Idaho enters the 100 deadliest days

BOISE — As Memorial Day approaches, Idaho enters the “100 Deadliest Days,” the period between Memorial Day and Labor Day when the state historically experiences a spike in fatal and serious injury crashes. This year, the Idaho Office of Highway Safety (OHS) urges all drivers to prioritize safety and make responsible choices behind the wheel.

According to OHS, as of May 12, 2025, there have been 74 traffic fatalities in Idaho, compared to 57 at the same time last year. This alarming increase underscores the importance of heightened awareness and caution during the summer months.

“We call this period the 100 Deadliest Days, but it would be great to be proven wrong,” said OHS Program Manager Josephine Middleton. “Make it safer out there for yourself and others, and remember, when traveling in rural areas, to be extra vigilant because emergency crash response times are more challenging.”

While winter driving conditions are often perceived as more hazardous, summer presents its own set of challenges. With more people on vacation, attending events, and engaging in recreational activities, the roads become busier. This increase in traffic, combined with factors such as distracted driving, speeding, and impaired driving, contributes to the higher incidence of crashes during this period.

Additionally, warmer weather brings more motorcyclists and bicyclists onto the roads, increasing the need for drivers to remain vigilant and share the road responsibly.

Safety Tips for the 100 Deadliest Days

To help reduce the number of crashes and fatalities, OHS recommends the following:

Wear a Seat Belt: Seat belts increase your odds of surviving a crash by nearly 50%.
Drive Engaged: Stay free from distractions and focus on the road ahead.
Never Drive Impaired: Always plan for a sober ride home, whether it’s a cab, rideshare, designated driver, or staying overnight where you are drinking.
Slow Down: Aggressive driving was involved in 61% of the fatal crashes in rural areas in 2023.

“We have a lot of wonderful partners from law enforcement to construction workers, helping to make Idaho’s roads safe, but we all need to do our part,” Middleton said. “As drivers, we can all do a better job of looking out for each other on our roads and make it safely through this summer.”

Expect delays on US-95 for Thorn Creek Bridge work next week

Construction equipment and work zone at Thorn Creek Bridge along US-95.

Daytime intermittent closures on U.S. Highway 95 between Moscow and Lewiston near Thorn Creek/ Uniontown Cutoff will be in effect next Wednesday and Thursday, May 28 and 29, from 6 a.m. to 6 p.m. while the Idaho Transportation Department is installing new bridge girders at the Thorn Creek Bridge.

The bridge will fully close to both north and southbound traffic while each girder is installed. Girders are the large horizontal beams that will support the new bridge deck being constructed this summer.

Flaggers will be present to allow traffic to pass one direction at a time between each girder installation. Motorists are encouraged to seek an alternative route to avoid delays.

This work at Thorn Creek Bridge is part of a large-scale project improving safety along US-95 from Lewiston to Moscow. Portions of this project are funded as part of Idaho Governor Brad Little’s Leading Idaho transportation funding initiative. These funds are used to make investments in critical state infrastructure to enhance safety, mobility and to sustain Idaho’s strong economy into the future.

Digital message boards are currently in place to alert drivers of these closures next week. Updates can also be found on the Idaho 511 app and at https://511.idaho.gov/.

I-15 Stoddard Creek Exit now open to southbound traffic ahead of Memorial Day

I-15 southbound lanes at Stoddard Creek Exit 184 in east Idaho.

Southbound traffic is now able to travel over the Stoddard Creek Bridge at Interstate 15 Exit 184 just in time for the Memorial Day weekend. Travelers can now turn both right and left onto Stoddard Creek Road underneath the bridge. This road provides access to multiple camping and recreational opportunities in the area.

Southbound 1-15 traffic is no longer diverted onto the Exit 184 ramps, but back onto one lane over the Stoddard Creek Bridge along the main roadway. This one lane closure allows the Idaho Transportation Department and contractor partners to accomplish finishing work, like replacing guardrails, on the passing lane of I-15. Work is expected to be complete and all traffic restrictions removed within the next month.

This update can be seen on the Idaho 511 app and at https://511.idaho.gov/.

Summer closure of Ustick Road will begin next week between Owyhee Storm Avenue and McDermott Bypass

The Idaho Transportation Department will begin major work next week on the future State Highway 16 and Ustick Road Interchange. Starting Tuesday, May 27, Ustick Road will be closed from Owyhee Storm Avenue to McDermott Bypass until late August.

Motorists can expect that:

Ustick Road will be closed between Owyhee Storm Avenue and McDermott Bypass.
Traffic will be detoured around the work zone. Click here for the detour map.
Access to homes within the closure will be maintained.
Temporary traffic signals will be in place at the Cherry/McDermott and Ustick/Can-Ada intersections as requested by ACHD and the city of Nampa.

The closure will give crews room to widen Ustick Road immediately around the interchange and connect the on- and off- ramps for the interchange.

“Our goal is to complete as much work as possible while schools are out of session,” Project Manager Dan Gorley said. “We look forward to the completion of this interchange, and we thank the community for their patience during construction.”

The Ustick Road Interchange is anticipated to be completed in 2027. Intermittent lane closures will continue in the area over the next year.

Resurfacing to begin Tuesday on US-95 in Cambridge

The Idaho Transportation Department will begin a road resurfacing project on five miles of U.S. Highway 95 in and around the city of Cambridge on May 27. The project is designed to extend the life of the roadway, improve ride quality, and enhance safety for drivers and pedestrians.

Motorists should expect delays in the area as crews will close one lane at a time during daytime hours, Monday through Friday, with no work scheduled on weekends or holidays. Flaggers and pilot cars will guide traffic safely through the work zone.

This project includes:

Resurfacing the roadway with a mill and inlay to extend the life of the pavement and improve ride quality for drivers.
Slope repairs to address soil instability south of the Cambridge city limits. This work will begin immediately and require a lane closure controlled by a temporary traffic signal. This closure will be in place less than two weeks.
Sidewalk pedestrian ramp replacements to improve accessibility and safety for pedestrians.

The speed limit will be reduced through the work zone for the safety of workers and travelers. This project is expected to be complete by mid-July.

ITD encourages drivers to plan ahead and use caution in construction areas. For the latest updates on road conditions and detours, visit 511.

Lane Closures Begin Next Week Near I-84/I-86 Interchange for Chip Sealing

Starting next week, drivers should expect lane closures on Interstate 84 between Malta/Yale (Exit 228) and Idahome (Exit 237) as crews perform chip sealing to preserve and extend the life of the roadway. A short section of Interstate 86 near the interchange will also be included in the project.

Traffic will be reduced to a single lane in both directions during the two-week operation. On- and off-ramps within the work zone will also be chip sealed. While no ramps will be fully closed, half of each ramp will be closed at a time to allow traffic to continue flowing.

Speed limits will be reduced to 55 mph on the mainline and 35 mph on ramps during construction. Drivers are urged to allow extra time and avoid following other vehicles too closely to prevent windshield damage.

For updates, visit 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.
