History

This new tunnel had a height of, lower than the main tunnel. The southern end was again extended around 1900 to add a sidewalk to the road. This extension lowered the height of the tunnel to the current.

Light Rail

The tunnel and the adjacent Panhandle Bridge were purchased by the Port Authority from Conrail for $8.15 million in 1980. The tunnel is now utilized by the Pittsburgh Light Rail System for some of its right-of-way and the Steel Plaza Station.
