The goal of the Interstate 29 improvement project is to enhance the safety and operation of I-29 through Sioux City. The decision to improve the corridor is based on the need to improve safety, improve traffic operations, provide for driver expectancy, and improve roadway infrastructure conditions.
The I-29 project corridor is divided into three segments. Segment 2 (downtown) construction is ongoing with mainline completion anticipated in 2019.
