US Route 45 (LaGrange Road) Reconstruction and Widening

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.

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.

Note: IDOT projects typically have three distinct phases. Phase I (or the project Study) consists of developing the project scope, environmental studies and preliminary design of a project. Phase II (Design) consists of refining the design to develop contract plans and land acquisition. Phase III (Construction) consists of the actual construction of the project.

The scope of work involves the reconstruction and the inclusion of additional lanes to US Route 45 from 131st Street to 179th Street in Cook County in the Villages of Orland Hills, Orland Park, Palos Park and Tinley Park. The proposed US Route 45 roadway cross section will consist of 3 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. A decorative continuous lighting system will be provided along the section of US Route 45 that is located in the Village of Orland Park. The profile of US Route 45 under the Metra Railroad Bridge will be raised to alleviate recurring flooding problems at the underpass. The Village of Orland Park will be providing enhancements within their corporate limits which include median planter boxes, parkway trees, underground sprinkler system, brick side walk, stamped colored concrete cross walks, and monuments at corner radii.

The Department has worked closely with all the local communities within the project limits. Pedestrian and bicycle accommodations have been incorporated at various locations that match with the community’s needs and future plans. Sidewalk will be installed on the east side of US 45 from 179th to 175th. A multi-use path will be installed on the east side from 175th to 159th. Then, sidewalk will be installed on both sides of the road from 159th to 142nd and on the east side up to Creek Drive. The multi-use path will extend from 142nd to Creek Drive on the west side of US 45

The project also includes 2 omission areas. The intersection of US Route 45 at 159th Street was widened and expanded in 2005 and will be an omission to the corridor. The intersection of 143rd Street was widened and expanded in 2011 and will also be an omission. The estimated construction duration will tentatively extend two construction seasons starting in summer of 2013 with an overall completion of summer of 2015. The total estimated construction cost of the overall projects amounts to $95 million dollars.

Maintenance of Traffic

Typical Exhibitsmall.jpg

This segment of US Route 45 carries high volumes of regional traffic as well as local traffic, some of which use the route as part of a longer commute, while other traffic is traveling to and from local business. For this reason, the Department committed to maintain two through lanes of traffic in each direction for the mainline work; therefore the sequencing of traffic will be as follows:

During the summer of 2013 the two advanced contracts will replace some of the center median with temporary pavement. During this work access across the median may be restricted. Once work begins on the mainline contracts, the remaining temporary pavement will be constructed, the majority of which is along the west side of US Route 45. This temporary pavement will allow traffic to be shifted so that new pavement can be built in stages.

The first stage will construct the entire new northbound pavement, including drainage and work in the sidewalk area. Plans have been prepared which will complete some level of full pedestrian accommodations along the north side where they are planned by the completion of this stage. Vehicles will be shifted to the west side of the road on lanes that provide two through lanes in each direction separated by a center median that will provide room for dedicated left turns at side streets, or for vehicles to access driveways during construction.

Once this stage is completed, traffic will be shifted to the east to drive on the new pavement. During this stage all of the new southbound lanes will be built, again including drainage and work in the sidewalk areas. As in the previous stage, two through lanes of traffic in each direction will be maintained separated by a center lane for left turning vehicles.

The last stage of construction will entail construction of the new pavement for the left turn bays, the landscape items and the center median. Once the barrier median is completed, access to and from some of the driveways within the project corridor will change. Access will be limited to right-in/right-out. Travelers to these locations may need to make a u-turn along US Route 45 to reach their final destination.

There will be occasional overnight or off peak lane restrictions for utility relocation work, placement of temporary pavement or drainage work. When this takes place, one lane of through traffic will be maintained so that vehicles will always have access and use of US Route 45.

The new pavement is going to be concrete, which requires time for the contractor to build properly. At locations of smaller side streets there is not enough room for stage construction of this area. Periodic closure of these cross streets will be required. This has been determined to be the safest way to build the pavement in these areas for both the contractor and the motoring public. No two adjacent cross streets will be closed at the same time. The closure days will be conveyed to the public well in advance of when the work needs to be completed and detour routes will be posted.

Project Municipality:  Orland Hills, Orland Park, Palos Park & Tinley Park
Project County:  Cook

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.
