POCATELLO – Aug. 28, 2023 | Southbound drivers on I-15 will be detoured through the interchange ramps at Fort Hall (Exit 80) tonight from 9:30 p.m. to 5 a.m. This will allow crews to operate safely as they work on the bridge beams over the roadway.
The Fort Hall Interchange is undergoing a complete reconstruction to replace the outdated bridge and improve on- and off-ramps.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.org/projects/forthall/
Motorists should exercise caution while travelling through the work zone as traffic patterns will continue to change over the next week to accommodate construction. Drivers can also check 511.idaho.gov or download the 511 app for the last traffic conditions on all state highways and freeways.
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.
Motorists should exercise additional caution while travelling through the construction zone.

POCATELLO – To facilitate construction of the new bridge at Fort Hall Exit 80 on I-15, night closures of the northbound lanes will occur tonight (Aug. 15), Wednesday Aug. 16, Monday Aug. 21 and Wednesday Aug. 23. During tonight’s construction forms will be placed from 9:30 p.m. to 5:00 a.m. The other three nights girders will be erected from 9:30 p.m. to 7:00 a.m. Northbound traffic will be diverted over the old overpass.
Motorists should plan for delays and exercise additional caution while travelling through the construction zone. Check 511.idaho.gov or download the 511 app to your phone for the last traffic conditions.
POCATELLO – Beginning Monday August 7, the Idaho Transportation Department will be resurfacing Interstate 15 from the Rose Interchange 7 miles north to North Lava Rocks. Crossovers will be used to move traffic to the other side of the interstate while work is being done. Motorists should expect reduced speeds during construction. Construction will pause each Friday morning to accommodate weekend traffic.
Work will continue until September 1 when it will be paused for a week to accommodate increased traffic during the Eastern Idaho State Fair. Afterward the project will resume for four additional weeks.
Motorists should check https://511.idaho.gov or download the 511 app for the latest information on road construction.
POCATELLO – The Idaho Transportation Department (ITD) is hosting an open house on June 29 to share information and gather public input about improvements being developed for Interstate 15 (I-15) between the Northgate Interchange (Exit 73) and the Fort Hall Interchange (Exit 80).
“The interstate is in need of improvement as traffic volumes continue to increase in southeast Idaho,” said ITD District 5 Engineering Manager, Eric Staats. “ITD has determined that additional lanes are needed to enhance safety and to meet continued growth and travel demands.”
The I-15 Northgate to Fort Hall Project is part of a multi-year planning process to improve I-15 between Pocatello and Idaho Falls.
“This project between the Northgate Interchange and the Fort Hall Interchange is the first step toward widening I-15 between Pocatello and Idaho Falls,” said Staats. “We would like to get the public’s input on the designs that have been developed for the Northgate to Fort Hall segment.”
The public is invited to stop by the open house anytime between 4:00 – 6:30 p.m. on Thursday, June 29, at the Shoshone-Bannock Convention Center, Chief Targhee Room (777 Bannock Road) in Fort Hall. Project staff will be available to discuss the project and proposed design plans.
The same information will also be available online between June 29 – July 14. Participants are invited to review materials and submit comments online. For more information, please visit the project website at https://itdprojects.org/projects/i15northgatetoblackfoot/
Elements of this project are being funded with Transportation Expansion and Congestion Mitigation (TECM) funds as part of the Leading Idaho Program. The program allows ITD to accelerate project timelines to address rapid growth and build critical infrastructure today that would otherwise take many years to fund and build.
BLACKFOOT – Beginning Monday the Idaho Transportation Department will begin work on pavement preservation projects in the Blackfoot area on Interstate 15 and US Highway 91. Motorists should plan for single lane closures and reduced speed limits in the work zones.
Interstate 15 will receive a micro-surfacing treatment north of the Blackfoot rest area. Micro-surfacing improves and protects the road surface.
On US-91 from Shelley to York Road, ITD will begin chip sealing. Chip sealing, also called seal coating, maximizes the taxpayers’ investment by extending the lifespan of the pavement. Hot temperatures are needed to ensure a successful application. Chip sealing protects pavement from sun, oxidation, weather, water, oil and gas, and improves traction for drivers.
As work progresses, the I-15 Business Loop through Blackfoot will also be improved. All work is scheduled to be completed by mid-July.
Please check 511.idaho.gov or the 511 app for the most recent information on road work.
POCATELLO – As temperatures warm motorists will see nighttime work starting up again at the System Interchange project in Pocatello. In addition, there will be short-term detours while girders are placed for the new northbound bridge. As of this morning the east to northbound ramp is closed. Traffic is being diverted south to detour through the Pocatello Creek interchange.
Heavy equipment will be moving earth during the night as contractors rebuild the interchange. The excavated earth will be moved on the large conveyor system the Idaho Transportation Department has been using to limit the need for heavy trucks entering and exiting the Interstate within the work zone.
The massive project requires nearly round-the-clock work during summer months to achieve the goals set by ITD for project completion. During the nighttime work nearby businesses and residents may notice more noise from the heavy equipment moving about the worksite.
Detours necessitated by the placement of girders will be updated on 511.idaho.gov or in the 511 app. While this work continues, weather is major factor for the timing of closures. Motorists are encouraged to keep up-to-date via 511.
Motorists should exercise additional care at night to keep everyone safe. ITD asks motorists to keep their eyes on the road, slow down, obey signs, and be patient with other drivers.
The System Interchange project is part of Governor Little’s “Leading Idaho” initiative that pays for shovel-ready projects to move forward without delay.
POCATELLO – The recent snowstorm has delayed delivery of girders for the new I-15 bridge at the System Interchange in Pocatello. ITD planned to install the girders this weekend, but they could not be safely delivered to Pocatello in time. This means the planned lane closures for this weekend will also be delayed until all of the girders can be safely delivered to Pocatello. When that occurs, ITD will update the public.
To protect Idaho’s workers and other motorists, ITD asks those travelling on Idaho’s highways to follow work zone speed limits, be patient, and plan for extra time to travel to their destinations.

POCATELLO – With the arrival of spring the Idaho Transportation Department is ramping-up construction at the System Interchange in Pocatello. As part of Governor Little’s “Leading Idaho” initiative, the System Interchange is being redesigned to replace aging bridges built in the 1960s and improve traffic safety.
While work at the interchange continued throughout the winter, in the coming week ITD’s contractor will be placing girders for the new I-15 northbound bridge. This will necessitate rolling slowdowns, delays, and short detours around the I-86 to I-15 ramp leading from Chubbuck toward Blackfoot.
Additionally, as work progresses into the first week of April the Chubbuck Road bridge will be demolished. This will be done in stages with traffic detoured through Chubbuck at night. The first closure will be for northbound traffic and the second for southbound I-15 traffic.
Other projects will also see ramped-up operations including the Fort Hall Interchange and bridge work on I-86. With unprecedented funding made available for construction, Idaho motorists will continue to see increased activity on Idaho’s highways.
To protect Idaho’s workers and other motorists, ITD asks those travelling on Idaho’s highways to follow work zone speed limits, be patient, and plan for extra time to travel to their destinations.
