IDOT to pursue P3 for I-55 managed lanes project

Illinois– The Illinois Department of Transportation (IDOT) will update the public today on proposed changes to its Interstate 55 managed lanes project. Originally intended to add a single lane in each direction between Interstate 294 and Interstate 90/94, IDOT now hopes to include a second managed lane.


The state received federal approval in 2016 to build a single managed lane in each direction of I-55 between Interstate 355 near Bolingbrook to I-90/94, the Dan Ryan Expressway, in Chicago. IDOT would pursue a public-private partnership to fund the project, though a funding source hasn’t been identified. The managed lanes would be tolled.The project website is here.
