POCATELLO – Beginning Thursday morning work crews at the System Interchange will begin pile driving piers for new bridges. As part of Governor Little’s Leading Idaho initiative, the project was fast-tracked partly due to the aging 1960s bridges due for replacement. The new piers will create a stable foundation to protect the structure of the new bridges.
Pile driving uses a hydraulic hammer that forces piers downward through the soil. Unavoidably, the operation creates noise as the hammer falls on the pier. Work for this portion of the project will be conducted during the daytime. However, in the next week or two additional pile driving will be required at Chubbuck Road that will include some nighttime work.
Motorists should carefully follow signs and posted speed limits while travelling through the construction area. With crews working day and night and with the onset of winter it is especially important that drivers be alert and proceed safely through the work area. Drivers are encouraged to check https://511.idaho.gov or the 511 app to keep track of road conditions and construction. Project details are available on ITD’s projects website — https://itdprojects.org/projects/i-86-i-15-system-interchange/
This project is partially funded with Transportation Expansion and Congestion Mitigation (TECM) funds as part of Governor Little’s Leading Idaho initiative. 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.
Pile driving utilizes a hydraulic hammer to place the piles deep below the surface of the ground.
POCATELLO – The Idaho Transportation Department’s rebuild of the System Interchange for I-86 and I-15 at Pocatello is in full swing with crews working multiple areas throughout the worksite. As part of Governor Little’s Leading Idaho initiative, the project is quickly changing how the heart of the Interstate in Pocatello appears.
The lowering of the ramp for westbound traffic from northbound I-15 to I-86 is now complete and work on building the new bridges is beginning. Temporary barriers are in place at multiple locations and motorists will also notice changes in lane striping as traffic is shifted away from work areas.
Cranes are being placed to begin drilling shafts for bridge piers.
One safety innovation being implemented is the use of a conveyor belt system to move earth fill from one area of the project to another. The conveyor allows crews to move material without using trucks entering and exiting the Interstate. That makes for a safer work zone for drivers and work crews. It is important that public keep clear of the conveyor system for their own safety.
In the coming weeks cranes will appear on the project and begin drilling shafts for new bridge piers. Excavators and other earthmoving equipment are also working in multiple areas to reprofile the land. Throughout the work zone water trucks are being utilized to keep dust down. Inspectors and engineers are also on-site daily ensuring safety and compliance with designs.
Near the end of the month or early next month pile driving will begin in the northern portion of the work area. There will be some associated noise during this portion of the operation.
Speed limits in the work area are now set at 55mph and should always be carefully observed, day and night. Crews are working long hours including some night work. Drivers should also know that lane configurations are changing and should be prepared to adjust to the difference by watching for signs and following pavement markings.
It is especially important with such a large project that motorists plan for extra time and to be patient with other drivers by allowing them to merge and change lanes as needed. Sharing the road and watching for workers and construction vehicles entering the Interstate is essential to keeping everyone safe.
The historic rebuild of the I-86/I-15 System Interchange was the outgrowth of a need to replace aging bridges and improve safety. The bridges, built in the 1960s, are currently safe but needed to be replaced due to their age. Failure to do so would result in a need to place restrictive load limits which would hinder commerce.
Water trucks are working tirelessly to keep dust from construction to a minimum.
ITD also noted an increase in aggressive lane changes and congestion within the interchange, particularly just north of the Pocatello Creek exit. The rapid motion of entering I-15 at Pocatello Creek and crossing to the passing lane to exit toward Chubbuck did not exist when the interchange was built. However, with population growth and associated development that traffic is now significant. Such “exit left” and “enter left” movements do not meet driver expectations, cause confusion, and results in frustration for drivers.
Another much-needed improvement was a redesign of the Chubbuck Road crossing. The old 1962 bridge is narrow and has limited capacity for pedestrians and bicyclists. With the growth of Pocatello and the addition of the Portneuf Wellness Complex a significant change was needed. ITD’s new design changes Chubbuck Road from being an overpass over I-15 to an underpass beneath the freeway with dedicated bike lanes and wider sidewalks. Removal of the bridge also creates more space for the larger project to handle increased traffic.
