Maryland Route 210

Maryland Route 210 is a state highway in Prince George's County, Maryland connecting Fort Washington with the District of Columbia boundary near Washington. The road links coastal sites such as Fort Washington National Park and suburban corridors including Oxon Hill, Bowie-area arterials, and commuter routes feeding into I-95 and I-495. The corridor serves residents accessing Joint Base Andrews, National Harbor, and institutions like University of Maryland facilities via regional connections.

Route description

Maryland Route 210 begins near Fort Washington National Park and traverses north through Fort Washington and Dunkirk-adjacent neighborhoods, intersecting local streets that provide access to Indian Head ferry connections and Piscataway Park. The highway becomes a divided arterial approaching Oxon Hill, where it meets ramp systems linked to Indian Head Highway and spurs toward National Harbor, MGM National Harbor, Gaylord National Resort, and transit nodes serving Alexandria and Annapolis. Continuing north, the route crosses Oxon Run and parallels rail rights-of-way near Suitland and Forestville before intersecting Pennsylvania Avenue (Baltimore–Washington) and urban connectors toward Metro stations that link with WMATA. Approaching the District of Columbia, the highway interfaces with ramps to Interstate 295 (District of Columbia) and commuter roads feeding into downtown Washington, Capitol Hill, and federal complexes like the Department of Defense headquarters area near Arlington.

History

The corridor which became the highway originated as early 20th-century roads serving plantation sites and coastal fortifications including Fort Washington National Park and related War of 1812 landmarks. Mid-century strategic growth linked the route to military installations such as Joint Base Andrews, prompting state upgrades after World War II. The road received its numeric designation in 1949 during a wave of Maryland highway renumbering that paralleled expansion of the Interstate Highway System and suburbanization driven by postwar programs like the G.I. Bill and federal agencies relocating to Washington. Through the 1950s and 1960s the route was widened to a divided highway in segments to serve commuting patterns influenced by developments such as District of Columbia suburbanization and projects tied to Anacostia River basin improvements. Later decades saw interchange construction connecting the route with I-95/I-495 capital beltway projects, transit-oriented planning involving WMATA expansions, and multimodal proposals related to Prince George's County growth, regional transit, and environmental mitigation for Piscataway Creek and Oxon Run restoration initiatives.

Major intersections

The highway provides major junctions with arterial and limited-access highways. Notable intersections include connections to Fort Washington Road near Fort Washington National Park, junctions with Branch Avenue-linked routes, a key interchange with Pennsylvania Avenue, and ramps joining the Capital Beltway (I-495) and I-95 corridors that facilitate access to Baltimore and Alexandria. The route also interfaces with collector roads serving Suitland Federal Center, National Harbor access roads serving hospitality projects like MGM National Harbor, and approaches to the District of Columbia boundary where traffic disperses toward I-295 and local arteries leading to federal districts including the National Mall and Pennsylvania Avenue NW.

Auxiliary routes

Several short spur and connector segments branch from the corridor to provide local access and ramp movements. These spurs link to park access points for Fort Washington National Park, service roads for Joint Base Andrews, and feeder streets serving Oxon Hill commercial districts and transit facilities near Suitland Metro Station. Auxiliary alignments include ramp stubs adjoining the Capital Beltway and frontage roads paralleling Branch Avenue and local rail crossings used historically by freight operators such as CSX Transportation and commuter lines associated with Amtrak corridors.

Future developments

Planned improvements emphasize multimodal capacity, safety enhancements, and environmental stewardship tied to regional plans coordinated by entities such as Maryland Department of Transportation, Prince George's County Department of Public Works and Transportation, and metropolitan planning organizations including the Metropolitan Washington Council of Governments. Projects under study include interchange modernization near the Capital Beltway, bus rapid transit or enhanced bus lanes connecting National Harbor with Washington Metro corridors, pedestrian and bicycle facility expansions to link parks like Piscataway Park with urban trails, and stormwater management upgrades to protect waterways including Oxon Run and the Potomac River. These efforts intersect with federal grant programs administered by agencies such as the Federal Highway Administration and environmental review processes involving the National Park Service for sites proximate to Fort Washington National Park.
