The Illinois Department of Transportation is soliciting bids for replacement of box culvert SN 028-7068 on Illinois Route 149 over the Green River in Franklin County, approximately 2 miles west of West Frankfort, with electronic bids due September 18, 2026 by 12:00 p.m. in the iCX system. A 5.00% Disadvantaged Business Enterprise participation goal applies, requiring bidders to demonstrate good faith efforts to meet this threshold.

The scope requires removal of the existing 10 ft × 6.5 ft single barrel box culvert and replacement with a 12 ft × 8 ft single barrel box culvert (60 ft length out to out of headwalls, no skew). Work includes culvert removal and replacement, backfill, pavement work, traffic control, detour signing, waterproofing membrane systems, and appurtenances. The project must maintain Illinois Route 149 open to at least one lane of traffic at all times, with allowance for a single weekend closure (Friday 6:00 p.m. through Monday 6:00 a.m.) for culvert removal and replacement. Failure to reopen by 6:00 a.m. Monday triggers a traffic control deficiency penalty of $5,000 per day. Utility coordination is required with Frontier Communications, Key Rock Energy, Marathon Pipeline, Plumfield Water District, and Protek Communications; utility adjustments are anticipated for telephone/fiber optic, gas pipelines, and water lines.

The contract is funded through Federal-aid Highway funds (NHPP-E8PF(297)) and is subject to 49 CFR Part 26 DBE compliance requirements and all state and federal terms. The award goes to the lowest responsive and responsible bidder.
