About this opportunity
The Illinois Department of Transportation is requesting electronic bids for removal and replacement of two box culverts on IL 142 in St. Clair County near Eldorado, with bids due September 18, 2026 at 12:00 p.m. through the iCX-Integrated Contractors Exchange system. Contract 78A98 is funded through Federal-aid Construction (project STP-KSGV(288)) administered by IDOT District 9.
The scope includes removal of existing box culverts SN 083-7053 and SN 083-7054 and replacement with precast concrete box culverts (designated SN 083-7110 and SN 083-7111) during weekend closures using a state route detour. Associated work comprises porous granular embankment, stone riprap, concrete pavement, concrete shoulders, pavement marking, earthwork, and seeding. SN 083-7110 requires cast-in-place concrete horizontal wingwalls on the south end and a cast-in-place concrete end section on the north end. SN 083-7111 requires cast-in-place concrete horizontal wingwalls on the north end and a cast-in-place concrete drop structure on the south end. One lane of traffic on IL 142 will be maintained over both structures during construction of cast-in-place end sections.
Precast concrete box culvert sections must be pre-assembled and match-marked before jobsite delivery. IL 142 must remain open to at least one lane except during permitted weekend closures. Closure of Grayson Road is authorized for up to 45 days; liquidated damages of $5,000 per day apply if reopening does not occur within the specified timeframe. Changeable message signs must be placed a minimum of 14 calendar days prior to closures. Contractors must coordinate with Ameren Illinois (gas and electric), Eldorado Water Department, and multiple communications providers. Calcium chloride accelerator is permitted only for proposed PCC pavement. All work must comply with IDOT Standard Specifications for Road and Bridge Construction (effective January 1, 2022, revised January 1, 2026), supplemental specifications, and recurring special provisions. The contract will be awarded to the lowest responsive and responsible bidder.
