Interstate 74 Iowa-Illinois Corridor

The I-74 corridor provides a vital link between Iowa and Illinois, and an important gateway to the Quad Cities region. Growing population and employment during the past several decades has led to increasing traffic volumes. The current configuration of roadways and bridges along I-74 does not provide consistent travel times along this major transportation corridor. Traffic incidents and maintenance activities on the narrow Mississippi River bridges impede traffic flow. Therefore, improvements to the I-74 corridor are needed to enhance the movement of persons and goods between Iowa and Illinois, and serve the transportation needs for continued economic development in the Quad Cities region.

That's why the Iowa and Illinois Departments of Transportation joined forces with other agencies and local officials to complete the I-74 Iowa-Illinois Corridor Study. This project has examined a wide range of alternatives designed to improve traffic flow and mobility in the project area, which extends from Avenue of the Cities in Moline, Ill., to 53rd Street in Davenport, Iowa.

This project evaluated transportation problems and recommended solutions to improve traffic flow, respect the environment, and complement community goals and plans. A solution for the I-74 corridor was achieved by working collectively and communicating with all concerned parties. The Iowa and Illinois departments of Transportation are working closely with a committee composed of transportation and community officials. Communication with all interested parties was maintained through a series of public hearings to present the findings in the draft environmental impact statement (DEIS), Final environmental impact statement (FEIS), public information meetings, small group meetings, and a speakers bureau. In addition, up-to-date project information will continue to be available in regular newsletters and on the I-74 Iowa-Illinois Corridor website.
