This project is a 15-mile interstate reconstruction project in the westbound lanes of I90 in McCook County. Two bridges and one box culvert will be removed and replaced, and two other bridges will be resurfaced.
The purpose of the project is to improve the condition of the roadway surfacing and replace bridge structures due to age.
Roadway reconstruction is scheduled to be completed by November 18, 2022, with final striping to occur in the spring of 2023 with completion by June 2023.
May 31, 2023:
May Completed Work: The contractor was working on the remaining punch list/general cleanup items.
Anticipated Work in June: The contractor intends to complete all remaining cleanup work by June 16, 2023.
May 1, 2023:
April Completed Work: The Contractor completed the bridge girder connection modifications. Wet conditions prevented the contractor from doing most of the remaining work items.
Anticipated work in May: The Contractor is planning to mobilize in during the week of May 8 to start all remaining project work. The contractor will be using a combination of shoulder closures and single lane closures to allow work to be completed while safely getting traffic through the work zones.
November 30, 2022 Nov. 30, 2022: On Thursday, Dec. 1, 2022, a significant traffic switch will occur. Motorists are advised that all westbound traffic will be moved from the eastbound lanes and guided into the westbound lanes so repainting of lane lines can be completed for eastbound traffic.
Eastbound lanes are scheduled to be repainted on Thursday, Dec. 1, 2022, and Friday, Dec. 2, 2022. When completed, two-way traffic control measures will be removed and eastbound and westbound traffic will be fully operational. Motorists should be aware that some temporary lane closures may still be in place during project clean-up work.
All exits along this reconstruction project will be reopened both eastbound and westbound; once traffic is switched. As originally scheduled, shoulder work and final striping will be completed in spring 2023.
Since the project began in March 2022, two-way traffic has been used in the eastbound lanes during the reconstruction of the westbound lanes. Work on the 15-mile Interstate reconstruction project included recycling the existing surfacing, placement of 11 ½ inches of new concrete surfacing with asphalt shoulders, reconstruction of two bridges, rehabilitation of two additional bridges, replacement of culverts, and regrading of low-lying areas.
