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.
