I-90/94 Dan Ryan Expressway

Running south near Chicago's US Cellular Field (Comiskey Park) is a 9-mile, 40-year old segment of the Dan Ryan Expressway (I-90/94) on which the Illinois Department of Transportation is completing over $400 million in reconstruction. The section of roadway carries 300,000 cars per day. The reconstruction project will reduce congestion, improve pavement condition and traffic safety and reduce severe flooding on one of the most heavily traversed urban highway segments in the world.  CTE is responsible for providing comprehensive program management for the entire 9-mile length of the project and designing 3.1 miles of the new highway.

Program management includes monitoring and reporting on schedules and project costs; coordinating all lighting design and construction packaging for the project; design review; and maintenance of the project website to exchange information and resolve design issues.  CTE is preparing contract plans for 3.1 miles of the expressway from 47th Street to 69th Street. The scope of the project includes reconstruction of the existing northbound and southbound express lanes (four in each direction) and local lanes (two in each direction) of the I-90/94 pavement, the addition of auxiliary lanes in each direction of the local lanes, and modifications to all ramps. The work will also involve bridge construction and reconfiguration of the Chicago Skyway/Dan Ryan interchange to provide an additional entrance ramp from the Skyway to the northbound Dan Ryan express lanes. The work will include the construction of new retaining walls and the rehabilitation, and/or modifications of several existing retaining walls and any roadway and traffic signal improvements required at cross streets and alternate routes. In addition, the rehabilitation will provide a new highway lighting system, new highway drainage collector systems, new expressway signing, and other incidental work as required to complete the reconstruction of this segment of the expressway.
