The Idaho Transportation Department is closing State Highway 24/U.S. Highway 30 under Interstate 84 at Exit 211 from Friday, April 4, at 6 p.m. through Monday, April 7, at 6 a.m. The closure is necessary to remove the old I-84 bridge as part of the ongoing reconstruction of the Heyburn Interchange.

Detours will be in place to guide motorists through the project area and is expected to add 10 minutes to commutes. Speed limits have been reduced to 65 mph on I-84.

Reconstruction of the Heyburn Interchange is expected to cost $90.1 million and last until late 2026. Since work began in 2024, construction of half of the westbound bridge over US-30, an embankment for the future interchange and center pier for the future interchange structure have been finished.

The next phase of the project includes the removal and construction of the eastbound structure over US-30, removal and construction of the eastbound road and construction of the south half of the interchange.

Built in the early 1960s, the interchange has reached the end of its service life. ITD is focused on improving safety, mobility, and economic opportunity for all users who travel these important agricultural and industrial routes.

Construction is being funded as part of Idaho Governor Brad Little’s Leading Idaho transportation funding initiative. The Leading Idaho initiative allows ITD to take a deliberate approach to advance large projects that will enhance safety, improve mobility, further strengthen Idaho’s economy, and positively impact the Magic Valley and communities across the state for years to come.

ITD demonstrates new Qualified Products List for highway construction items

BOISE – On Tuesday, April 8, ITD will provide training and guidance to suppliers and those seeking to have their materials and products used in highway construction projects added to ITD’s Qualified Products List. The training will be done via a live video which will reside on ITD’s website for several weeks following the live session.

The QPL streamlines the process of testing, evaluating and approving products commonly used on highway construction projects. Rather than evaluating products to determine acceptance for each new project, products proven to meet our specifications are categorized and listed on the QPL.

Although the QPL hasn’t changed, the process of interfacing has been improved and streamlined, so the session on April 8 will demonstrate how it is to be used. The training/demonstration will be held from 11-noon Mountain Time. Project suppliers, distributors, and their agents can access the training through Microsoft Teams by various means listed bat the bottom of this page.

The session will be recorded. If you are unable to attend this demonstration, the recorded presentation can be found at the QPL webpage on our ITD website here:

Nighttime I-84 closures expected through mid-April at the South Jerome Interchange (Exit 168)

The Idaho Transportation Department (ITD) will have intermittent nighttime closures on Interstate 84 under the South Jerome Interchange (Exit 168) through mid-April. The closures will allow crews to form and place bridge abutments, which will provide support for the new Lincoln Avenue bridges. Closures are expected to begin next week, and will take place from 7 p.m. to 6 a.m. Click here to view detour maps.

Starting tonight, eastbound I-84 is expected to close under Lincoln Avenue multiple nights. Eastbound I-84 traffic will use the eastbound ramps to detour around the closure. Eastbound closures are expected to occur at nighttime on:

Wednesday, April 2
Thursday, April 3
Wednesday, April 9

Next week, westbound I-84 is expected to close under Lincoln Avenue multiple nights. Westbound I-84 traffic will use the westbound ramps to detour around the closure. Westbound closures are expected to occur the nights of:

Sunday, April 6
Monday, April 7
Tuesday, April 8

“We encourages motorists to plan ahead for delays and drive with caution when traveling over these next couple of weeks in April,” said Resident Engineer Seth Helms, “We want to thank everyone for their patience as crews work to place the bridge abutments as quickly and safely as possible.”

During the I-84 closures, motorists can expect:

Business access will remain open on local roads and detours will be in place.
Lincoln Avenue may be impacted over I-84 during these closures. Motorists are encouraged to use other routes.
Work is weather-dependent and may be impacted by conditions. Any schedule changes will be announced through email and reflected on Idaho 511

This work is part of ITD’s I-84 South Jerome Interchange (Exit 168) replacement project. Motorists can continue to expect intermittent I-84 and local road closures, traffic shifts and ramp changes throughout the duration of the project. Construction is anticipated to be completed in 2026.

Those who are interested in learning more about the project are invited to visit the project website at itdprojects.idaho.gov/pages/sjeromeic or text 84JTF to 1-866-483-8422.

Drivers should check 511.idaho.gov before traveling to plan for impacts from this project and other work zones.

Look out for crews and traffic control as spring road work begins across East Idaho

ITD crews perform crack sealing repairs on I-15. Men are wearing hi-vis yellow and operating handheld equipment at the back of a small crack sealing trailer.

RIGBY— With the onset of spring, over the next several months the Idaho Transportation Department and contractor partners are crack sealing, repairing potholes, removing hazardous trees and conducting more substantial improvements to ruts and bumps in the roads from Salmon to Driggs and the Montana state lines to Idaho Falls.

Crack sealing is underway on Interstate 15 from Idaho Falls to Dubois, as well as State Highways 33 and 47. This work involves a mobile one-lane restriction that follows workers’ progress. ITD crews fill minor cracks in the roadway with a strong, sticky tar that serves to keep water from getting under the surface and making the damage worse. This must be done in spring during cooler temperatures and dry conditions, and then the repair effectively expands through warmer months.

