High Quality Content by WIKIPEDIA articles! Maryland Route 64 (MD 64) is a state highway in the U.S. state of Maryland. The state highway runs 13.33 miles (21.45 km) from U.S. Route 40 (US 40) in Hagerstown east to the Pennsylvania state line near Ringgold, where the highway continues as Pennsylvania Route 997 (PA 997). MD 64 is an L-shaped route in northeastern Washington County, connecting Hagerstown with Smithburg, Cavetown, and Chewsville and Smithsburg with Ringgold and Waynesboro, Pennsylvania. The state highway is maintained by the Maryland State Highway Administration except for the municipally-maintained portion within the city limits of Hagerstown. MD 64 was once a turnpike between Hagerstown and Smithsburg. The state highway was constructed from Smithsburg to the Pennsylvania state line in the mid 1910s and from Hagerstown to Smithsburg in the early 1920s. MD 64 was reconstructed in its entirety in the 1950s, resulting in bypasses of all four communities east of Hagerstown the highway serves.
