Corridor planning involves transportation, land use, environmental, economic development and population elements over broader areas, usually including multiple public and private agencies. Corridor plans may include transit programs, highway corridor traffic signal coordination, expressway, pedestrian and bicycle programs, etc. Links to corridor plans in DuPage County hosted by other agencies are included below. A list of ongoing corridor projects is included in the left navigation area of this page. Please select the corridor program you would like more information about by clicking on the name of the corridor. If you have any questions about anything you find (or don't find) on the pages here, please contact DuPage County Transportation Planning at (630) 407-6900.
