Illinois Route 390 Tollway

U.S. Route 20 Interchange Improvement Study

Project Overview

The Illinois Tollway in coordination with the Village of Hanover Park is conducting a Preliminary Engineering Study for improvements of the U.S. Route 20 (Lake Street) Interchange at the Illinois Route 390 Tollway. This study will determine if extending the interchange ramps to County Farm Road, along with local intersection improvements, can address local traffic issues.

The Phase One for the study is expected to require about 18 months to complete with a planned study conclusion scheduled in 2020.

Next Steps

Phase One for the study will be done in coordination with the Village of Hanover Park, DuPage County and the Illinois Department of Transportation. Work in the study area will include:

  • Existing traffic studies and alternative analysis 
  • Environmental field work and studies 
  • Drainage studies 
  • Noise analysis 

Why is the study needed?

The existing interchange at U.S. Route 20 (Lake Street) is the west terminus of the Illinois Route 390 Tollway. The Tollway is coordinating with the Village of Hanover Park to improve the flow of traffic accessing the U.S. Route 20 Interchange to address the local traffic problems.

The Village of Hanover Park would like to remove the through traffic from Greenbrook Boulevard by expanding the interchange to move the traffic directly to County Farm Road. Peak-hour traffic on Greenbrook Boulevard conflicts with the school bus, car and pedestrian traffic to the multiple schools located on the Greenbrook Boulevard.

The study is following the National Environmental Policy Act, which will allow the local communities to seek federal funding for a future project. The Tollway Roadway and Interchange Cost Sharing Policy requires a local share of at least 50 percent for the cost of improvements. The local communities may consider pursuing federal funding to offset the local share of the interchange improvements.

Existing Conditions

It is anticipated that the proposed improvements will be built within the existing right-of-way with possible proposed right-of-way at the intersections.

The Illinois Tollway has jurisdiction for the Illinois Route 390 Tollway and its ramps. IDOT has jurisdiction of U.S. Route 20. DuPage County has jurisdiction of County Farm Road and Greenbrook Boulevard. The land between County Farm Road and U.S. Route 20 is owned by the State.

Environmental impacts are not anticipated for any features other than minimal wetland impacts within the existing right-of-way. 

Public Outreach

An initial stakeholder meeting was held on September 11, 2018, with the Tollway, IDOT, DuPage County, Cook County, Hanover Park, Bartlett, Elgin, and Hanover Township. The Tollway will be holding ongoing stakeholder meetings throughout the project.

A public information meeting for the project took place on August 20, 2019, at Hanover Park Village Hall to present the existing conditions and solicit input on potential solutions. A final public meeting is anticipated in 2020 to present the preferred alternative.
