The Illinois Department of Transportation is requesting bids for bridge deck replacement on Illinois Route 23 (Structure Number 053-0149) in Livingston County, a 5-span structure crossing the Vermilion River and BNSF railroad 0.8 miles south of the LaSalle County Line, with electronic bids due June 12, 2026 at 12:00 p.m. to the iCX system.

The scope includes complete bridge deck replacement, bearing replacement, substructure repairs, full superstructure painting, and pavement work north of the bridge (removal and replacement to address settling) and south of the bridge (milling and resurfacing). Utility coordination has been completed with no anticipated conflicts identified from Buckeye Partners, ComEd, Frontier Communications, Illinois American Water, Mediacom, Metro Communications, Nicor, and Reading Township. Contractors must obtain Railroad Protective Liability Insurance and pay for a BNSF Railway Company occupancy permit (estimated at $2,000 as of March 14, 2026, subject to change) and railroad flagging services.

Construction must not begin before May 1, 2027, to avoid staged construction over winter months. The contract will be awarded to the lowest responsive and responsible bidder in conformity with all terms, conditions, rules, and specifications established by IDOT. Special provisions apply, including quality control and quality assurance of concrete mixtures, temporary portable bridge traffic signals with microwave detection, work zone traffic control, and compliance with Corps of Engineers Nationwide Permit #3 for bridge maintenance activities.
