway, providing connections to BWI Airport via Maryland Route 404 linkages and to National Harbor using nearby access roads. Along its alignment the route crosses or parallels watercourses such as Oxon Run and provides access to transit nodes serviced by Washington Metropolitan Area Transit Authority stations and commuter bus services operating from hubs like Southern Avenue station and park-and-ride lots near Capitol Heights station.

History

The corridor dates to early 20th-century improvements linked to George Washington Memorial Parkway planning and to wartime expansions associated with Langley Air Force Base supply routes. Federal and state cooperation accelerated upgrades during the World War II era to serve Andrews Air Force Base logistics, and subsequent postwar suburbanization tied the road to growth patterns documented by 1950s suburban development studies. Major improvement projects in the 1960s and 1970s added interchanges with Capital Beltway segments and realignment efforts coordinated with agencies such as the Federal Highway Administration, the Maryland-National Capital Park and Planning Commission, and municipal planners from Prince George's County. Later modernization phases incorporated safety upgrades influenced by standards promulgated by the American Association of State Highway and Transportation Officials and environmental reviews prompted by National Environmental Policy Act compliance. Recent decades have seen resurfacing, interchange reconstruction, and multimodal planning informed by regional initiatives from the National Capital Region Transportation Planning Board.

Major intersections

The highway's principal crossings and interchanges reflect connections to regional routes and federal roadways. Key junctions include the transition at Pennsylvania Avenue near the District of Columbia boundary, an interchange with I‑295 providing access to Anacostia, a junction with Maryland Route 5 near suburban commercial centers, and interchange ramps linking to the Capital Beltway (I‑95/I‑495) facilitating movements toward Baltimore and Silver Spring. Other notable intersections afford access to Joint Base Andrews, connections toward National Harbor, and local arterials serving communities such as Temple Hills, Suitland, and Forestville.

Related routes

Related corridors and numbered routes interoperate with MD 210, including Maryland Route 5 which continues southeast through Southern Maryland, Maryland Route 4 linking to Calvert County, and I‑295/I‑95 for long-distance travel. Proximate state highways such as Maryland Route 414, Maryland Route 458, and Maryland Route 337 provide local circulation and feeder access. Regional transit routes by the Washington Metropolitan Area Transit Authority, commuter bus operators like Washington Metrobus, and interjurisdictional planning by the Metropolitan Washington Council of Governments are functionally tied to the corridor. Federal roadway programs from the Federal Highway Administration and environmental oversight by the Environmental Protection Agency have influenced related projects.

Future developments

Planned and proposed projects affecting the corridor appear in county and metropolitan transportation plans maintained by the Maryland State Highway Administration and the National Capital Region Transportation Planning Board. Proposals include interchange reconfigurations to improve traffic flow near Joint Base Andrews, multimodal enhancements coordinating with Washington Metropolitan Area Transit Authority expansions, and safety improvements inspired by Vision Zero-style initiatives adopted in adjacent jurisdictions such as Arlington County and Alexandria, Virginia. Environmental permitting and funding discussions have engaged federal partners including the Federal Transit Administration and community stakeholders represented by Prince George's County Council and neighborhood associations from Capitol Heights and Suitland.
