On-ramp to eastbound I-84 at Burley Interchange to close Monday morning

The on-ramp to head east on Interstate 84 at the Burley Interchange will close for the week starting Monday morning for repaving.

The closure will be in place from 6 a.m. Monday (May 19) to 11 p.m. Friday (May 23). To head east on the freeway, drivers will be detoured to the nearest on-ramp about five miles to the east at the Heyburn Interchange (Exit 211).

Drivers will still be able to head west on I-84 from the Burley Interchange. Traffic on I-84 remains two lanes in each direction, and the speed limit is reduced to 65 miles per hour in the work zone.

Construction has been underway since 2024 to update the Burley and Heyburn Interchanges to meet growing traffic demands and is funded as part of Idaho Governor 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.

Area highways to briefly close for railroad replacement and paving work

Railroad crossings along SH-48 in Roberts, Idaho.

REXBURG—The Idaho Transportation Department, in partnership with Union Pacific Railroad, will close highways near several railroad crossings in May.

State Highway 33 from Rexburg to Sage Junction will close Monday through part of Tuesday as needed (May 19-May 20) as Union Pacific Railroad replaces crossings along this route. Motorists can take State Highway 48 to Roberts and Interstate 15 to Sage Junction as an alternative.

SH-48 through the town of Roberts will close through the weekend of May 31-June 3 as three parallel railroad crossings and paving are conducted there as well. I-15 can be accessed at the Osgood Interchange south of Roberts as an alternative.

Digital message boards will be in place along both routes prior to these closures to give motorists advance warning time for making alternative travel plans. Updates regarding these closures will be posted on the Idaho 511 app and at 511.idaho.gov.

Long-term ramp closure and traffic changes begin this month in Caldwell

Extended ramp closures and traffic changes will begin on I-84 this month as the Idaho Transportation Department nears the halfway point of a major interstate reconstruction in Caldwell.

Although exact dates are subject to weather and other factors, ITD expects that:

Tonight (May 15) the 10th Avenue westbound on-ramp will close at 10 p.m. and remain closed through August. Traffic will detour to the westbound on-ramp at Centennial Way. Detour map
On May 22, the Centennial Way westbound off-ramp (Exit 27) will close overnight from 10 p.m. to 5 a.m. so crews can move traffic onto the newly constructed concrete lanes. Traffic will be detoured to the eastbound off-ramp, using the Notus/Parma Exit (Exit 26) to turn around. Detour map
Beginning May 23, westbound traffic exiting at Centennial Way will follow a new ramp configuration, located before the previous off-ramp. Motorists will need to exit early to use the temporary design, which will be in place through August. View map

“Our crews have an enormous amount of work to complete in a tight work zone,” ITD Resident Engineer Styles Salek said. “Closing the 10th Avenue westbound off-ramp this summer allows us to get the work done quickly and safely while the weather holds. We appreciate motorists being patient and planning ahead during construction.”

In addition, motorists can expect occasional nighttime lane restrictions and short-term ramp closures on I-84 this summer. To request email or text updates about upcoming closures, text 84CORRIDOR to 1-866-483-8422 or email 84CORRIDOR@itd.idaho.gov.

The I-84 widening project in Caldwell began in November 2023 and includes:

Widening I-84 to three lanes in each direction with auxiliary lanes between interchanges
Replacing the 10th Avenue Interchange
Removing one westbound on-ramp at the 10th Avenue Interchange
Updating the pedestrian overpass
Building a sound wall along Hannibal Street
Adding a traffic signal at the westbound ramps at the Centennial Way Interchange

The speed limit in the I-84 work zone is 55 mph. With crews, trucks and heavy equipment operating close to traffic, ITD urges motorists to slow down, stay alert and follow all posted signs.

Construction on I-84 in Caldwell will be completed in 2027. For more information, visit itdprojects.idaho.gov/pages/i-84-corridor or call (208) 334-8002.

US-95 paving through Riggins starts next week

Starting Monday, construction will begin on U.S. Highway 95 through the city of Riggins to replace or repair manhole covers and fix soft spots to preserve the highway surface and provide a smoother trip through town.

The work will be from Big Salmon Road north through Riggins.

The public should expect flagging operations with a pilot car on site. Traffic delays should be between 15 and 30 minutes while work is taking place during the day. The speed limit through downtown Riggins is 25 mph, but extra caution is encouraged as there will be heavy equipment and multiple personnel in the work zone.

The project is valued at $1.3 million, and work is anticipated to be completed before the 4^th of July.

Live traffic impacts across the region can be found by visiting 511.idaho.gov. Travelers can also dial 5-1-1 or download the app.

Lane restrictions and closures for sign installation at US-20 Rexburg exits happening this week and next

A drill rig and other equipment, as well as orange traffic control devices, at US-20 Exit 333 while work is being conducted.

