About the Project


Know before you go


  • WHAT : Replacement of the interchange at Interstates 80/35 and Hickman Road.
  • WHY : Data shows that traffic volume in this area is projected to increase nearly 35 percent by 2042. The updated interchange will improve traffic flow and increase safety.
  • HOW : A diverging diamond configuration, similar to the interchange update in Ankeny at I-35 and 1st Street, will be constructed to increase safety. We’ll also be adding lanes to Hickman Road and adding lanes on I-35/80 from University to Douglas.  Learn more about Diverging Diamond Interchanges.
  • WHEN : All the design work has been completed and the project was awarded to United Contractors in July 2024. Construction began shortly after that. This is a multi-year project that is expected to be finished in 2028.
  • PROJECT BUDGET : $94 million
