US-26 & Hitt Road (25th East) Intersection

Improvements are in the works for the busy intersection of US-26 and Hitt Road in Idaho Falls. The road will be expanded up to five lanes as early as late 2026- 2027.

Update Winter 2026

Design for this project has undergone multiple revisions to accommodate area business owners and ensure effective, safe mobility at this intersection. Each change results in time needed for further approval. We also know that the components of a new traffic signal take a particularly long amount of time to receive. These factors could result in construction beginning in 2027, though construction may possibly be a reality in late 2026.

Overview

Design work on the Hitt Road intersection in Idaho Falls is under final review and motorists can expect to see construction that will improve safety and mobility as early as this fall of 2026.

Idaho Falls

ITD has analyzed needed improvements to the intersection of US-26 (Yellowstone Highway) and 25th East (Hitt Road) in 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

Community Input

Iona Road

Public meetings were held in September 2021, April 2022 and January 2023 regarding this project and the potential relinquishment of surrounding sections of US-26 through the future. Three alternatives were originally shared for the US-26 and Hitt Road intersection, with the final design now underway having been chosen with the help of positive public feedback. ITD has been working with Bonneville County, area business owners and other partners as this project has progressed since those meetings.
