This continuous deck truss features a main Baltimore deck truss span and approach spans using a Warren truss configuration. The bridge features mostly riveted connections, although some connections are pinned. The views of the bridge seen on this website are from the north side of the river, and show the approach spans, with the main span in the distance. Photos from HAER show the other end of the bridge. This bridge was a source of pride for U.S. Steel and the American Bridge Company who built it with someone uncommon continuous design to showcase their skill with new silicon steel and push their company and railroad. Today, the bridge remains a large and unusual example of continuous deck truss construction.
The other bridge seen in these photos is the PA Turnpike Bridge.
