Maryland Route 564
State highway in Prince George's County, Maryland, US
Maryland Route 564 (MD 564) is a state highway in the U.S. state of Maryland. Known for most of its length as Lanham Severn Road, the state highway runs 6.73 miles (10.83 km) from MD 450 in Lanham east to a dead end near a connection to MD 197 in Bowie. MD 564 was constructed from Lanham to Old Town Bowie in the mid-1930s. In the early 1990s, the highway was extended east over part of MD 197 when that highway was relocated through Bowie.
Route description
MD 564 begins at a partial interchange with MD 450 (Annapolis Road) in Lanham. There is no access from westbound MD 450 to eastbound MD 564 or from westbound MD 564 to eastbound MD 450. Eastbound MD 564 exits from eastbound MD 450, passes under MD 450, and meets westbound MD 564 at an intersection where heading straight leads to Cipriano Road. The two directions of MD 564 come together as Lanham Severn Road, a two-lane undivided road heading northeast paralleling Amtrak's Northeast Corridor railroad line and MARC's Penn Line at a distance. The state highway crosses Baldhill Branch and passes through the unincorporated community of Seabrook, where the road intersects Seabrook Road and passes the Seabrook station serving MARC trains. After passing through a commercial area in Seabrook, MD 564 passes several industrial properties on the railroad side of the highway.
