Upcoming Traffic Changes
- All ramps have been opened and will remain open for the project in 2026. The contractor is working primarily in the middle of the interstate and the current traffic configuration (as of June 1, 2026) will remain in place throughout the fall of this year (most likely sometime in September).
About the Project
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
