Bridge Documentation

This bridge no longer exists!

The Pressed Steel Car Company had the Preston Foot Bridge built to provide a connection to their company town called Preston.

This multi-span structure is a rare example of a historic truss bridge that was built for pedestrian use only. It features several original Pratt through truss spans that are quite tall for pedestrian bridges, and a riveted Warren through truss span that is shorter in terms of height, and appears to be a replacement span, but it is also riveted and should be considered historic along with the older spans. There also are many pony truss approach spans, which during the summer are very overgrown with vines.

Pedestrian truss bridges often have unusual dimensions to them, most notably less vertical clearance that makes them unusually short. This however is not the case with the original spans, which are tall and have the shape of perhaps a narrow railroad bridge. The newer span however does have this unusual shape, and is very short. To anyone who has visited a lot of vehicular truss bridge, one might feel like they are giants as they cross this span.

The bridge is today abandoned and not in use. It is owned by the railroad.


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