Flagging operations will be in place temporarily on state highways across east Idaho as ITD performs mastic pothole repair. Expect flagging delays to be less than 15 minutes where this work is occurring. Mastic work uses a hot-applied rubber and asphalt combination that is highly effective at sealing up more substantial damages in the road. These fixes must also be done in dry conditions and specific temperatures seen during the spring. Crews time work before or after peak travel times, even at night as needed.

On U.S. Highway 20 between Rexburg and St. Anthony, crews will be working to mill off the surface of the road in 1,500-foot stretches or less and then overlay new pavement. Expect to see one lane closures and speed reductions where this is occurring.

Hazardous tree removal will also begin this spring on U.S. Highway 93 between Challis and Salmon. ITD crews can sometimes work off the roadway, though flaggers will be in place as needed, with one lane restricted in 15-minute increments. The removal of dying and diseased trees will improve errant driver safety recovery zones, wildlife visibility and fire protection widths. This effort will continue through the spring and into the summer months.

Other routine spring maintenance work like shoulder repairs and delineation enhancements are also ongoing. Drivers should be aware of these smaller work zones, slow down and move over to help everyone stay safe.

Changes to westbound on-ramp at I-90, SH-41 Interchange

Aerial view of the I-90 SH-41 interchange where the future SPUI will be constructed

Next week, as part of the Interstate 90 and State Highway 41 Interchange project, the access point for the westbound I-90 on-ramp is being shifted to the north near Central Avenue. Shifting the on- and off-ramps will provide space for crews to continue working on the new center of the future interchange.

This shift will allow southbound traffic from SH-41 to merge seamlessly onto the on-ramp, rather than requiring drivers to make a dedicated right turn.

Because of this change, starting next week northbound drivers on SH-41 will no longer be able to turn left onto the westbound on-ramp.

Northbound drivers on SH-41 wishing to access westbound I-90 will be detoured north to 16^th Avenue where they will make a U-turn and then return south along the highway until they merge onto the new westbound temporary on-ramp.

Click here for detour map.

This closure will be in effect through fall 2025.

As a reminder, there are several ongoing closures related to the I-90/SH-41 Interchange project that were shared with the community in early March:

The westbound off-ramp remains closed through fall 2025 while crews construct a new straight off-ramp and the single-point urban interchange. Traffic is detoured to the Seltice Way Interchange at Exit 6. Click here for detour map.
Central Avenue will remain closed through late fall while crews continue to widen SH-41. Business access has changed (view map).

This project also includes improvements to SH-41 and surrounding local roads. Construction for this project is expected to be complete in 2026.

City of Post Falls Spokane Street Pavement Rehabilitation Project

As part of ITD’s ongoing efforts to keep the public informed about construction activities and travel impacts, we would also like to share information regarding an upcoming pavement rehabilitation project on Spokane Street that is set to begin on April 7.

This work will reduce traffic to one lane in each direction and will occur in several phases. During some of these phases, there will be intermittent closures of the I-90 on- and off-ramps at Spokane Street.

Full details about the City of Post Falls project are available on the city’s website or by contacting the City of Post Falls Projects Division.

While the ITD and City of Post Falls projects are independent of one another, both agencies are committed to working together to share information with the public. Information about the city’s project and its potential impact on travel routes within the I-90/SH-41 project area will be communicated through email updates, the Idaho 511 system, and ITD’s social media channels as part of our ongoing I-90, SH-41 outreach.

Anyone interested in staying informed is encouraged to register for email updates, utilize the free Idaho 511 system, of follow ITD’s social media channels @idahoitd.

Crack sealing planned for Yellowstone Avenue in Pocatello

The Idaho Transportation Department has begun crack sealing US-91 in Pocatello. Work began Monday on 5th Street and has continued onto 4th Street. Crack sealing north through Pocatello on Yellowstone Avenue will continue as weather permits.

“Once we reach Cedar Street, we will shift to nighttime work to minimize disruption to businesses,” said Pocatello Foreman Anthony Richards. “Other than where the pavement is concrete, we’re planning on continuing north all the way to Walmart.”

The sealant prevents water from entering the pavement causing further erosion and extending the lifespan of the road

Motorists should expect single lane closures in the work zone.

Drivers are encouraged to use the Idaho 511 system for traffic impact updates for this project, and all ITD projects statewide.

I-90 eastbound exit at Cataldo will close for two weeks for paving

On Monday the Interstate 90 eastbound exit at Cataldo near milepost 40 will close for approximately two weeks as crews complete paving work ahead of an upcoming traffic shift in April.

Traffic will detour east to the Kingston exit at milepost 43, and re-enter I-90 westbound to return to the westbound exit at Cataldo.

Traffic through the work zone will continue to be reduced to a single lane at 55 miles per hour for safety.

Once this work is completed all lanes of traffic will be shifted to the westbound side of the interstate so demolition can begin on the eastbound bridge.

Next month daytime river closures will go into effect surrounding the project area. Full details about these impacts and closures are available on the project website.

Drivers are encouraged to use the Idaho 511 system for traffic impact updates for this project, and all ITD projects statewide.

