Maryland Route 800

Maryland Route 800 (MD 800) is a collection of state highways in the U.S. state of Maryland. The longest section of MD 800, officially MD 800D and known as Watson Lane, is signed and runs 1.57 miles (2.53 km) between two intersections with MD 75 near the unincorporated village of Linwood in western Carroll County. The multiple segments of MD 800 are sections of old alignment of MD 75 between Union Bridge and New Windsor. MD 75 was originally constructed through Linwood in the early 1920s. MD 800 sections were assigned after MD 75 was relocated through the area in the early 1960s.
