Maryland Route 424 (MD 424) is a state highway in the U.S. state of Maryland. The highway stretches 14.77 miles (23.77 km) from its southern terminus at Maryland Route 2 (MD 2) in Birdsville, Anne Arundel County, to its northern terminus at U.S. Route 301 (US 301) in Queen Anne, Prince George's County.
Predominantly known as Davidsonville Road, MD 424 serves as a vital north-south connector through central Anne Arundel County, linking rural communities with major east-west corridors. The route is maintained by the Maryland State Highway Administration (MDSHA) and is primarily a two-lane undivided highway.
Route Description MD 424 commences at an intersection with MD 2 (Solomons Island Road) in the unincorporated community of Birdsville, in southern Anne Arundel County. From this point, the route proceeds northward through a landscape characterized by agricultural land and low-density residential areas. It intersects with MD 214 (Central Avenue) in Davidsonville, a significant local crossroads. Further north, MD 424 passes over the US 50/US 301 (John Hanson Highway) freeway without a direct interchange, with local roads providing access to the freeway in the vicinity. The highway continues its northerly progression, eventually crossing the county line into Prince George's County for a brief segment before reaching its northern terminus at an intersection with US 301 (Robert Crain Highway) in the community of Queen Anne.
History The initial segment of Maryland Route 424 was constructed in the mid-1920s, providing a state-maintained connection between Birdsville and Davidsonville. As the region developed, the highway was extended northward to intersect with US 50 in the early 1940s, enhancing its role in regional transportation. The final extension to its current northern terminus at US 301 was completed in the late 1950s, establishing the route as it is known today.
