Draft FY 2025-2029 Iowa Transportation Improvement Program presented to the Iowa Transportation Commission today

AMES, Iowa – May 14, 2024 – The Iowa Department of Transportation presented the Iowa Transportation Commission with the draft Fiscal Year 2025-2029 Iowa Transportation Improvement Program at its meeting today. The draft Program documents investments in Iowa’s multimodal transportation system covering aviation, public transit, railroads, trails, and highways.

The Program is developed and approved annually by the Commission and includes specific highway and bridge projects anticipated to be constructed over the next five years on the state highway system made up of all Interstate, U.S., and Iowa signed routes. All other roads in the state are under the jurisdiction of individual cities and counties and each local jurisdiction develops their own program of highway, road, street, and bridge construction projects.

Program overview

The highway and bridge projects included in this draft Program are funded with approximately $4.5 billion of state and federal funding forecast to be available over the next five years. Projects included in the Program are consistent with the goals and objectives of the State Long-Range Transportation Plan and identified following a detailed evaluation of safety, traffic, congestion, condition, and other data. This assures the projects are those necessary to provide modern, safe, and efficient transportation of goods and the traveling public.

The Commission prioritizes investments that improve the safety and condition of existing state highways and bridges, and this draft Program includes approximately $3.9 billion of investments in that area. Significant investments in bridges have been made over the last 18 years dropping the number of poor condition bridges on the state highway system from 256 in 2006 to 23 in 2024. This draft Program includes nearly $1.5 billion of additional bridge investments.

The interstate system connects all transportation systems in Iowa and facilitates the efficient movement of freight within, to/from, and through Iowa. This draft Program invests in projects that add capacity where necessary, replace major river crossings, and modernize interchanges to improve safety and to handle future traffic demands such as:

  • I-80 Middle Road interchange reconstruction in Bettendorf
  • I-35/80/235 Southwest Mixmaster modernization in Polk County
  • I-380 improvement from Swan Lake Road to 120th Street in Linn County
  • I-380 improvement from 120th Street to U.S. 30 (including Wright Brothers interchange reconstruction) in Linn County
  • Bridge replacement and widening of I-35 at the U.S. 30 interchange
  • Addition of over 50 truck parking spots.


Projects in this Program that address safety and operational needs include:

  • Resiliency work on Iowa 21 near Belle Plaine
  • U.S. 75 north of Sioux Center to south junction with U.S. 18 to replace aging pavement
  • Iowa 149 Des Moines River bridge to Woodland Avenue in Ottumwa to replace aging pavement
  • Iowa 12 Gordon Drive bridge in Sioux City to replace an aging viaduct
  • Iowa 58 Greenhill Road interchange in Waterloo to replace an existing at-grade intersection
  • U.S. 151 interchange with County Road X-20 at Springville to replace an existing at-grade intersection
  • U.S. 30 interchange at 610th Avenue at Nevada to replace an existing at-grade intersection
  • Super-2 improvements on U.S. 63 in Tama County to provide more passing opportunities
  • Super 2 improvements on U.S. 18 in Kossuth County which address operational needs

The draft Program is posted and available for public comment on the Iowa DOT's website The Commission is currently scheduled to consider approval of the Program at its meeting to be held on June 11.
