Bridge Documentation

View Archived National Bridge Inventory Report - Has Additional Details and Evaluation

This bridge is a four panel half-hip Pratt pony truss with pinned connections. The deck of the bridge is wooden, and the railings are channel railings that appear to be original. Some of these railing sections have fallen of or are partially broken off. The bridge is interesting because it has lattice on the top of the top chord and end posts, an uncommon detail which looks more attractive than the typical cover plate, and while perhaps not as strong, was more resistant to the effects of pack rust over time. The underside of the top chord and end posts have battens. The verticals on the bridge are latticed also. This bridge has been closed to traffic suggesting that Iroquois County plans to let the bridge rot away. A resident near this bridge told HistoricBridges.org that the county was short on money, which is typical of a rural county. These bridges are not necessarily present in the county because someone cares about them, sometimes lack of money actually saves historic bridges for a brief time! However, it is hard to tell that the county is short of money because elsewhere the county has been systematically destroying all its remaining truss bridges and replacing them with costly new bridges. Perhaps this unrestrained demolition of our nation's transportation heritage is leading to the county's limited funds.
