Illinois has begun a major two-year, $29.6 million project to improve U.S. 45 at I-80
near Orland Park, Tinley Park and Mokena.
The project will rebuild and reconfigure the various ramps at the interchange of U.S. 45 and I-80 and will reconstruct U.S. 45 from north of 179th Street to south of 191st Street. The overall completion date is October 2003.
The first year work from May 20 to October 31 will focus primarily on activities related to ramp construction for the U.S. 45 at I-80 interchange. Most of this work will be done off-road; that is, it will have only occasional direct impact on traffic as all ramps will remain open. However, U.S. 45 will be reduced to one lane in each direction as crews remove the median and install temporary pavement in preparation for next year's work. During 2003, U.S. 45 will be rebuilt as well as the several entrance and exit ramps at I-80.
