Maryland Route 425
MD 425 begins at an intersection with MD 6 (Port Tobacco Road) south of the community of Nanjemoy and north of the hamlet of Grayton. The state highway heads northeast as two-lane undivided Ironsides Road through a forested area, passing Baptist Church Road and crosses a branch of Hill Top Fork of Nanjemoy Creek. At Durham Church Road, MD 425 makes a 90-degree turn to the north and intersects MD 6 again in the village of Ironsides. The state highway continues north as Mason Springs Road, crossing Jane Berrys Run. MD 425 intersects Bicknell Road and Poorhouse Road in the hamlet of Pisgah and passes the historic home Araby before reaching the highway's northern terminus at MD 224 (Chicamuxen Road) in Mason Springs. The first section of MD 425 was constructed as a gravel road south from Mason Springs in 1930. The highway was extended south another through Pisgah in 1933. Also in 1933, of gravel road was constructed from the Nanjemoy end. This segment was originally designated MD 491. MD 425 was extended with another section in 1934. The courses of MD 425 and MD 491 remained the same until 1950 when MD 425 was extended south to Ironsides and MD 491 was extended north to Ironsides. MD 425 was extended south to Nanjemoy, assuming MD 491's entire course, in 1956.
