Maryland Route 194 (MD 194) is a state highway in the U.S. state of Maryland. The state highway runs 23.87 miles (38.42 km) from MD 26 in Ceresville north to the Pennsylvania state line near Taneytown, where the highway continues as Pennsylvania Route 194 (PA 194) toward Hanover. MD 194 is the main highway between Frederick and Hanover; the state highway connects the towns of Walkersville and Woodsboro in northeastern Frederick County with Keymar and Taneytown in northwestern Carroll County. MD 194 was blazed as a migration route in the 18th century and a pair of turnpikes in Frederick County in the 19th century, one of which was the last private toll road in Maryland. The state highway, which was originally designated MD 71, was built as a modern highway in Frederick County in the mid-1920s and constructed as Francis Scott Key Highway in Carroll County in the late 1920s and early 1930s. MD 194 received its modern route number in 1956 as part of a three-route number swap. The state highway's bypasses of Walkersville and Woodsboro opened in the early 1980s and mid-1990s, respectively.
