The I-29 project corridor is divided into three segments. These segments are being planned, designed and constructed separately. The data in this layer is designed to give you an interactive view of construction projects that MAY take place between 2015 and 2019 as part of the I-29 improvement project. The goal of the Interstate 29 improvement project is to enhance the safety and operation of Interstate 29 through Sioux City. Last updated: January 2015.
