DUBOIS—Southbound travelers on Interstate 15 are being detoured around the Stoddard Creek Bridge at Exit 184, which has been closed due to a damaged and deteriorating road surface. Interstate traffic is being slowed to 45 mph and directed onto the ramps so drivers can proceed over and through without stopping.
The Idaho Transportation Department has closed W. Camas Creek Road under the bridge to allow for this detour. Operations engineers and facilities managers are monitoring the path to ensure smooth passage for vehicles and semis.
Major improvements to the Stoddard Creek Bridge were already planned for early next spring. With the bridge condition worsening substantially, these have been advanced to start in January. Repairs are expected to take several months, with this closure in place until spring.
The Idaho Transportation Department Dubois maintenance crew and other operations personnel are monitoring the closure daily. Traffic control devices are also weighted and placed to avoid being covered by snow removal efforts. ITD will make necessary changes and efforts to keep traffic in this area moving safely through the winter.
Road updates and status can be found at 511.idaho.gov or on the Idaho 511 app.
Beginning tomorrow at 9 a.m. the Pocatello Creek Road on-ramp to northbound Interstate 15 will be closed to allow crews to remove pavement and to prepare to pave the new on-ramp. The closure is expected to last until approximately 2 p.m. Detours will be in place to guide traffic to the Northgate Interchange or to the Clark Street Exit.
REXBURG—U.S. Highway 20 Exit 332 for University Boulevard in Rexburg will fully close starting Monday, September 30, for crews to complete final paving and striping operations. Work is not expected to take more than a few days, and the exit will be re-opened as soon as it is completed.
This closure was purposefully scheduled during Madison School District’s harvest break to least affect traffic. Detours include Exit 328 (Thornton), Exit 333 (Main Street) and Exit 337 (North Rexburg). After re-opening next week, construction work at Exit 332 will be minimal and off the roadway.
Construction does continue at Exit 333, with one lane running in each direction. These projects to create safe and efficient diverging diamond interchanges at both Rexburg exits are still expected to be complete later this fall.

Beginning tomorrow night, the northbound to westbound ramp of the Interstate 86/Interstate 15 System Interchange will be closed to allow for demolition of the old eastbound to northbound bridge. Traffic intending to travel westbound on Interstate 86 from northbound Interstate 15 will be detoured through the Northgate Interchange. Work will continue until Thursday when the ramp reopens at 7:30 a.m.
Originally built in the 1960s, this is the last existing bridge of the System Interchange that will need demolition as part of the $112 million redesign. The project is scheduled to be completed next summer.
Motorists should carefully follow signs and posted speed limits while traveling through the construction area. With crews working day and night, it is especially important that drivers be alert and proceed safely through the work zone.
Motorists are encouraged to use 511.idaho.gov or the 511 app to keep track of project detours. Project details are also available at https://itdprojects.idaho.gov/pages/i-86i-15-system-interchange
Beginning tomorrow at noon the eastbound Interstate 86 to southbound Interstate 15 ramp will be closed while crews construct a temporary road to the new eastbound to southbound ramp. Eastbound traffic on I-86 looking to travel south on I-15 will be detoured north through the Northgate Interchange (Exit 73). The closed ramp will reopen late Sunday.
This work will allow the eastbound lanes to be adjusted to the grade of the new ramp. Doing the work this weekend will limit traffic impacts during the peak Labor Day weekend.
Originally built in the 1960s, the I-86 and I-15 System Interchange is undergoing $112 million of redesign work to improve safety and replace aging infrastructure. The project is scheduled to be completed next summer.
Motorists should carefully follow signs and posted speed limits while traveling through the construction area. With crews working day and night at the System Interchange it is especially important that drivers be alert and proceed safely through the work area.
Motorists are encouraged to use https://511.idaho.gov or the 511 app to keep track of project detours. Project details are available here on ITD’s projects website —https://itdprojects.idaho.gov/pages/i-86i-15-system-interchange
Beginning tomorrow evening the north-to-west ramp of the System Interchange at Pocatello will be periodically closed to allow for girder placement for a new bridge.
Girders are horizontal steel beams designed to support the bridge deck. As the beams are placed over the northbound to westbound ramp it is necessary to close the roadway beneath for the safety of the travelling public.
Closures are scheduled for:
- Wednesday from 9:00 p.m. until 1:00 a.m.
- Friday from 8:00 p.m. until 6:00 a.m.
- Monday July 22 from 8:00 p.m. until 6:00 a.m.
- Wednesday July 24 from 8:00 p.m. until 6:00 a.m.
- Thursday July 25 from 8:00 p.m. until 6:00 a.m.
Traffic traveling north on I-15 wishing to proceed west on I-86 toward Chubbuck will be detoured through the Northgate Interchange.
Motorists should carefully follow signs and posted speed limits while traveling through the construction area. With crews working day and night at the System Interchange it is especially important that drivers be alert and proceed safely through the work area.
While this work continues, weather is a major factor for the timing of closures. Motorists are encouraged to keep up-to-date via https://511.idaho.gov or the 511 app to keep track of project detours.

Idaho Transportation Department maintenance workers from St. Anthony, Driggs, and Ashton have switched schedules to provide around-the-clock coverage for detours established after the closure of Wyoming State Highway 22 over Teton Pass on June 8.
Drivers are being routed to Idaho State Highway 31 over Pine Creek Pass to Swan Valley, U.S. Highway 26 to Alpine, and US-89 toward Hoback Junction. Crews start the day at 3 a.m. ahead of most commuter traffic. Already these efforts have taken care of roadkill, found and moved an overturned car, and alerted farmers of escaped livestock on the road.
“We’re trying to keep the road and the public safe as best we can with increased traffic,” Operations Foreman Lucas Richins said. “We need people to be on their toes, watching for all the signs, driving patiently and planning extra time to travel due to the congestion.”
Digital message boards are in place at all intersections and areas needed in advance of the detour route. All drivers should be on the lookout for these digital signs that will be updated frequently.
In addition, ITD is staying in coordination with Idaho State Police to help minimize response times to accidents. Drivers should be aware that speed trailers and increased ISP patrols will be in effect.
Guardrail repair and fiber installation efforts along SH-31 have been completed or paused to eliminate any traffic delays.
“We’re doing everything we can to try and make this situation as good as it can be,” said Bryan Young, the acting District Engineer.
Stay up to date on status of the Teton Pass detour routes by visiting 511.idaho.gov, calling 5-1-1 or downloading the app. Travelers can also refer to the Wyoming Department of Transportation Media Kit for daily updates.
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.
More details about these projects can be found at itdprojects.idaho.gov/pages/us20rexburg. Also stay up to date on Idaho road conditions by visiting 511.idaho.gov, calling 5-1-1 or downloading the app.
Beginning Wednesday evening and continuing through Friday morning, nighttime closures will be in place for a section of Interstate 15 and Interstate 86 at the System Interchange to allow crews to safely place girders for one of the new I-86 eastbound to I-15 northbound bridges.
The I-15 northbound to I-86 westbound ramp will be closed from 9 p.m. to 5 a.m. Wednesday and Thursday nights. Drivers looking to head west on I-86 from I-15 will be detoured to the Northgate Interchange.
Ongoing construction at the System Interchange will improve safety and mobility while replacing bridges built in the 1960s. Work is expected to be complete in 2025.
Motorists should exercise caution while travelling through the construction zone. Those wishing to receive email updates about the System Interchange project can sign up at https://lp.constantcontactpages.com/su/g9MMkN9.
