The Illinois Department of Transportation (IDOT) is studying potential highway improvements to Interstate 90 (I-90) between the junction of the Jane Addams Tollway (I-90) and Interstate 190 (I-190) on the west and Illinois Route 43 (Harlem Avenue) on the east -- a distance of approximately 2 miles. The study is being led by IDOT in close coordination with the Federal Highway Administration (FHWA). As the joint lead agencies, IDOT and FHWA will ultimately be the decision-makers for the I-90 project.

The I-90 corridor is located in Cook County and is adjacent to four communities: Chicago, Harwood Heights, Norridge, and Park Ridge. There are two interchanges within this section of I-90, Illinois Route 171 (Cumberland Avenue) and Canfield Avenue, and two multi-modal transit hubs located at Cumberland Avenue and Harlem Avenue.

The purpose of the I-90 Improvements Study is to improve safety and traffic operations, as well as provide an appropriate transition between the Jane Addams Memorial Tollway (I-90), I-190, and the Kennedy Expressway (I-90).

This section of I-90 experiences major congestion due to the merging and diverging of two major highways (I-90 and I-190) and the presence of a busy interchange at Cumberland Avenue. At the eastern end of the project, Harlem Avenue is a major traffic generator which contributes to congested conditions.

In addition, the Illinois Tollway is adding capacity to the Jane Addams Memorial TollwayI-90 northwest of the study area. This could lead to an increase in traffic volumes both on the Tollway and in the project corridor.

The National Environmental Policy Act (NEPA) of 1969 requires the consideration of environmental issues for "major" federal actions. These actions can include use of federal funds, federal land, or federal permits. NEPA is a procedural law that requires any planning data or decisions incorporated in planning documents to meet NEPA and the Council on Environmental Quality standards.

CSS and Community Input

Illinois Department of Transportation has identified this study as a Context Sensitive Solutions (CSS) project. This approach enhances public outreach and participation in the transportation planning process and provides more opportunity for community input into the transportation solution for the I-90 study. Since community issues can be complex, the CSS process works as a partnership between IDOT and stakeholders to come up with working solutions to Illinois’ transportation needs.

Context Sensitive Solutions (CSS) Approach

The I-90 Phase I Study will utilize Context Sensitive Solutions (CSS), ...'a collaborative, interdisciplinary approach that involves all stakeholders to develop a transportation facility that fits its physical setting and preserves scenic, aesthetic, historic and environmental resources, while maintaining safety and mobility.' - Federal Highway Administration.
