This was the first steel tied through arch built in Illinois. It was built for a new bypass routing of US 66 around Joliet. In 1957, US 66 was rerouted again, onto a new alignment to the west that would eventually become I-55, and this route was made IL 129, carrying only light local traffic. A 1994 inspection showed that the bridge had been allowed to deteriorate so badly that it was closed to traffic. After attempts to sell it failed, it was demolished in 2000.
