Welcome to the US Route 45 Reconstruction & Widening Website!

Based on increased traffic demands that have caused safety and operational concerns, the Illinois Department of Transportation will be improving US Route 45 (LaGrange Road) from 131st Street to 179th Street in Cook County. The project traverses the Villages of Orland Hills, Orland Park, Palos Park & Tinley Park.

The scope of work involves the reconstruction and the inclusion of additional lanes to US Route 45 to accommodate the design year 2030 traffic. The Metra bridge which crosses US Route 45 has been reconstructed. The proposed US Route 45 roadway cross section will consist of three through lanes in each direction with a continuous landscaped barrier median and curb and gutter on each side of US Route 45. The outside through lanes will be 12 feet wide and the 2 inside lanes will be built 11 feet wide. The landscaped barrier median will be 28 feet wide.

Project Start: Summer, 2013
Project End: Fall, 2015
Project Cost: $95,000,000
Project Municipality: Orland Hills, Orland Park, Palos Park & Tinley Park
Project County: Cook

This site has been created to provide one location where the public can get details about the US Route 45 project scope and the construction staging and schedule. The information is intended to help you understand what we will be doing and when the work is anticipated to take place.

As the Department works to make this section of roadway safer for the future, we want to make sure users, residents and local business owners have up to date information on the progress of the project. If you have any questions about the project that have not been answered with the information on this site, please use the “Contact Us” section and a response will be sent to you.


UPDATE  - Spring 2014

Work being performed by utility companies to relocate utility facilities is taking longer than originally estimated and the severe weather this past winter have impacted the progress of the roadway work. Work is currently expected to be complete by late Fall 2015.

Did you know work zone fatalities are down 29.6 percent compared to 2003? Aggressive law enforcement and awareness campaigns and significant improvements to work zone safety traffic control reduced Illinois work zone fatalities from 44 in 2003, including 5 workers, to provisionally 30 with 3 workers killed in 2010.
So, Give ‘em a brake…slow down for their sake and yours!
