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 Crews will remove outdated concrete cattle underpasses and widen the road to ultimately give motorists a chance to pass slow-moving vehicles before entering Teton Pass.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.

Construction work at the intersection of U.S. Highway 26 (Yellowstone) and Anderson/Lincoln Road in Idaho Falls begins this weekend and will continue June 8-9. Anderson/Lincoln will be closed to through traffic and no left turns will be allowed off Yellowstone. Roads will re-open and traffic resume as normal on Sunday night both weekends.The intersection was also a work zone last year and was unable to be successfully completed with the onset of winter weather.
The City of Idaho Falls requested that the Idaho Transportation Department arrange to have work done over weekend time frames to affect the fewest commuting drivers. ITD is working with the contractor to ensure the most minimal impact while fully completing improvements at the intersection. It is the project goal to complete one half of the work this weekend on June 1-2, and the other half over June 8-9 to ensure the least amount of closure and detours possible. Any changes to that schedule will be communicated if necessary.
Motorists will see the current road surface being milled up and removed to put stronger asphalt in place. Stone matrix asphalt (SMA), a newer construction alternative than the concrete previously used at this intersection, will be laid in solid segments to avoid weak joints and give the new section of road as much as a 20-year life cycle.
Remember to use caution and be patient through construction zones as the Idaho Transportation Department and our contractor partners work to make the road better for the future. Stay up to date on status of this project and others by visiting 511.idaho.gov, calling 5-1-1 or downloading the app.
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.

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.
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 online.

The historic rebuild of the System Interchange in Pocatello is nearing the halfway point, and motorists will continue to see progress in the coming year.
Major milestones for the upcoming season include building five new bridges and demolishing one bridge. Bridges will be constructed to carry southbound traffic on Interstate 15, traffic over Chubbuck Road and traffic heading east on Interstate 86 to access northbound I-15.
As crews come back from the holidays, next up for the project will be drilling concrete shafts for the foundations of the new southbound bridges on I-15. Each shaft will be 8 feet in diameter and drilled up to 60 feet deep to support the weight of I-15 passing overhead. Motorists will also notice construction of retaining walls for the new ramp from I-86 eastbound to I-15 northbound.
This winter crews will be in multiple locations throughout the worksite. Motorists are reminded to follow posted speed limits and watch for work vehicles entering and leaving the interstate at any time day or night.
Originally built in the 1960s, the interchange is undergoing a $112 million redesign to improve safety and replace aging infrastructure. These safety improvements include:
- Redesigning ramps to have drivers trying to head northbound on I-15 from I-86 merge from the right, rather than the left.
- Traffic from Pocatello Creek Road will no longer have to cross three lanes to head to Chubbuck. Instead drivers will travel under the northbound and southbound lanes of I-15.
- Chubbuck Road will be transformed from an overpass into underpass. This means oversized vehicles will no longer have to detour off the interstate. Those who walk and bike will also be better able to travel from Chubbuck to the Portneuf Wellness Complex on the east side of the interstate.
Construction is slated for completion in 2025. Those wishing to learn more about the project can visit the website at itdprojects.idaho.gov/pages/i-86i-15-system-interchange.
The northbound off-ramp at the Fort Hall Interchange (Exit 80) is scheduled to close Monday at noon as crews finish paving the new off-ramp. Work is expected to be completed by 5 p.m.
The closure will last approximately four hours and is dependent on favorable weather conditions. During the closure traffic will be detoured to Exit 89.
The Fort Hall Interchange is undergoing a complete reconstruction to replace the outdated bridge and improve on- and off-ramps. The redesign also allows for the planned three lanes northbound and southbound on I-15. Those wishing to learn more about the project can visit https://itdprojects.idaho.gov/pages/i-15-fort-hall-interchange.
Beginning Monday and continuing through Wednesday, nighttime closures will be in place for a section of Interstate 15 and Interstate 86 at the System Interchange to allow crews to safely remove overhead signage.
One southbound lane will be closed on I-15, and the southbound ramp to I-86 will also be closed. Drivers looking to head west on I-86 will be detoured off the interstate at Northgate, west to State Highway 91, and then south to the Chubbuck Interchange. The closures will last from 9:30 p.m. until 5:30 a.m. each night.
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.
