Maryland Route 50 (state) is a primary state highway running east–west across Maryland, from the border with Washington, D.C. to Ocean City on the Atlantic coast. The route connects the Capital Beltway, the Baltimore–Washington Parkway, Annapolis, the Chesapeake Bay Bridge, and coastal resort destinations, passing through both suburban and rural landscapes. As a major arterial, it interfaces with the I-95 corridor, links to U.S. Route 50 continuations, and serves commuter, tourist, and freight traffic.

Route description

Maryland Route 50 begins at the District of Columbia boundary near New York Avenue and proceeds northeast as a multilane arterial, intersecting with MD 410, Connecticut Avenue and providing access toward US 1 and I-495. The highway traverses Prince George's County and passes near College Park, the University of Maryland campus, and connects with MD 193 and MD 450. Entering Anne Arundel County, the route skirts Baltimore/Washington International Thurgood Marshall Airport and intersects the Baltimore–Washington Parkway and I-97 corridors near Annapolis and Parole. In the Annapolis area, MD 50 merges with limited-access freeway sections, linking to MD 2 and providing access to the United States Naval Academy. Crossing the Chesapeake Bay Bridge—officially connecting Anne Arundel County and Queen Anne's County—the route descends into the Eastern Shore, passing near Queenstown and Easton. Continuation eastward traverses Cambridge and Salisbury, intersecting US 13 and US 113 before terminating on Worcester County at Ocean City, near the boardwalk and beachfront resort facilities.

History

The corridor that became Maryland Route 50 originated from early 20th-century turnpikes and state roads connecting Washington, D.C., Annapolis, and the Eastern Shore. In the 1920s, state highway numbering formalized MD 50 as part of Maryland's expanding highway system during the era of Good Roads Movement influences and federal road legislation. The mid-20th century saw significant upgrades: the construction of bypasses around Annapolis and limited-access segments to accommodate growth tied to postwar suburbanization, the rise of BWI Airport, and the development of Interstate connections. The opening of the Chesapeake Bay Bridge transformed MD 50 into a primary transbay link, spurring tourism and commercial traffic to Ocean City and resort communities. Later decades featured widening projects, interchange reconstructions with I-95 and US 13, and safety improvements prompted by incidents and seasonal congestion associated with Memorial Day and Fourth of July travel to coastal destinations.

Major intersections

Major interchanges and junctions along MD 50 include its western terminus at the Washington, D.C. line and connections with I-495, Baltimore–Washington Parkway, MD 450, MD 2, MD 665 (access to Annapolis), the Chesapeake Bay Bridge, Queenstown area junctions, US 50 concurrency segments, intersections with US 13 at Salisbury, US 113 toward Berlin and Ocean City, and its eastern terminus in Ocean City near Route 528 and the Assateague Island National Seashore access corridors. The highway also interfaces with state routes serving regional centers such as MD 404 and MD 312.

Auxiliary routes

Auxiliary and spur routes associated with MD 50 include business loops and connectors serving Annapolis, Queenstown, and Salisbury, as well as numbered suffixed segments used for short linkages to local arterials and park-and-ride facilities. Designations historically included branches and former alignments turned over to county maintenance serving communities such as Crofton, Severn, and Queen Anne. These auxiliary segments facilitated access to institutions including the United States Naval Academy, the University of Maryland, and regional airports like Salisbury–Ocean City–Wicomico Regional Airport.

Traffic and usage

MD 50 carries a varied mix of commuter traffic from Prince George's County suburbs, service traffic to BWI Airport, military-related flows to the United States Naval Academy and Fort Meade, and seasonal tourist volumes bound for Ocean City and Atlantic coast beaches such as Assateague Island. Peak seasonal congestion correlates with holiday periods tied to Memorial Day and Independence Day tourism. Freight movements utilize MD 50 as part of east–west corridors linking interstate routes such as I-95 and coastal US routes like US 13, affecting pavement wear and prompting targeted maintenance by the Maryland State Highway Administration and county highway departments.

Future developments and improvements

Planned projects for MD 50 have focused on interchange modernization near Annapolis and Parole, bridge maintenance and capacity assessments for the Chesapeake Bay Bridge, safety enhancements where MD 50 intersects US 13 and US 113, and multimodal improvements to better serve transit connections to BWI Airport, Metro corridors, and regional bus operators including Maryland Transit Administration. Studies involving corridor widening, intelligent transportation systems, and resilience measures against coastal storms and sea-level rise have been considered in coordination with Queen Anne's County, Worcester County, and federal agencies that oversee coastal infrastructure and environmental impact assessments.
