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 over 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.
