Maryland Route 309

Maryland Route 309 (MD 309) is a state highway in the U.S. state of Maryland. The state highway runs 18.50 miles (29.77 km) from U.S. Route 50 (US 50) in Easton north to MD 213 south of Centreville. MD 309 is a C-shaped highway that passes through northeastern Talbot County and southeastern Queen Anne's County, connecting Easton and Centreville with Queen Anne, where the highway intersects MD 404. MD 309 was originally designated along the highway between Easton and Queen Anne. The highway was constructed south from Queen Anne to Cordova in the late 1920s along MD 303's current course and from Cordova to Easton in the early 1930s. In 1955, MD 309 gained its northern segment by assuming MD 303, which originally followed the Queen Anne–Centreville portion of the present MD 309. When MD 309 moved to a new alignment between Cordova and Queen Anne in the early 1960s, MD 303 was assigned to the old alignment.
