The longer of these serves as a major route connecting Washington, D.C., with Ocean City; the latter is the eastern terminus of the highway. The other section passes through the southern end of Garrett County for less than 10 miles (16 km) as part of the Northwestern Turnpike, entering West Virginia at both ends. One notable section of US 50 is the dual-span Chesapeake Bay Bridge across the Chesapeake Bay, which links the Baltimore–Washington metropolitan area with the Eastern Shore region, allowing motorists to reach Ocean City and the Delaware Beaches.

The highway was widened in the early 1940s, then became MD 554 in a number swap with the Severn–Odenton portion of MD 170. MD 174 was constructed in the early 1920s as a short road from MD 3 in Glen Burnie west to the site of the highway's modern Interstate 97 (I-97) interchange.

The first modern highway from Cape St. Claire to Skidmore was constructed in the late 1920s and replaced by the modern alignment of US 50 in the late 1940s. The frontage roads on either side of the U.S. Highway were constructed in the early 1950s. The mainline segments of MD 908 assumed their present form when US 50 and US 301 were upgraded to a freeway in the early 1990s.
