The Borden Tunnel is a 957-foot long, formerly abandoned, railway tunnel located about 2.5 miles (4 km) north of Frostburg, Maryland. The tunnel is lit with a series of motion activated LED lights powered by a solar panel located just north of the tunnel. 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.
