MD 562 begins as Old York Road at its intersection with Markoe Road. Old York Road continues south as a county highway to MD 145 in Jacksonville. The state highway heads north through farmland. MD 562 veers northwest onto Troyer Road as Old York Road continues north as a county highway toward MD 23 in Shawsville. The state highway reaches its terminus at a T-intersection with MD 138, which continues north as Troyer Road and heads west as Sheppards Road to the hamlet of Monkton.
Old York Road was an alternate, less-direct route for traffic between Towson and Maryland Line compared to York Road, which is now MD 45. MD 562 is part of one extant stretch of the road; another segment is MD 439 from Shawsville to Maryland Line. The Troyer Road section of MD 562 was constructed as a concrete road in 1933. The Old York Road segment of MD 562 was built as a macadam road in 1934. The state highway has changed very little since the 1930s.
The entire route is in Monkton, Baltimore County.