REXBURG— One lane and full closures at Exits 332 and 333 off U.S. Highway 20 in Rexburg are ongoing today and into next week. These restrictions are required so contractors can drill deep foundations for the large overhead signs that will soon be the finishing touch on the Diverging Diamond Interchanges completed last fall.

Both of these Rexburg exits will see one lane closures in the areas where drilling work is occurring. Traffic control will move with equipment and the road fully open wherever possible.

Next Monday, May 19 and Tuesday, May 20 Exit 333 will be fully closed overnight from 7 p.m. to 7 a.m. ITD and contractor partners are working through the night so traffic can flow as usual through the daytime hours.

Large equipment, including a drill rig to reach the required 18-foot foundation depth, will need to be in the roadway underneath US-20 for work at both locations, reaching across and over the median concrete barriers. To keep everyone safe and be able to swiftly clean up any water or debris that the drilling creates, lane restrictions and closures have been deemed essential. ITD and contractor partners are committed to completing the work as quickly as possible to cause the least amount of traffic disruption.

“The foundation for the bridge and cantilever posts that will hold the large overhead signs has to be particularly deep,” Resident Engineer Curtis Calderwood stated. “We want them to be secure and have integrity in the wind. This is pretty well the last holdout for getting the exits truly finished.”

These restrictions and closures will be noted on the Idaho 511 app and at 511.idaho.gov.

Drivers should expect busy construction season on SH-55 between Boise and New Meadows

A two-lane highway stretches through a meadow with mountains in the background

Construction season is kicking off on State Highway 55, a vital link in the north-south corridor connecting Boise and Lewiston. With Idaho’s short summer construction window and the need for warm temperatures before snowfall returns, the Idaho Transportation Department will soon begin several key projects along SH-55 to maintain and improve this critical route as shown on the attached map.

Motorists should expect significant delays and are encouraged to travel during off-peak hours—such as early mornings or late evenings. ITD recognizes the inconvenience construction may cause, but each project is part of the department’s continued commitment to enhance safety and mobility along this essential route. From bridge replacements to essential maintenance, these efforts are designed to keep Idahoans moving safely and efficiently throughout the region for many years ahead.

North on the map from Eagle to New Meadows, drivers can expect the following projects this construction season:

Horseshoe Bend to Boise National Forest Boundary Chip Seal (Construction: summer 2025) ITD will apply a chip seal to SH-55 between Horseshoe Bend and the Boise National Forest Boundary to extend the life of the pavement. The highway will be reduced to one lane with pilot cars where crews are working. Work hours are 6 a.m. to 9 p.m. Monday-Thursday, and 6 a.m. to 12 p.m. on Friday from mid-June to mid-August.

Fleming Creek Bridge Replacement (Construction: fall 2024 – late 2025) ITD is replacing the Fleming Creek Bridge on SH-55 approximately four miles south of Banks. The project includes a minor realignment of SH-55 to accommodate the bridge and meet current standards for roadway geometry. Work this year will have minor impacts to motorists.

Banks-Lowman Road Intersection Interim Traffic Signal (Construction: spring 2025) The new signal was activated May 5 and replaces flagging operations that had previously occurred during peak travel periods, providing a safer and more efficient solution for travelers. Travelers may expect delays around the signal.

Rainbow Bridge Maintenance (Construction: spring – fall 2025) ITD will repair concrete bridge elements, replace expansion joints and repair the deck surface. This maintenance is necessary to continue meeting safety and capacity standards until a new bridge is constructed in the future. During the week (Monday-Thursday) one lane of traffic will be open across the bridge. On weekends (Friday-Sunday), both lanes will be open. Prior to Memorial Day, one-lane closures may occur on weekends.

Dynamic Message Sign (Construction: summer 2025) ITD is installing a dynamic message sign on SH-55 this summer between Round Valley and Cascade. The new message board will notify motorists of detours or incidents.

Little Goose Creek Bridge (Construction: June 2024 – fall 2025) ITD is replacing the Little Goose Creek Bridge along SH-55 near New Meadows. This project has been extended due to weather, road conditions and unexpected contractor delays. SH-55 will continue to be reduced to one lane with a traffic signal during construction. Work will be completed this fall.

Motorists are encouraged to check 511.idaho.gov before traveling throughout the state for the latest road conditions and construction updates. However, due to limited cell phone reception along parts of the SH-55 corridor, real-time delays may not always be accurately reflected. Drivers should plan for significant weekend delays and allow extra time for travel.

ITD Island Park foreman addresses multi-fatality crash

ITD Ashton/ Island Park foreman Ryan Wright at the site of a multi-fatality crash on US-20 near the Idaho/ Montana border.

Tragedy is, just that, tragic. The need and desire for reverence is legitimate. Difficult and hallowed situations can also cause strength, character and work ethic to shine admirably.

