The bridges are post tensioned cast-in-place concretebox girder bridges.
Each bridge has two lanes of travel on a 39-foot deck. The bridge has roughly 7,500 travelers per day.
History
The bridges were completed in 1988. The highway was not completed until 1992, when Highway 36 was rerouted onto I-72 and the older Florence Bridge began carrying Illinois Routes 100 and 106.
