US 50 serves as the main route between the Baltimore–Washington Metropolitan Area and the Eastern Shore, providing access to Ocean City and, by way of MD 404 and Delaware Route 404 (DE 404), the Delaware Beaches. As such, the route experiences heavy traffic in the summer months, with major congestion points including the Pearl Harbor Memorial Bridge over the Severn River in Annapolis, the Chesapeake Bay Bridge toll plaza, Easton, Cambridge, and the few miles leading into Ocean City. The peak travel periods in the summer are eastbound on Friday evenings, both directions on Saturday afternoons, and westbound on Sunday afternoons. The route is also a designated hurricane evacuation route out of Ocean City. US 50 in Maryland is a part of the main National Highway System between the Washington, D.C. border and the eastern terminus in Ocean City.
