Bridge Status: This bridge is at severe risk for collapse due to deteriorating caissons!
This is an extremely old and very rare example of a pin-connected Baltimore truss, also noted for its unusual design details. It has been long abandoned. The steel around the caissons for the bridge has deteriorated. In fact, there is a huge hole in the side of one of the caissons. The failure of a caisson will result in the total collapse of the bridge, thus this bridge is at severe risk for collapse. This bridge is among the oldest surviving bridges in Illinois, and the truss configuration is extremely rare among highway bridges. The bridge also has very unusual design of its built-up beams.
