Most People Have No Idea This Unique Tunnel In Oklahoma Exists

Jenson Railroad Tunnel, located in LeFlore County, is the first and only railroad tunnel in Oklahoma. It was built through Backbone Mountain during the mid 1880s in Indian Territory by the Fort Smith & Southern Railway. It is still in operation today, primarily used by the Kansas City Southern Railroad. The tunnel is 1,180 ft. long and has a single track running through it. The tunnel was listed on the National Register of Historic Places on May 13, 1976.

The tunnel is located on private property – owned by the KCS railroad. Please remember to use caution, as the tunnel is still in operation for trains today.
