Public Meeting Held In December 2017

The Illinois Department of Transportation (IDOT) held an open house public meeting to review important updates to the preliminary engineering and environmental study (Phase I) for the improvement of Interstate 55 from Interstate 355 to Interstate 90/94 project.

Environmental approval was received by the Federal Highway Administration in July 2016 for one managed lane, which will operate as an Express Toll Lane (ETL) in each direction. IDOT has initiated a new Phase I study to further improve operations and reliability along the corridor by evaluating the addition of a second ETL within the median from east of Interstate 294  to I-90/94 while the section from I-355 to I-294 would remain as one ETL in each direction.

Corridor Planning Group Meeting #1

The first Corridor Planning Group Meeting (CPG) for the I-55 Managed Lane Project was on Thursday, October 5, 2017 at the Stadium Club in Toyota Park, 7000 Harlem Avenue, Bridgeview, IL 60455.

I-55 Managed Lane Project Receives Environmental Approval

The Federal Highway Administration (FHWA) has determined that the Illinois Department of Transportation’s proposed I-55 Managed Lane Project will have no significant impact on the human environment. The FHWA issued a Finding of No Significant Impact (FONSI) based on the Environmental Assessment (EA) prepared for the study. A FONSI is a brief document that concludes the process and documents the decision as to why an action will not have a significant impact on the environment.

The EA studied the addition of managed lanes in each direction in the existing I-55 median between I-355 and I-90/94. The proposed managed lanes would improve mobility and operational efficiency by offering a reliable travel time option in the increasingly congested corridor.

The EA was conducted in accordance with the National Environmental Policy Act (NEPA) that requires that environmental impacts be fully considered for any project using federal funding. The NEPA process requires federal agencies to integrate environmental values into their decision-making process by considering the environmental impacts of their proposed actions and reasonable alternatives to these actions.
IDOT assessed the natural, built, and human environment to determine the extent of impacts that may arise from constructing and operating the project. Environmental factors such as air quality, wildlife, vegetation, water quality, wetlands, geology, neighborhoods, park/recreation areas, utilities, visual quality, and cultural resources were assessed.

The FONSI represents FHWA’s acceptance and approval of the I-55 Managed Lane Project. The complete FONSI letter may be viewed here. The EA document may be viewed here.
