    • Temporary Lane and Road Closures

Why is the LaGrange Road Project being completed?
For more than two decades, IDOT and the municipalities of Orland Park, Orland Hills, Tinley Park, and Palos Park have listened public to input and conducted studies of roadway conditions (e.g., traffic volumes, accidents, etc.) to form the LaGrange Road Corridor Improvement Project.

Currently, LaGrange Road carries 40,000 vehicles per day and is projected to carry upwards to 65,000 vehicles per day in the year 2040. These improvements are necessary to improve traffic flow and safety through this essential transportation corridor.

What are the construction limits of the LaGrange Road Project?
The construction limits include LaGrange Road from 179th Street to north of Creek Drive. The improvements extend east and west at key intersections.

Who is performing the roadway expansion?
The LaGrange Road Corridor Project is being led by IDOT. Although primarily a state-led project, the municipalities along the corridor have been involved with this project since its inception. IDOT and the corridor communities continue to be proactive to keep motorists, businesses, residents and others informed.

What is the project time frame and staging of the project?
Starting May 6, 2013, advance work will be starting and is anticipated to be complete by July 26, 2013. This work includes median removal, median storm sewer installation, tree removal, and drainage improvements in the area south of 153rd Street. Portions of this work will be performed between the hours of 7 p.m. and 6 a.m. and will include intermittent lane closures. IDOT’s contractor, D Construction of Coal City, will be performing this work.

On April 26, 2013, IDOT opened bids for the main line contract work. Award of this work is anticipated within six to eight weeks, and construction will start shortly after. Temporary widening will be constructed on the west side of LaGrange Road. Traffic will then be shifted to the west side of LaGrange Road with construction of the east half taking place.

Once the east half of LaGrange Road is constructed, northbound traffic will utilize the new pavement to allow the middle section of LaGrange Road to be built. Upon completion of the middle section, south-bound traffic will be shifted east to allow for the construction of the remaining portions of the west side of LaGrange Road.

This work is scheduled to be complete in the spring of 2015. This schedule and construction staging is dependent on weather and utility relocations and are subject to change. Updates will be provided as the project progresses.

Will there be any posted detours allowing motorists to avoid the construction?
While there will be lane closures, LaGrange Road is not scheduled to be fully closed during the construction process. The intent of the project is to maintain two lanes of traffic throughout the corridor. Construction will cause shifts in traffic patterns and intermittent lane closures which will cause traffic delays. Those traveling the corridor are advised to stay informed on elements of the project and plan ahead. Detours will be posted during the construction of the corridor for the closure of the following roads:
  • 175th Street
  • 171st Street
  • 153rd Street
  • 149th Street
  • 147th Street
  • 144th Place

Consecutive streets will not be closed at the same time during construction.

Will access to businesses be affected?
Access to businesses will be maintained throughout construction. There will be times that access will need to be closed to reconstruct the business entrance. However, there will always be access to each business. IDOT will be posting driveway entrance signs throughout the corridor to help identify driveway locations along LaGrange Road. During this time the village will remain flexible and allow temporary signage for individual businesses.

Will there be roadway enhancements as part of the project?
The Village of Orland Park will be enhancing the corridor with both landscape and hardscape improvements. The improvements include brick paver enhancements along the medians and sidewalks; enhanced cross walks, median walls, and columns; additional monument and fencing at key intersections; median and parkway trees; and irrigation, decorative street lighting, and median plantings.

Pedestrian enhancements include both sidewalks and multi-use paths throughout the corridor. Intersection crossings will have pedestrian signals with count down timers.
