Maryland Route 332 (MD 332) is a state highway in the U.S. state of Maryland. Known for most of its length as Central Avenue, the highway runs 1.07 miles (1.72 km) from Southern Avenue at the District of Columbia boundary in Capitol Heights east to MD 214 in Seat Pleasant. MD 332 is the old alignment of MD 214 through Capitol Heights. The highway was constructed in the mid-1910s and bypassed when East Capitol Street was extended east out of Washington, D.C. to Seat Pleasant in the late 1960s.
