Pavement repairs begin across eastern Idaho this summer

Pavement improvements on east Idaho road

RIGBY— The Idaho Transportation Department is utilizing the summer window of opportunity to resurface and repair several roadways across eastern Idaho. Pavement overlays and repairs increase the strength and longevity of our roads, helping them to better withstand the weather conditions in this region. Beginning mid-July, motorists can expect to see traffic limited to one lane as needed in the following work zones:

Interstate 15, milepost 112 at Bingham County line to Exit 119 at U.S. Highway 20 Interchange. Work in this area through Idaho Falls will be conducted at night from 8 p.m. to 6:30 a.m. Traffic will be limited to one lane intermittently in both directions where crews are actively working. Work is expected to last approximately three weeks.

I-15 Exit 119 to Exit 143 at Sage Junction. Traffic will also be limited to one lane intermittently in both directions where crews are actively working. Work on this section of the interstate will be conducted during daytime hours and last until mid-October.

US-20 from milepost 264 at Bonneville County line to milepost 301 at the Idaho National Laboratory junction. Beginning mid-July, patch and repair work will be underway, with flaggers and one-lane closures in the working area. This section of road will also undergo a seal coat later in August. Work is expected to be complete by mid-August.

State Highway 28 milepost 101 at Lemhi River Bridge to milepost 125 at Baker, and milepost 305 to 306 on SH-93 in Salmon. These pavement projects require that a mobile hot mix plant be set up closer to the area of work so asphalt temperatures can be kept where they need to be to correctly build the road. This operation entails equipment parts and pieces being hauled with large transport trucks and then constructed at the Leadore state gravel pit. Once the plant is set up and operational, work is anticipated to last approximately eight weeks. Expect one-lane closures along SH-28 with pilot cars and flaggers in place.

SH-93 milepost 108 at Mackay to milepost 115 at Mackay Reservoir, and milepost 139 at Willow Creek Summit to SH-75 junction. Traffic will be limited to one lane intermittently using pilot cars and flaggers in the current working area. Both lanes will be open again overnight. Work is expected to begin late July and last until mid-September.

US-26 northeast of Craters of the Moon visitor center from milepost 230- 240. This section of road will be dug out and replaced with new pavement. Pilot cars and flaggers will direct traffic through one lane. Work is expected to be complete in just six days, beginning in early August.

Remember to use caution and stay alert when traveling through work zones. Up-to-date information on these projects is available by visiting 511.idaho.gov, dialing 5-1-1, or downloading the 511 app.

US-20 Exit 332 in Rexburg to fully close Wednesday, May 29 for construction

Exit 332 on U.S. Highway 20 in Rexburg will completely close for one month beginning next Wednesday, May 29 to allow crews to quickly build a new unique diverging diamond interchange (DDI) that will greatly improve the flow of traffic.

All ramps at this exit and University Boulevard between the ramps will be closed to traffic and detoured to nearby interchanges. Through traffic on US-20 will be unaffected during construction.

Detours include Exit 328 at Thorton and Main Street Exit 333 in Rexburg. A temporary signal has been set up at Exit 333 to accommodate additional traffic. Access to businesses near Exit 332 will remain open with signage in place to direct drivers.

“Closing the exit allows crews to work at a significantly faster rate. Our goal is to have this interchange reopened before the Fourth of July,” Resident Engineer and Project Manager Conner Huffaker said.

Motorists should use caution and be aware of congestion. Crews will coordinate with emergency responders to ensure access through the closed construction zone when needed.

Once Exit 332 is reopened, work to construct the same DDI design at Exit 333 will begin. The closure of Exit 333 is expected to begin late July or early August.
