Advisory: Southbound Madison Street closed May 10th-June 30th
Constructed in 1959 and carrying over 142,000 vehicles per day, the I-55 bridge is one of the worst-rated in the State’s highway system. Exposed reinforcing steel and corroded bridge piers are obvious from underneath. Design of the project began in early 2020, repairs atop I-55 were completed in 2021, but bridge pier patching has been delayed since 2022. IDOT cannot postpone the project any longer and stated that its work begins on May 10th.
