Infrastructure Update: I-88 bridge repairs over the Hennepin Canal begin Aug. 2

The Illinois Department of Transportation announced today that weather permitting, repairs to the bridges carrying Interstate 88 across the Hennepin Canal in Rock Falls in Whiteside County will begin on Monday, August 2, 2021. The bridges are just west of the Illinois 40 interchange (exit 41).

Work will involve deck patching, expansion joint replacement, concrete overlay installation and structure repairs. One lane in each direction will be closed during the $1,444,157 project, which Civil Constructors Inc. of Freeport is the contractor. Work is expected to be completed by November 4.

Motorists can expect delays and should allow extra time for trips through this area and be prepared for slow and stopped traffic. To avoid the work area, when feasible, use of alternate routes should be considered. Drivers are urged to pay close attention to changed conditions and signs in the work zones, obey the posted speed limits, refrain from using mobile devices and be alert for workers and equipment.
