The Whitehall Tunnel in Allegheny County, Pennsylvania was originally built by the B&O Railroad in 1899 as a double-track tunnel.[1] The tunnel was completed in 1900.[2] It was part of the Baltimore and Ohio Short Line Railroad, and allowed the B&O to bypass its former route into Pittsburgh along the Pittsburgh Southern and Little Saw Mill Run Railroad.[3] One worker, Antonio De Bono, was killed during its construction.[4]

It is currently a single-track tunnel, owned by the Allegheny Valley Railroad. The tunnel is approached from Glenwood in the south, up a steep grade along the Streets Run valley to the northern end of the tunnel. The line continues from the southern end to Bruceton, Pennsylvania.