Once completed, the new System Interchange will be safer and ready to carry the increased traffic volumes for the fastest growing state in America.

POCATELLO – Beginning this evening at approximately 8:00 p.m. paint crews will be restriping the ramp from I-86 to I-15 southbound. Work will continue through the night and will end at approximately 6:00 am tomorrow. During the restriping work the ramp will be closed and southbound traffic will be detoured through the Northgate Interchange. While it is hoped the work will be completed in one night, there is a possibility the detour will also be used Thursday night to finish striping.
Motorists should carefully follow road signs, obey work zone speed limits, and share the road with other vehicles navigating detours.
POCATELLO – The northwest ramp from I-15 to I-86 reopened this morning at the System Interchange in Pocatello. Traffic heading from I-15 toward Chubbuck and American Falls is no longer detoured through the Northgate Interchange. The detour was needed to lower the ramp so new bridges can be built for I-15 through the System Interchange.

POCATELLO – Beginning tonight, Tuesday September 6 at 10:00 p.m., the northwest ramp of the System Interchange at Pocatello will be closed for construction. The closure will allow the ramp to be lowered prior to beginning bridge construction.
Motorists travelling north on I-15 wishing to proceed west on I-86 toward Chubbuck will be detoured through the Northgate Interchange. The closure and detour will remain for approximately three weeks until the new ramp is completed.

POCATELLO – Multiple fires are burning along I-15 at Pocatello. There is also a fire at Malad Summit on I-15. Fire crews are actively working in the areas, but traffic is delayed or blocked. Motorists are encouraged to slow down, watch for and move over for emergency vehicles and check 511.idaho.gov or the ITD 511 app to receive road status updates. The causes of the fires are not yet known.
Drivers should take extra care while driving through Idaho this weekend with fire danger high amid unseasonably warm temperatures. In particular, motorists should:
Ensure tow chains on trailers are not dragging which can cause sparks.
Tires on vehicles and trailers are in good condition for highway driving. A blown tire can cause the wheel rim to kick sparks into dry grass.
Never throw cigarettes or other combustible materials out of a vehicle.
Never throw glass or other litter out of a vehicle. Glass bottles and other objects can reflect or focus the sun’s rays causing ignition.
Do not park your vehicle over dry grasses when you pull off a road. The exhaust and other hot portions of the undercarriage can ignite a fire.
Fire crews responding to one of the fires along I-15A burned area near the southbound lane of I-15Pocatello Fire Department and other agencies quickly responded to the fires.
AMERICAN FALLS – The Idaho Transportation Department began repairs on two I-86 bridges in Power County this week. The Sunbeam Road and Seagull Bay bridges will both be receiving new roadway surfaces to protect the integrity of the bridges and improve safety. The first phase of the project will progress for one month while the eastbound bridges are resurfaced. The second phase will also last one month as the westbound bridges are similarly repaired. All work is scheduled to be completed by the end of October.
During construction traffic will be moved to one side of the Interstate prior to the bridges and some exiting traffic will be detoured. After the construction area is passed, traffic will cross back over to the regular side of the Interstate to proceed as usual. Motorists should watch closely for signs indicating lane changes, detours, and speed limit reductions.
During the current first phase, eastbound traffic is being crossed over to the westbound side of the Interstate prior to Sunbeam Road at American Falls. Traffic remains two-way on the westbound side of the Interstate until past Seagull Bay Exit 44. Therefore, eastbound Interstate traffic will not be able to use Exit 40 into American Falls and Exit 44 to Seagull Bay. Motorists should instead exit at the west American Falls / Rockland Exit 36 or the Rainbow Road Exit 49.
American Falls residents will still be able to enter I-86 toward Pocatello at the Exit 40 on ramp. They will progress eastbound until the Seagull Bay Exit 44 where they will detour through the exit and then re-enter the Interstate and merge with through traffic as it crosses back over from the westbound lanes.
Performing work on both bridges at the same time reduces costs and effects repairs in the same construction season. Once completed the new surfaces will be smoother and the bridge decks will be protected against further deterioration.
The change will return US-91 (State Street) to a 4-lane road through the city of Preston.
