About: Maryland Route 808

Maryland Route 808 (MD 808) is a state highway in the U.S. state of Maryland. Officially MD 808A and known as Main Street, the state highway runs 2.34 miles (3.77 km) from Ridgeville Boulevard north to MD 27 within Mount Airy. MD 808 follows the Carroll–Frederick county line for a portion of its length near its southern terminus. The county line portion is considered to be in Carroll County for maintenance purposes. MD 808 is the old alignment of MD 27 through Mount Airy. A portion of Main Street was paved by 1910; the sections south and north of the town center were constructed in the early 1910s and late 1910s, respectively. MD 808 was assigned to Main Street after MD 27's bypass of Mount Airy was completed in the mid-1970s.
