Maryland Route 210 (Indian Head Highway)

Maryland Route 210 (Indian Head Highway) is a state highway in the U.S. state of Maryland. The route connects Indian Head on the Potomac River with the Anacostia River and District of Columbia approaches via a controlled-access and arterial corridor serving Fort Washington, Joint Base Andrews, and suburban communities of Waldorf and Suitland. The highway functions as a regional connector between I-495/I-95 beltway facilities, MD 5, and US 301, carrying commuter, freight, and military-related traffic across Charles County and Prince George's County.

Route description

MD 210 begins near Indian Head and proceeds northeast as a four- to six-lane divided highway passing near Naval Support Activity Indian Head, Potomac River Naval Command facilities, and the Chesapeake Bay watershed. The corridor intersects MD 225 and continues past suburban nodes including Waldorf, providing access to MD 228 and US 301 before entering Prince George's County. Approaching Joint Base Andrews, the route meets MD 5 and transitions to a limited-access highway with interchanges for Marlboro Pike and Suitland Parkway-connected arterials serving Fort Washington and the Anacostia River crossings toward Washington. The highway terminates at the D.C. Route 295 boundary, linking into corridors used by traffic to US 1, I-395, and the Baltimore–Washington Parkway.

History

The route number dates to the 1927 era, while the present alignment was constructed and upgraded during the World War II and postwar expansion to serve naval facilities and growing Prince George's County suburbs. Early improvements in the 1940s and 1950s reflected investment during the Truman administration and the Federal-Aid Highway Act of 1956 era, linking to planned beltway interchanges with Capital Beltway projects and regional connectors like US 301. Subsequent widening projects in the 1970s and 1990s responded to commuter flows associated with Fort Meade expansions, Andrews Air Force Base missions, and population growth in Charles County communities such as Waldorf. Safety and capacity upgrades have included interchange reconstructions influenced by standards developed after incidents on arterial highways during the National Highway Traffic Safety Administration expansion and planning by Maryland State Highway Administration.

Major intersections

The highway provides junctions with several principal routes: its southern terminus near Indian Head connects local roads and Potomac River ferry and boat access; intersections with MD 225 and MD 228 serve Charles County traffic to La Plata and Bryantown; connections to US 301 and MD 5 accommodate regional travel toward Southern Maryland and Annapolis; northern interchanges provide access to Joint Base Andrews and merge with the Capital Beltway network at I-495 and I-95 movements near Beltway crossings, terminating at the boundary with District of Columbia where traffic continues via D.C. Route 295 to US 1 and downtown Washington.

Traffic and safety

Traffic volumes on MD 210 vary from moderate rural levels near Indian Head to high commuter counts near Andrews and the Beltway interchange, with peak-hour congestion influenced by Pentagon-area commute patterns and Washington metropolitan area travel. Safety records have prompted improvements after crash clusters typical of arterial highways influenced by heavy vehicle mixes from US 301 freight movements and military convoy operations tied to DoD facilities. Enforcement and engineering efforts have involved the Maryland State Police and Maryland Department of Transportation programs addressing speed, access control, and intersection redesigns using standards from the Federal Highway Administration.

Future plans and improvements

Planned projects focus on capacity, multimodal access, and safety enhancements coordinated by the MDOT and Maryland State Highway Administration with input from county planners in Charles County and Prince George's County. Proposals include interchange modernization influenced by Capital Beltway congestion mitigation studies, transit-supportive improvements linked to WMATA and commuter bus services, and active-transportation additions aligning with National Environmental Policy Act reviews and Clean Air Act regional planning. Funding and phasing draw on federal programs such as the Infrastructure Investment and Jobs Act and regional grants administered through Metropolitan Washington Council of Governments, with stakeholder coordination involving Joint Base Andrews and community advocates in Waldorf and Suitland.
