RTA logo Cook-DuPage Corridor Study

Study Description

The RTA led the Cook-DuPage Corridor study with the Illinois Department of Transportation (IDOT) to examine a broad range of transportation system improvements to address the mobility needs in the western suburbs of Chicago. The Cook-DuPage Corridor covers a large portion of the Chicago metropolitan area and is centrally located in the region. It extends approximately 30 miles from Cicero Avenue (IL50) in the city of Chicago/town of Cicero to the Kane/DuPage county line. Metra's Milwaukee District-West and Burlington Northern Santa-Fe commuter lines form the north and south boundaries respectively. The corridor spans all or portions of 51 municipalities in suburban Cook and DuPage counties and the Austin neighborhood of Chicago, an area that includes over 1 million residents and 750,000 jobs.

The Cook-DuPage Corridor is one of several corridors recommended for multi-modal analysis in the 2030 Regional Transportation Plan (CATS, October 2003). The Plan includes a number of major transit and highway proposals to address congestion and improve mobility in the western suburbs of Cook and DuPage counties. These are: High Occupancy Vehicle (HOV) lanes on the west end of the Eisenhower Expy. (I-290); Additional lanes on the East-West Tollway (I-88); Extension of the CTA Blue Line Congress branch to the western suburbs of DuPage County; Ogden Avenue transitway, from Navy Pier to North Riverside; Cermak Road bus rapid transit; DuPage County "J" bus rapid transit corridor, connecting Naperville, Oak Brook, O'Hare and Schaumburg; Inner Circumferential rail service (IHB/BRC) between O'Hare and Midway.

Mobility problems and potential solutions will be examined in three study phases spanning 2003-2010: 1) Travel Market Analysis, 2) Options Feasiblity, and 3) System Analysis. Locally led study components will be undertaken to formulate corridor planning standards and community development and land use plans/policies.

Program:Community Planning
Program Year:2003
Project Type(s):Transit Improvement Plan
Current Activities:The Cook-DuPage Corridor Travel Market Analysis final report was published in December 2005. The second phase of study, Options Feasibility, was begun in early 2006 and completed in mid 2008. The RTA officially closed the Cook DuPage Corridor Study in April 2009.

All of the major capital projects in the region including Cook-DuPage Corridor proposed projects for system expansion now are being evaluated by the Chicago Metropolitan Agency for Planning for the Go To 2040 Plan. In addition, many of the projects in the recommended system are now moving to a more concrete stage of development through specialized studies undertaken by project sponsors. A Blue Line extension, High Occupancy Vehicle Lane and I-290 Bus Rapid Transit will undergo more detailed cost-effectiveness, ridership, environmental and engineering study through the Illinois Department of Transportation's (IDOT) Preliminary Engineering and Environmental Study (Phase 1). Additional information is available on the project website at Similaly, Bus Rapid Transit is undergoing similar analysis in IDOT's ongoing Elgin-O'Hare West By-Pass Study.