PRESTON – On August 25th the Idaho Transportation Department will begin a $433,000 chip seal coating operation on State Street in Preston. At the request of the city, ITD will also restripe the road to return it to a four-lane configuration. Work will continue until September 9th with a brief pause during the Labor Day weekend.
From the beginning of the project until the 29th there will be no parking on State Street. In addition, there may be up to 15 minute delays for motorists.
Chip sealing, also called seal coating, maximizes the taxpayers’ investment by extending the lifespan of the pavement. A sticky slurry is sprayed on the pavement, rock chips are applied on top of the slurry for a long-lasting seal. Hot, daytime temperatures are needed to ensure a successful application. Chip sealing protects pavement from sun, oxidation, weather, water, oil and gas, and improves friction for drivers.
CHUBBUCK – On Wednesday August 10th the Chubbuck Road overpass will be closed over I-15 to facilitate demolition of the overpass. As part of the “Leading Idaho” program’s I-86/I-15 System Interchange rebuild, the Chubbuck Road crossing will be converted from an overpass to an underpass.
Due to the amount of traffic on I-15, construction of the new underpass will occur in stages while the rest of the project progresses. As such, the new underpass is scheduled to be completed in the fall of 2024.
This project is partially funded with Transportation Expansion and Congestion Mitigation (TECM) funds as part of Governor Little’s Leading Idaho initiative. 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.
The Chubbuck Road detour will take motorists through the Northgate Interchange.
The new design changes Chubbuck Road into an underpass with additional space for pedestrians and bicycle lanes.
Idaho Governor Brad Little’s “Leading Idaho” funding initiative paved the way recently for badly needed runway improvements at the Malad City Airport.
Leading Idaho funding supplied 100% of project costs, to the tune of $1.6M.
The project began in September 2021 and finished in late July. It was managed by local airport officials and Idaho’s Division of Aeronautics. The airfield at Malad City is one of 48 community airports statewide that are managed by Aero, which is part of the Idaho Transportation Department.
Malad’s City Airport was at the top of the list for funding due to a runway that only scored a 37 (of 100) in the most recent Pavement Condition Index (PCI) – a rating that translated to “Very Poor.” The PCI is the primary rating tool to determine the level of pavement distress and subsequent need for improvement.
The Malad City Airport is just the first of many small community airports across the state that will utilize these Leading Idaho funds to tackle needed repairs.
“A huge thank you to Governor Little for his Leading Idaho Grant and for the State of Idaho Aeronautics for trusting in Oneida County – Malad Airport with the grant funds to rebuild our runway,” said Malad City Airport Office Manager Roxanne Albretsen. “We are beyond grateful and will maintain and keep it in beautiful condition for years to come!”
Airport Board member Mike Hess, in comments made to the local newspaper, TheIdaho Enterprise, said the biggest beneficiaries of the runway improvement would include “Life Flight first and foremost; saving lives as Malad relies on medical transport in many life-threatening cases.”
Without a well-maintained runway, critical patients must be taken by ambulance to the nearest trauma center, which can often make a significant difference in their medical intervention.
Hess continued, “Firefighting would be next. Almost every year the Forest Service will set up a fire-fighting base there.”
This year’s fire season has not been as extreme as last year’s, but the recent Lemhi County and Yosemite fires suggest the season may have quite a few surprises left, especially as high temperatures and winds are in the forecast for much of August.
Hess also mentioned some less-visible benefits. “Each year, Agricultural spray planes base their operations at the airport for the local agricultural community. There were over 2,200 landings here last year. Many of these will take the Courtesy Car into town and buy lottery tickets and a meal. Many people fly in for other business purposes and/or family visits. Many visitors are flying cross-country and stop to purchase gas, which benefits the county.
The Idaho Department of Commerce has indicated that having a community with rail service, freeway access and an airport are three of the most important considerations new businesses look for when selecting a site.”
As part of Governor Little’s“Leading Idaho” initiative, the 2021 Idaho Legislature dedicated $126 million of one-time funds from Idaho’s budget surplus to transportation projects statewide. The funds were split 60/40 between ITD and local jurisdictions. Construction on this project is paid for with ITD’s portion of the funds that will accelerate projects to replace bridges, restore pavements, and improve mobility in communities across Idaho.
