The tunnel was used to allow trains on the Pittsburgh and Lake Erie Railroad to bypass the Jones and Laughlin steel mill, by passing under it.
Starting in 2011,[5] work was performed, as part of CSX Transportation's National Gateway project, to raise the clearance inside the tunnel, allowing double-stacked container trains to pass through the tunnel.[3]
Above the tunnel is a small park called Tunnel Park.[6]
