Superstructure replacement and bridge widening of 2 structures on I-57 over IC Railroad and TR 86 at Jones Switch

The Illinois Department of Transportation (IDOT) is requesting bids for superstructure replacement and bridge widening of two structures on Interstate 57 over the Illinois Central Railroad and Township Road 86 at Jones Switch in Coles County, with electronic bids due June 12, 2026 at noon via the iCX system.

The scope includes removal and replacement of existing bridge decks and superstructures on structures SNs 015-0003 (southbound) and 015-0004 (northbound), substructure widening to accommodate proposed improvements, approach slab and shoulder removal, diamond grinding and surface testing, slipform parapet construction, concrete headwall installation for pipe drains, temporary lighting systems, real-time traffic control systems, and removal and disposal of regulated substances. The work is sequenced across four stages: median crossover and pre-stage construction, pre-stage deck patching, stage 1 reconstruction of one bridge, and stage 2 reconstruction of the second bridge. Utility coordination with Ameren Electric and Gas, fiber optic providers, water services, and telecommunications is required. The contract involves cooperation with an adjacent concurrent IDOT contract (74435) for I-57/Illinois 16 bridge replacement, requiring coordinated traffic control setup and operations between contractors.

Traffic control restrictions prohibit certain lane closures between November 15 and March 1, and between December 1 and March 1. The project completion date is April 30, 2027, with an allowance of 15 guaranteed working days for cleanup and punch list items. The contract will be awarded to the lowest responsive and responsible bidder conforming to IDOT terms and conditions. This is a federal-aid construction project; detailed special provisions address traffic control standards dependent on construction phases and proximity to edge of pavement.