In sorrow for the lives lost during the crash that this article refers to, and hope that others who can relate will know they are not alone, we share the story of our role in the response.

Idaho State Police and the Idaho Transportation Department in East Idaho have a history that speaks for itself— ISP Lieutenant Marvin Crain and his troopers don’t hesitate to rely on ITD because the partnership has been proven time and time again. ITD operations and maintenance personnel across East Idaho are used to working beside ISP, ready to assist on scene as valuable first responders and traffic control.

Such was the case on the evening of Thursday, May 1, for a multiple fatality crash on US-20 at milepost 399. ITD Ashton/ Island Park foreman Ryan Wright has been in his role for the past 15 years and is an integral part of the small communities he serves. He heard about the incident just after it happened. Knowing it was blocking both north and southbound lanes, he sent his Island Park crew to direct traffic before ISP ever called. Wright then got in his own truck and headed to the scene personally.

“I don’t know what frame of mind a guy goes into it with. I can’t say you get used to it because you don’t,” Wright emphasized. “It’s just something we have to do. I guess it’s just work mode.” He said he tries to keep his crew members from having to be right in the thick of things during crash responses.

Once there, ISP spoke with Wright to request an additional flagger farther south. An Ashton crew member was called and showed up to fill that role. Wright himself pitched in to help however he could, knowing the Fremont County Coroner personally and working alongside the familiar ISP folks involved.

Wright and his crew members were on scene and assisting until the crash was cleared around 2 a.m.

“It’s when you get home and the adrenaline goes down and you start thinking,” Wright said. “The visions in your head you just don’t get rid of.”

East Idaho ITD leadership and Safety Officer Ronnie Butler made contact personally to get CISM, the Critical Incident Stress Management team that exists in each ITD district, available and ready for Wright and his crew. The individuals who are part of a CISM team are trained to offer a listening ear, help manage expectations after a traumatic event, and connect employees to the services needed. Each member is interviewed before joining the team and has related experience of their own.

“I’m not sure why I’ve always been able to handle it because I’ve seen some terrible wrecks,” Wright added. “We each deal with stuff our own way. I’ll usually call another foreman. We have each other.”

In the time since the crash, Wright has had to re-visit the site to assess damage and determine what needs done to ensure the continued integrity of US-20 near the Montana border. This road is the connection to the western entrance of Yellowstone National Park. ITD crews will conduct mastic and grader operations in the coming weeks as soon as investigations allow.

To our ITD operations and maintenance crews across the state, your contributions as first responders and the ones who pitch in during traumatic incidents do not go un-noticed. Thank you for your strength—you are appreciated and of such great worth.

Resources will always be available to help after an incident. Any ITD employee struggling as a result of work or on a personal level, don’t hesitate to contact your CISM representatives—they are happy to help and located to be able to respond immediately. You are not alone.

Installation of new US-95 passing lane near Ferdinand begins

Construction will commence next week to build a new passing lane on U.S. Highway 95 near Ferdinand to smooth traffic flow and provide a safer opportunity to pass.

Drivers should expect to slow to 45 mph during working hours and 55 mph during off hours through the work zone. The contractor will be working primarily Monday – Friday during daylight hours. Motorists may encounter intermittent flagging with alternating traffic that could create 15-minute delays.

The 1.1-mile passing lane will be built on the northbound side of US-95 between Windy Loop Road and Lauer Crossing Road. Starting at the existing edge line, workers will construct the new 12-foot-wide concrete passing lane and widen the existing shoulder by 6 feet. All construction is expected to end in August.

Live traffic impacts across the region can be found by visiting 511.idaho.gov. Travelers can also dial 5-1-1 or download the app.

Westbound I-84 will close Wednesday night between Garrity and Ten Mile exits

Future Interstate 84 and SH-16 Interchange.

The Idaho Transportation Department advises motorists to plan ahead for a full westbound Interstate 84 closure on Wednesday between the Garrity and Ten Mile interchanges. Crews will mobilize a large crane and other materials into the center median of I-84 to begin work on the piers for the new fly-over ramps and work on overhead sign structures. This work will begin the next stage of construction at the future I-84/State Highway 16 System Interchange.

What to expect Wednesday, May 7:

Westbound I-84 will be closed between the Ten Mile (Exit 42) and Garrity (Exit 38) interchanges from 10 p.m. Wednesday to 5 a.m. Thursday. Traffic will exit at Ten Mile (Exit 42) and be detoured down Franklin Road to the Garrity Interchange (Exit 38). Click here for the detour map.

Ongoing nighttime lane restrictions on eastbound and westbound I-84 will take place for several weeks. Work will take place from 7 p.m. to 7 a.m. each night between the Ten Mile and Garrity interchanges (Exits 42 and 38). At least two lanes will remain open overnight. For safety of crews, the speed limit will be reduced to 55 mph at night.
