With construction ramping up along Interstate 15 the Idaho Transportation Department (ITD) is asking motorists to drive defensively and take alternate routes when possible. Work occurring at the south Blackfoot exit (Exit 89) and north of Exit 93 has resulted in increased congestion along the corridor.

“We recommend Blackfoot residents take an alternate route such as U.S. Highway 91 to an exit north of the Rose area,” Engineer Kevin Sonico said. Doing so not only decreases the number of vehicles on I-15, but also allows motorists to avoid driving through the construction zone north of Blackfoot.

The repaving project north of Blackfoot will improve safety and drivers’ experience with a smooth new surface. During construction traffic is shifted to the southbound lanes through a crossover. Drivers should expect reduced speeds through the construction zone. The project is expected to take about seven weeks to complete.

Work at Exit 89 consists of rehabilitating the bridge surface by repairing joints and potholes. This will extend the life of the bridge. “Our goal is to have this done by September 1,” said Engineer Zak Johnson. “We really want to have everything done before the start of the fair.”

Johnson also recommends drivers take US-91 as an alternate route whenever possible.

Motorists are encouraged to stay updated on project detours and traffic impacts at https://511.idaho.gov or on the 511 app.

Work begins to resurface I-15 north of Blackfoot

On Monday the Idaho Transportation Department will begin work to repave the northbound lanes of Interstate 15 from the West Blackfoot Interchange Exit 93 to Riverside Canal near the Rose Road Interchange Exit 98. This project will improve safety and the drivers’ experience with a smooth new surface.

During construction traffic will be shifted to the southbound lanes through a crossover. Drivers should expect reduced speeds through the construction zone. The project is expected to take 50 days to complete.

Throughout the course of the project, crews will be milling down the base layer of the highway to fully reconstruct the road base and driving surface. Work includes pulverizing the existing asphalt, excavating and placing new material as a base, and then paving over the top of the new base.

Travelers are encouraged to use the Idaho 511 system for updated traffic impacts through the construction season.

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

POCATELLO – Beginning tonight and continuing through Wednesday morning, nighttime closures will be in place for a section of Interstate 15 and Interstate 86 at the System Interchange allowing crews to safely place girders for one of the new bridges.

The I-86 eastbound to I-15 northbound ramp will be closed from 8 p.m. to 6 a.m. Monday and Tuesday nights. Drivers looking to head north on I-15 from I-86 will be detoured through the Pocatello Creek 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.

Drivers can also use the 511 app for the latest traffic conditions on all state roadways.

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.

Two projects starting Monday will cause delays on SH-33 in Teton valley

State Highway 33 between mileposts 151 and 152 where a new passing lane will be constructed.

Two projects are set to begin Monday to create a center mumble strip and add a passing lane on State Highway 33. Motorists will experience lane closures and delays at various times through the summer.

A mumble strip along the center line of SH-33 will be added to increase safety and avoid collisions from the intersection of State Highway 32 to the Wyoming state line. The mumble strip will not be added within the city limits of Tetonia, Driggs and Victor. All striping will also be redone. This project will close one lane in the current work area and be complete within two weeks. Mumble strips are similar to rumble strips but are rounded so noise is heard by the driver and less by surrounding homes and businesses.

Work on the addition of a passing lane, center and right turn lanes and the realignment of Baseline Road along SH-33 between Victor and Teton Pass also begins Monday. Drivers should plan for delays between 15 and 30 minutes as temporary signals will alternate traffic through the work zone from mileposts 151 to 153. Crews will remove outdated concrete cattle underpasses and widen the road to ultimately give motorists a chance to pass slow-moving vehicles before entering Teton Pass. This work will be complete mid to late-September.

Motorists should remember to use caution and be patient through construction zones as the Idaho Transportation Department and contractors work to make the road better for the future. Stay up to date on status of these projects and others by visiting 511.idaho.gov, calling 5-1-1 or downloading the app.

Construction continues on I-15 at Inkom

The Idaho Transportation Department is continuing work on the Interstate roadway and bridges from the south Inkom interchange to the Portneuf interchange. Ongoing work includes guardrail repair, paving, and patching and repairing bridge decks. In addition, crews are patching pier caps, applying epoxy overlays, and waterproofing parapets on the Rapid Creek, South Inkom interchange, and Portneuf River bridges.

Work is anticipated to continue through the end of June with single lane crossovers. Drivers are reminded to slow down in work zones, allow other vehicles to merge, and drive defensively.

Replacement of the West Inkom interchange, Union Pacific Railroad, and Main Street bridges are still planned for next year.

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.

Drivers can also check or download the 511 app for the last traffic conditions on all state highways and freeways.

Nighttime detours start for System Interchange

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.

New bridge to open at Chubbuck exit

POCATELLO – Tomorrow afternoon the Idaho Transportation Department will open the new bridge on westbound Interstate 86 near Exit 61 for Chubbuck. Traffic patterns are expected to change between 3 p.m. and 4 p.m.

Once the new bridge is open, westbound traffic will no longer be crossed over to the eastbound lanes. Traffic will flow normally, though westbound travelers will only have one lane.

Crews will continue working in the area for another week to open the other lanes on the bridge. Drivers are urged to follow posted speed limits and share the road.

The bridge over the Union Pacific railroad tracks was replaced to create three lanes for westbound traffic to better integrate with the redesign of the I-86 and I-15 System Interchange.

Travelers are reminded to know before they go and check 511.idaho.gov for traffic impacts.
