3 road construction projects begin next week. Where they are and what crews will be doing
Published at | Updated at
IDAHO FALLS – The Idaho Transportation Department is kicking off three different construction projects in eastern Idaho beginning Monday.
The first is happening in Rigby at exit 320. Traffic leaving U.S. Highway 20 to access South Rigby will be detoured while the exit is closed for bridge repairs.
The closure will be in effect from 8 a.m. to 5 p.m. and last only the one day.
Travelers can take exit 322 (North Rigby) or exit 318 (County Line) as detours. Those leaving Rigby to get on to US-20 will still be able to use the southbound ramp at exit 320 toward Idaho Falls as normal.
That same day in American Falls, a $3.5 million project to improve the intersection of Pocatello Avenue and State Highway 39 will get underway.
To improve safety, crews will place a signal at the intersection of Pocatello Avenue and SH-39. SH-39 will also be widened to four lanes from the intersection to Fairgrounds Road. New turn lanes will also be built on SH-39 for traffic heading to Pocatello Avenue.
Construction will take place through August. All lanes will remain open, but traffic will be slowed in the construction zone. Flaggers will be present during different phases of the project. Access to the American Falls Airport and the Power County Fairgrounds will remain open throughout construction.
ITD will return to install the traffic signal in the spring of 2026.
Project details are available on ITD’s projects website
Beginning Tuesday, Main Street in Inkom will be closed for two nights, due to bridge demolition. This is the first part of the Inkom Corridor Project that includes demolition and reconstruction of three bridges.
The Main Street closure will take place from 9 p.m. to 6 a.m. on Tuesday, June 10, and Wednesday, June 11, weather permitting. Bridge demolition will produce a considerable amount of noise.
Traffic will be detoured to Old Highway 91, and flaggers will direct single-lane traffic through the work zone. The detour will only accommodate vehicles with a height of less than 13 feet.
Drivers should expect delays. Watch for crews and drive with extra caution.
