IDOT and FHWA began the Elgin O’Hare – West Bypass (EOWB) project in 2007 to study transportation issues in a 127-square mile project area west of O’Hare Airport. IDOT has completed the preliminary engineering and environmental studies (Phase I) for the project. The project is now advancing to design (Phase II) and implementation (Phase III) as an Illinois Tollway project.
