ITD making changes to ensure detour routes for the Teton Pass stay open

Cars traveling along Idaho State Highway 31, part of the detour route while Wyoming Highway 22 over Teton Pass is closed.

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.

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

US-20 Rexburg Exits Closures

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.

Nighttime detour planned for I-15/I-86 System Interchange this week

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.

Beginning Saturday evening drivers should expect various nighttime detours through next week at the System Interchange in Pocatello as crew demolish old bridges on southbound Interstate 15.

Two detours are scheduled for two nights each.

Eastbound travelers on Interstate 86 trying to head north on Interstate 15 will be detoured to the Pocatello Creek Interchange the following nights:

  • Saturday, Dec. 16, from 9 p.m. to 7:30 a.m.
  • Sunday, Dec. 17, from 7:30 p.m. to 7:30 a.m.

Northbound travelers on I-15 trying to head westbound on I-86 will be detoured to the Northgate Interchange  the following nights:

  • Tuesday, Dec. 19, from 7:30 p.m. to 7:30 a.m.
  • Wednesday, Dec. 20, from 7:30 p.m. to 7:30 a.m.

During these detours it is important that drivers follow posted speed limits. As work will continue through the winter drivers need to be particularly cautious around snowplows by giving them extra room in the work zone.

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. Those wishing to learn more about the project can visit the website: https://itdprojects.idaho.gov/pages/i-86i-15-system-interchange.

Detour planned for Monday at Fort Hall (Exit 80)

I-15/I-86 System Interchange daytime detour to continue Wednesday morning

POCATELLO – Due to recent inclement weather, the daytime closure of the north-to-west ramp at the System Interchange will continue into Wednesday. The additional time is needed to complete placement of the steel girders for new bridges.

Traffic will be directed to the Northgate Interchange, adding approximately five minutes to travel times. Drivers will exit at Northgate, cross over I-15, and then proceed south on I-15. The detour will be in place starting at 5 a.m. until work is be completed. The same detour has been in place for the last 3 weekdays.

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.

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.

I-84/US-93 Interchange Ramp Construction

UPDATE: Daytime and nighttime ramp closure on the I-84 Westbound ramp Aug. 29 – Sept. 11. Daytime ramp closure affords construction crews the ability to expedite ramp paving. Project remains on schedule to be completed mid-October.

TWIN FALLS – The Idaho Transportation Department (ITD) begins construction on the I-84 and US-93 interchange on and off-ramps at Exit 173 in August 2023 which is expected to last approximately two months. Located just north of Twin Falls, the project will resurface the ramps, upgrade signals, and construct a right turn lane for the westbound I-84 off-ramp.

The public can expect the following traffic impacts:

  • Lane reductions in place at the on and off-ramps south of I-84.
  • Temporary closures will occur at the on and off-ramps 8 p.m. – 5 a.m.
  • Motorists will drive on a gravel surface during the day on the westbound on and off-ramps.
  • Construction will be staggered and no more than one ramp will be closed at a time.
  • Each ramp closure is expected to last for approximately eight nights.
  • Motorists will need to use alternate routes when closures are in place.
  • Signs and possibly flaggers or a temporary signal will be in place to direct traffic.
