About: Maryland Route 424

Maryland Route 424 (MD 424) is a state highway in the U.S. state of Maryland. Known as Davidsonville Road, the highway runs 8.24 miles (13.26 km) from MD 214 in Davidsonville north to MD 3 in Crofton. MD 424 connects U.S. Route 50 (US 50)/US 301 with the two communities in central Anne Arundel County. The highway was constructed from Davidsonville to what is now MD 450 in the late 1920s. MD 424 was extended to what is now MD 3 in the late 1940s. The highway's interchange with US 50 opened in the early 1950s when the U.S. Highway was relocated between Bowie and Annapolis. MD 424 temporarily extended south to MD 2 in the early to mid-1950s and north to the Little Patuxent River in the 1970s and early 1980s.
