With its centralized location, Siouxland cities have access to excellent air, rail, highway, Interstate, water and pipeline transportation networks. No major U.S. city is more than four hours away from the Siouxland area. Unlike single state locations, the tri-state location provides extraordinary options, choices and ease of accessibility to economical transportation, linking the region to Midwest, U.S. and world destinations.

Current Siouxland Highway Projects

Interstate 29
The goal of the I-29 improvement project is to enhance the safety and operation of Interstate 29 through Sioux City.  The project corridor is divided into three segements.  To find out more about the project including video animation of each segment, click here.


  • US Highway 20
  • US Highway 20, one of the very first coast-to-coast highways in the United States, starts in downtown Boston and travels through Massachusetts, New York, Pennsylvania, Ohio, Indiana, Illinois, Iowa, Nebraska, Wyoming, Idaho, and Oregon.   

    With just 90 miles of the four-lane project left to be completed in Iowa, statewide four-lane US Highway 20 will serve the rapidly expanding alternative energy industry growing in northwest Iowa and provide relief for overcrowded Interstate 80.  For more information regarding the US Highway 20 project, click here.  For an updated  list of US Highway 20 projects funded in the IDOT 5-Year Plan, click here.

    Nebraska Highway 35
    Nebraska Highway 35 Expressway is a 70-mile Planned Project for the Nebraska Expressway System.  This diagonal four-lane segment would connect the confluence of four-lane highways coming from the northeast into Sioux City, Iowa with Norfolk, Nebraska and the four-lane Highway 81 Expressway to Interstate 80.  The Planned 35 Expressway is a significant link that would provide four-lane expressway continuity in the Minnesota, Wisconsin, Illinois, Iowa and Nebraska region and between national destinations.

The following information depicts the miles saved with the new diagonal route:

  • Sioux City to Colorado Springs, CO - 240 miles
  • Sioux City to Grand Island, NE - 96 miles
  • Sioux City to York, NE - 55 miles
