Maryland Route 68
State highway in Washington County, Maryland, US

Maryland Route 68 (MD 68) 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 40 (US 40) in Clear Spring east to US 40 Alternate in Boonsboro. MD 68 crosses central Washington County to the south of Hagerstown, connecting Clear Spring and Boonsboro with Williamsport, where the highway runs concurrently with MD 63. A small segment of MD 68 west of Boonsboro was constructed around 1920, using as part of the route two early 19th-century stone bridges. The remainder of the highway between Boonsboro and Williamsport was constructed in the second half of the 1920s. MD 68 was extended west from Williamsport to Clear Spring in the mid-1950s. The state highway was relocated south of Williamsport for the construction of Interstate 81 (I-81) in the mid-1960s. Since the early 1990s, I-68 has also existed in Washington County; signs on I-70 aim to avoid confusion between I-68 and MD 68.
