Tom Callahan, owner of the Lockport, New York, Cave and Underground Boat Ride, has found evidence in the National Archives that the well-known upside-down railroad and foot bridge that crosses the old Erie Canal near the five step locks was built by the King Bridge Company in 1902 for the New York Central Railroad. The evidence is contained in the pre-inventory field notes conducted by the NYCRR in 1919. This historic bridge is composed of three spans of very different characteristics. The main span of 182 feet is a deck lattice structure of a design similar to that shown in one of the early King Bridge Company catalogues of the 1880s attributed to the company's then chief engineer, William Vliet. The other spans are a shorter deck truss of 129 feet and a beam girder of 80 feet. 

The bridge is currently owned by the Genesee Valley Transportation Company and is used for occasional freight and scenic excursion trains.  A local group is trying to rehabilitate the footbridge portion of the structure, which has traditionally been one of the best places in Lockport to view the world famous canal and its locks. Along with the Hojack Swing Bridge in Rochester, this bridge is a fine example of the work the King Bridge Company undertook for the nations railroads to find creative engineering design and construction solutions for crossing strategic waterways. It is also one of the most important of the remaining bridges built by the company in upstate New York.
