The Illinois Department of Transportation (IDOT) is interested in learning your thoughts about the existing I-55 corridor, as well as any feedback on other managed lanes you may have used. IDOT is in the early stages of planning for a project which could add a managed lane (carpool lane, toll lane, etc.) to I-55 in an effort to reduce congestion. Please share your travel experiences on I-55 with IDOT by taking the short online survey below.
