Bridge Documentation

This bridge no longer exists!

Bridge Status: This historic bridge was demolished in 2020!

This bridge was originally built as a three span pin-connected through truss bridge, reportedly in 1897. At some point in its history, likely in the first decades of the 20th century, something happened to the western span and it was replaced with a riveted through truss span with details typical of a ca. 1910-1930 truss. All three spans should be considered to have historic value today.

Bypassed and abandoned, this regionally rare multi-span pin-connected truss bridge with a riveted truss span as well was sentenced to the dumpster thanks to a lack of vision. The reason for the demolition was becuase one of the stone piers is deteriorating. Rather than spend the $476,784.03 on repairing the pier, the county chose to spend that money to wipe this bridge off the face of the earth. This represents a waste of heritage and a waste of money! What is sad, is the fate of this bridge was decided by the Kendall County Forest Preserve Commission. What is the purpose of the Forest Commision? Recreation and preserving natural areas, which this bridge greatly complimented. This bridge was located near to a canoe launch. What will people paddling down the Fox River admire now? The ugly slab of concrete that carries Whitfield Road today? This bridge was a centerpiece attraction for recreation on the river. It is shameful that such a rare bridge was so carelessly discarded by an agency that has as its goal the bettering of recreational opportunities for people in the area. On top of this, it appears this is the last remaining truss bridge of any kind in the county. Thanks to this horrible decision, Kendall County will earn the dubious distinction of becoming a "trussless" county, which indicates a failure to preserve even a single historic metal truss bridge.
