Update November 2026
This project was delayed when plans had to undergo multiple revisions to accommodate area business owners and ensure effective, safe mobility. Each change resulted in time needed for further environmental approval. With all factors complete, this project bid is open now and a contractor will be selected within the month. Construction is expected to begin in April and last into the fall of 2027. Click here to see the contractor presentation and even more details of what this project entails.
ITD has analyzed needed improvements to the intersection of US-26 (Yellowstone Highway) and 25th East (Hitt Road) in Idaho Falls, Bonneville County. In addition to this intersection, analysis was also done on the intersections of Hitt Road and E. Iona Road, and US-26 (Yellowstone Highway) and E. Iona Road, as well as potential impacts to traffic at other nearby intersections.

Safety
This project will improve the safety and capacity of the intersection by:
- Replacing the traffic signals
- Widening Hitt Road from two lanes to up to five lanes, with an additional two lanes at the intersection
- Replacing the roundabout with a traffic signal at the intersection of Iona Road and Hitt Road
- Creating three lanes on Iona Road
- Adding sidewalks and lighting to improve pedestrian safety while traversing this area
Upcoming Traffic Impacts
As construction occurs through the spring and summer of 2027, motorists will be affected by as many as seven different traffic shifts through the work zone. All impacts will be signed, with flaggers and traffic control present as needed. Project plans do provide for traffic to continue in both directions to the greatest degree possible and business access to be maintained. Drivers are encouraged to seek surrounding alternate routes to avoid delays. Information will be shared regularly during construction via ITD’s social media channels and online community groups. Thank you to drivers for understanding that the frustration will be worth it and greatly improve the area for the long term future!

Advancing Safety: Iona Road
Altering the intersection of US-26 and Iona Road to allow right-turn only movement was always a part of the Hitt Road intersection project. Following multiple severe crashes on US-26 through 2026, and in cooperation with Bonneville County, the decision was made to advance this change immediately. Temporary median barriers were placed in August and outreach conducted to re-route vehicles and encourage the use of traffic signals at both Hitt Road and Woodruff Avenue. These barriers and signage will become more permanent as part of construction in 2027.
