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.

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

A public hearing concerning the relinquishment of US-26 from Woodruff Avenue to Ammon Road following this improvement project at the intersection of US-26 and Hitt Road was held in January of 2023. Multiple follow-up meetings between ITD, Bonneville County and others were held in the spring of 2023 and 2024. 

Prior to that relinquishment hearing, a public meeting detailing and seeking input on improvements at this intersection was held in September of 2021.
