Overview and Scope
The I-90/Kennedy Expressway feeds directly into O’Hare International Airport and is a core local expressway moving traffic in and around the city. Its bridge structures provide support to 275,000 vehicles per day, including personal vehicles and freight trucks.
These structures are more than 50 years old and were last repaired in 2012. Since then, the decks have begun to show signs of deterioration and the 2012 repairs have reached the end of their intended lifespan. IDOT is now planning to make long-term improvements to improve the condition of the mainline Kennedy Expressway structures to help ease maintenance and ensure their continual service.
A project area boundary has been defined adjacent to the bridge locations that encompasses various community and environmental resources. The overall project area and bridge locations are shown in the map below.
The I-90/Kennedy Expressway varies throughout the project area and includes:
- Four lanes inbound and outbound
- Two reversible lanes
- Multiple on and off ramps at interchanges
- Auxiliary lanes between interchanges
- Restricted shoulder widths due to overpass structures and the densely developed urban area
The projected benefits of the project include:
- Improved Infrastructure
- Structural Safety
- Reduced Maintenance Costs
- Reduced Impacts to Traffic During Maintenance
Details
IDOT develops and implements projects using the following three-phase process:
- Phase I: Preliminary Engineering and Environmental Studies. The I-90/Kennedy Expressway Bridge Rehabilitation Project has completed Phase I in 2021.
- Phase II: Contract Plan Preparation. The I-90/Kennedy Expressway Bridge Rehabilitation Project is currently in Phase II and completion of Phase II Contracts is anticipated in 2022 (Typically 18-24 months)
- Phase III: Construction and Construction Engineering (Typically 12-24 months)
This improvement is included in the Department’s FY 2022-2027 Proposed Highway Improvement Program. Current engineering efforts are targeted to enable a contract letting in the middle years of the multi-year program contingent upon plan readiness and funding availability through future annual legislative appropriations.
