The Borden Tunnel is a 957-foot formerly abandoned railway tunnel located about 2.5 miles (4 km) north of Frostburg, Maryland. Unlighted, it is now part of the Great Allegheny Passage rail trail.[1][2]
The Western Maryland Railway built the tunnel in 1911 for its Connellsville Subdivision. The rail line was abandoned in 1975.[3]
