Frontage Road North and South Between Cass Ave and Clarendon Hills Rd.
Weather-permitting, the contractor has worked through the winter on the I-55 North and South Frontage Roads, removing and installing new culverts. On the S. Frontage Rd. they are currently backfilling and work is estimated at 70% complete. Due to additional utility relocations, the contractor is still working on culvert installation on N. Frontage Rd. and work is estimated at 25% complete. Pending suitable weather conditions and no additional conflicts, project completion is anticipated early June 2025.
