This is a Federal-Aid construction contract subject to DBE participation requirements and prevailing wage compliance.

The contract incorporates the Standard Specifications for Road and Bridge Construction (Adopted January 1, 2022, Revised January 1, 2026), supplemental specifications, and project-specific special provisions addressing construction layout, traffic control, materials testing, and quality assurance. The contractor must complete all work and open the roadway to traffic by November 24, 2027, operating under an expedited construction schedule with staged phases beginning as early as April 1, 2027. Extensive traffic control measures apply, including long-term shoulder closures, up to sixteen calendar days of complete nighttime lane closures (10:00 p.m. to 5:30 a.m.) for beam removal and replacement, and full closure of Closen Road during demolition and reconstruction with detour routes per plan details.

The award will be made to the lowest responsive and responsible bidder. IDOT reserves the right to determine contractor responsibility at the time of award and to reject any or all bids. Bids will be publicly opened from the iCX SecureVault immediately after the deadline. Construction funding is identified as Construction Funds through IDOT District 4.
