Maryland Route 67 (MD 67) is a state highway in the U.S. state of Maryland. Known as Rohrersville Road, the state highway runs 12.20 miles (19.63 km) from U.S. Route 340 (US 340) in Weverton north to US 40 Alternate in Boonsboro. MD 67 parallels the western flank of South Mountain in southeastern Washington County, connecting Boonsboro with Weverton and Rohrersville. In conjunction with US 340 and US 40 Alternate, MD 67 connects Hagerstown and Harpers Ferry, West Virginia, a link that made the highway one of the original state roads marked for improvement in 1909. The first section of the state highway was constructed through Rohrersville around 1920. The remainder of the highway was built between Boonsboro and Weverton in the late 1920s and early 1930s. MD 67 was reconstructed with multiple relocations starting in the late 1950s, culminating in a relocation at the southern terminus to tie into the US 340 freeway in the late 1960s. (Full article...)
