Interstate 74 Quad Cities Corridor Study
Draft Environmental Impact Statement and Sec. 4(f) Statement (October, 2003)

The Iowa and Illinois Departments of Transportation, in conjunction with the Federal Highway Administration (FHWA), have initiated planning and preliminary design studies for the improvement of Interstate 74 in Scott County, Iowa and Rock Island County, Illinois. The project begins at the I-74 interchange with 23rd Avenue in Moline, Illinois, and continues north across the Mississippi River to the I-74 interchange with 53rd Street in Davenport, Iowa. The proposed work consists of upgrading the existing 4-lane interstate by providing mainline capacity improvements, interchange modifications, and realigning I-74 across the Mississippi River. This Draft Environmental Impact Statement (DEIS) considers location alternatives for the bridge alignment, alternative interchange configurations, optional lane configurations to increase mainline capacity, and a No-Action alternative. Potential impacts of the alternatives have been evaluated and include those to wetlands, water resources, historic buildings, homes and businesses, and public facilities and services.