Engineer Paul Franz joins Idaho Transportation Board as new Northern Idaho, D1 representative

Idaho businessman Paul Franz was announced as the newest member of the Idaho Transportation Board Thursday (March 20) at their monthly meeting in Boise. He replaces Jim Thompson, who left the board when his term expired at the end of January after nearly six years.

Franz will represent the five northern Idaho counties. He comes to the board with a background as a professional engineer and former performance manager, in addition to having a strong record of community involvement. In making their announcement a day earlier, Governor Brad Little said, “Paul Franz has the personal and professional qualities to help Idaho advance historic investments in transportation to keep up with the needs of our rapidly growing state.”

“I’m really looking forward to working with Paul on the important transportation issues of a growing state. His engineering and management background will be an invaluable resource as we address these statewide needs,” said Idaho Transportation Board Chairman Bill Moad.

Paul was employed by CPM Development for 42 years until his retirement March 7. CPM is a major Pacific Northwest supplier of concrete, asphalt and aggregates. Franz was President of the Idaho Association of General Contractors in 2007 and has been a board member of the Idaho AGC for the past 22 years.

Franz graduated from the University of Idaho with a Bachelor of Science in Civil Engineering. He and wife, Elizabeth have been married for 41 years and have six adult children.

I-90 paving project begins next week from Wolf Lodge over Fourth of July Pass

Starting next week, the Idaho Transportation Department will begin to resurface an 8-mile stretch of Interstate 90 to preserve and extend the life of the roadway, enhance safety, and deliver a smooth ride for travelers. This will be a two-year project, ending in fall of 2026.

This project will also add illumination near the top of Fourth of July Pass, improve the highway drainage system and replace several miles of concrete barrier.

Work on both eastbound and westbound lanes of traffic will occur simultaneously in small, continuous sections of the 8-mile work zone. There is a scheduled break in construction over winter between the 2025 and 2026 construction seasons, but if mild winter weather prevails, some work may continue to advance the project ahead of schedule.

TRAFFIC IMPACTS

Lane reductions
Speed reductions
Lane width restrictions
Intermittent flagging possible

During construction, drivers can expect traffic to be reduced to a single lane in each direction with reduced speed limits and lane width restrictions. Intermittent flagging may also be necessary at on- and off-ramp locations.

Work will be conducted during daytime hours; however, lane and speed restrictions will remain in effect at all times through the construction season.

This project is one of several that will dot the I-90 corridor from the Washington state line to the Silver Valley in 2025, including the I-90 expansion project between Post Falls and Coeur d’Alene, the I-90 State Highway 41 Interchange project, and the I-90 bridge replacement project near Cataldo.

To assist motorists with safely and effectively navigating the North Idaho interstate system, ITD hosts the Idaho 511 system that is available online, by phone, or by downloading the Idaho 511 app to any smart device. This system allows users to subscribe to notifications along specific routes that will help them stay updated on changing conditions and plan ahead for potential delays. Drivers are strongly encouraged to use this free resource.

ITD team’s quick action “likely saved life” in I-84 car fire

Returning from Idaho Falls via westbound Interstate 84 on a snowy March 6 around noon, ITD’s Travis Hire, Dan Conner from Aero, and Ruth Munoz from Administration spotted a car starting to smoke on the side of the freeway near the Declo Port of Entry, east of Twin Falls. The smoke was threatening to turn to flame.

Hire approached the car, and with heavy smoke billowing by ths time from the engine compartment, he called out. His heart sank as he saw an elderly woman inside the car. The woman was not coherent and “in another minute or two, it likely would have been a fatality,” according to the team. “Timing is everything.”

Dan continued battling the flames with a fire extinguisher focused on the engine compartment, and Ruth called 911 to get emergency services dispatched to the scene.

Acting quickly, Travis opened the passenger door, allowing smoke to escape and revealing the driver still in her seat, disoriented and struggling to speak. Hire saw that flames had already burned through the footwell and knew there was no time to waste. He reassured the driver, unbuckled her seatbelt, and carefully pulled her out through the passenger side to avoid traffic. Once she was safely outside, he checked her for injuries as she took deep breaths of fresh air, working to regain her bearings.

It was a great example of a ‘right place, right time, right team’ confluence.

As the team quickly retrieved the driver’s personal belongings from the vehicle, including items in the trunk.

“To go into a burning car to save someone’s life is ‘next level’ stuff,” Dan said. “I know Travis is uncomfortable with the attention, but I feel he should be recognized. He likely saved her life.”

“Besides, how often does the Emergency Manager who oversees highway rescues actually spearhead the action?!”

Once the woman had been rescued and was out of harm’s way, Simone Webb, Nicole Herrin and Robbie Swajkoski of Financial Services, who’d followed in another ITD vehicle, sat with her in a recovery vehicle until law enforcement arrived to take her statement.

“This was a great team effort, showcasing how we take care of the public,” Travis said. “At the end of the day, she was safe, and that’s what matters most.”

The event in Idaho Falls was the annual State facilities management meeting, where topics ranged from project status checks, to finance, technology, GIS, business managers, Operations engineering lessons learned, duties, roles & responsibilities and more.
