Bridge Documentation

This bridge is an impressive railroad bridge that is noted for its two large spans that are excellent examples of late 19th Century pin-connected railroad trusses. The northern span is one panel longer than the southern span. There are also deck truss approach spans as well as deck plate girder approach spans. There apparently was also a Warren truss approach span which has been demolished and replaced, when the bridge was converted for use by pedestrians. Additionally, a new approach ramp was built at the southern end of the bridge to accommodate the pedestrian usage. The ramp runs eastward up to the level of the original bridge deck, meeting the original bridge deck at a 90 degree angle.

Typical of railroad bridges of this period, the bridge features heavy-duty, massive members, and large numbers of eyebar bundles in many of the bottom chord connections.

The bridge was built by the Pencoyd Bridge and Construction Company, which was part of the the Pencoyd Iron Works.

The bridge is a good example of preservation and reuse of a historic railroad truss bridge.
