Bridge Documentation

This is one of the most unique truss bridges ever encountered. It is an almost unheard of design... a through Kingpost truss. Nearly all metal Kingpost truss bridges are pony truss bridges. The whole idea of a Kingpost was a solution for short-span bridges, while through truss bridges were a solution for longer spans. So to combine a truss configuration normally used for short spans with an overhead bracing "through" design intended for longer trusses is quite unusual. The bridge's overhead bracing is an unusual pipe design. Decorative circular knee braces are present on the bridges overhead bracing as well. Another unusual feature is the use of v-lacing on top of the end post instead of cover plate.

The builder of the bridge is unknown. Some claim that Horace Horton of the Chicago Bridge and Iron Company built it, but HistoricBridges.org was not able to confirm these speculations.

This bridge has been bypassed by a realignment of the road. It has been left standing in an abandoned condition. The approaches have been removed. This is one of the most unique truss bridges in existence. The timber piles it currently rests on do not look like they will last forever. It would be nice to see this bridge relocated and preserved in a new location.
