I-55 Managed Lane Project

The Illinois Department of Transportation (IDOT) is currently engaged in a preliminary engineering and environmental (Phase I) study for the improvement of I-55 from I-355 (Veterans Memorial Tollway) to I-90/94 (Dan Ryan Expressway) in DuPage and Cook Counties.  The Phase I Study began in the spring of 2012 and is following the Federal National Environmental Policy Act (NEPA) process, which facilitate an open and transparent study.  It also will follow the Illinois Department of Transportation (IDOT) Context Sensitive Solutions (CSS) policy, which provides for numerous public involvement opportunities.

This project will study an addition of one managed lane in each direction (generally within the existing median of I-55). The study area begins at I-355 and continues east to I-90/94.
