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.

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

WORK ZONE SAFETY
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!
