Visit The Stewartstown Railroad Website

This bridge is an extremely early surviving metal truss bridge, especially one associated with railroad use. It is also one of the few surviving bridges in existence with the patented Keystone columns, used on this bridge for vertical members and end posts.

The bridge trusses today no longer support the railroad line structurally, with a deck plate girder span carrying train loads. As such, the flooring system is missing from the historic bridge. Despite this alteration, the bridge retains a high level of historic significance due to its age and rare design.

The bottom of Keystone columns tended to collect dirt and hold moisture, and as such were susceptible to deterioration in this area. This is indeed the case with this bridge with many areas of complete section loss in this areas. Restoration of the trusses are needed to ensure a long future for this bridge. The bridge is on a railroad line that is owned and operated as a small recreational and historical line. As such, while appreciation for this bridge likely exists with its owner, this largely volunteer-oriented organization may not have the funds to hire even a reasonably priced firm like Bach Steel to restore the trusses properly in a way that respects the original design and materials. Hopefully a funding source can be found for the preservation of these significant trusses.

This bridge is tagged with the following special condition(s): Keystone Columns
