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.

 

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.

 

 

With tree removal and utility relocation mostly complete, construction is set to begin on the stretch of highway from State Highway 41 to Greystone Road near Athol.

Starting next week the right of way along the south side of SH-54 – including the unofficial off-road trails – will be closed to all traffic due to the active work zone with heavy equipment. This closure is necessary to ensure the safety of everyone, including those using the trails, construction crews, and others on the adjacent roadway.

 

Why is the right of way area closing?
The first phase of highway expansion, which will occur from early spring through mid summer, will focus primarily on the south side of the highway. Significant demolition and construction will take place in the right of way area adjacent to the roadway, including excavation, ditching, and paving. This work will involve heavy equipment and work crews, making the area unpredictable and, more importantly, unsafe for any kind of traffic – both motorized and non-motorized. This includes motorcycles, ATV’s, side by sides, bikes, pedestrians, and equestrian riders.

We understand that these closures may cause frustration, especially for those who have come to rely on the trail as a secondary route of travel. The main concern, however, is safety.

Who will be affected?

All trail users will be affected by this closure, but with the proximity of both Timberlake High School and Middle School, it’s important for parents to understand this route will also not be accessible for students, teens or underage drivers who use the trail to get themselves back and forth to the schools or to their extracurricular activities.

 

What does this mean for off-road vehicle traffic?
Since the unpaved right of way area along SH-54 will be closed during construction, it will not be acceptable for any un-registered off-road vehicles or unlicensed drivers to use the state highway as an alternative route. Highway traffic is governed by strict regulations, and the presence of off-road vehicles or unlicensed drivers would pose serious safety risks to both those operating ORVs and other road users. Off-road vehicles cannot legally operate on public highways unless appropriately registered and licensed for street use.

To ensure everyone’s safety, all ORV users will need to plan alternative routes or transportation, and we ask that young, unlicensed drivers in particular, avoid using the highway as a shortcut.

We are committed to working together with the community to help navigate through this closure as safely as possible.

This project is essential for improving safety and infrastructure for everyone, including the students and families who use the highway every day.  We appreciate your patience as the project moves forward and we will continue to provide updates on any other developments that may affect the community.

 

Will there be room for a new trail in the right of way after the project is complete?

No. Once the highway expansion project is completed in 2026, the entire width of the right of way will be dedicated to shoulder space and sloping to meet modern roadway engineering standards. This space is necessary to improve traffic flow and ensure the highway complies with current standards and practices that prioritize the safety of users. As a result, there will not be room for an off-road vehicle trail or shared use path in the right of way.

The expanded roadway is designed to accommodate future growth and to provide a safer, more efficient route for everyone. While this change may limit access to the area for off-road vehicles, the improvements will help reduce traffic hazards and provide a safer environment for all road users, including pedestrians and cyclists, by including 6 foot shoulders.

We encourage the community to explore alternative areas specifically designated for off-road use for recreation.

Starting next week crews will return to Rathdrum to begin construction on State Highway 53 near the State Highway 41 intersection north of the railroad tracks.

The Idaho Transportation Department will construct an additional northbound through lane on SH-53 so that two lanes of traffic are able to move north through the intersection during green cycles. After construction SH-53 will still have a dedicated right turn lane for vehicles wishing to travel over the bridge.

The additional lane is intended to allow for more vehicles at a time to make it through the signal and help reduce the length of queued vehicles during peak hours.

During construction crews will close the existing right turn lane, meaning all northbound SH-53 traffic will make all movements from the one through lane. Drivers should also expect reduced speed limits and flagging. Any flagging for signal work will be done outside of peak hours.

Updates to traffic impacts and delays can be found using the Idaho 511 system either online, by phone or through the app.

Construction on the new U.S. Highway 95 four-lane segment between Moscow and Thorn Creek Road will resume this week. Drivers can expect to have one lane in each direction and slow down to 45 miles per hour in work zones mainly near Reisenhauer Hill until construction of five miles on the north end of the project is ready to accept traffic this summer.

Last year crews constructed nearly five of the six miles. They will now focus on paving the new alignment, building two bridges over Thorn Creek and connecting the new roadway to existing US-95. Construction on Thorn Creek bridges will continue in the fall.

The existing US-95 roadway will temporarily close at Reisenauer Hill in the summer as ITD switches traffic over to the new alignment. At that time, Latah County will assume ownership of the old route and plans to use funds from the Thorn Creek project to repave and reopen it.

“We have been running on all cylinders to deliver this vital safety project for our region,” District Engineer Doral Hoff said. “M.A. DeAtley Construction, Inc. and their teams are also eager to transform US-95 to four lanes so motorists can experience increased capacity for mobility and improved geometry for safety. We are appreciative of the public’s patience during this construction effort.”

Portions of this project are funded as part of Idaho Governor Brad Little’s Leading Idaho transportation funding initiative. The Leading Idaho money 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 communities across the state for years to come.

Travelers are reminded to check for live traffic impacts across the region including this one by visiting 511.idaho.gov, dialing 5-1-1 or downloading the app.

Starting next week drivers will be required to slow down and merge into a single lane in both directions as work resumes to reconstruct the Interstate 90 bridges over the Coeur d’Alene River near Cataldo. These bridges were first built in 1964 and are ready for replacement.

As early as mid-March all traffic will be shifted on to the westbound side of the interstate to allow crews to demolish and reconstruct the eastbound bridge. Next year, the westbound bridge is scheduled for replacement with traffic shifted to the new eastbound bridge. Work will end in late 2026.

River and trail users will also experience impacts during the 2025 construction season.

River Impacts

Beginning April 1 recreational access and use of the river, including boating, kayaking, tubing, swimming and fishing will be restricted for 500 feet on both sides of the bridges Monday through Saturday from 6 a.m. to 6 p.m. Boat launches outside of the work zone will remain available for use, though no one will be able to pass underneath the structure during working hours for safety reasons.

Construction will take scheduled breaks during the major summer holidays and access to the river will be available for recreation.

Signs will be posted locally at boat launches and access points that will update users of restrictions or changes throughout the construction process.

Trail of the Coeur d’Alenes Impacts

During construction trail users should be aware that there may be intermittent closures of five or ten minutes as equipment and materials are transported across the trail during day to day operations. Flaggers will be present during these closures to ensure safe crossing for crew members, vehicles and trail users.

Trail users should exercise caution in areas adjacent to the work zone for the possibility of loose dirt or gravel on the trail surface.

In 2024 a temporary work bridge was constructed across the river to provide crews and equipment access. Crossover lanes were also constructed on both ends of the work zone to allow for vehicles to be shifted during construction to maintain the flow of traffic.

 

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 expanding the freeway to four lanes between Post Falls and Coeur d’Alene, upgrading the I-90 State Highway 41 Interchange, and repaving from Wolf Lodge to Fourth of July Pass.

Drivers are encouraged to use the Idaho 511 system, either online, by phone or through the app, for updates on conditions and traffic impacts throughout the construction season.

Starting Monday, March 3, the Idaho Transportation Department will be making several significant changes to traffic near the Interstate 90 and State Highway 41 Interchange. These changes are necessary to accommodate ongoing construction efforts as ITD nears a major milestone of the project with the completion of the new Single Point Urban Interchange.

Additional changes to the westbound on-ramp are coming later this spring. Details will be shared as soon as they are available.

“Reconstructing the westbound off-ramp and improving SH-41 is a key part of the project’s success,” said project manager Randy Durland. “We thank the public again for their patience during these closures as crews continue to make significant progress towards the finish line.”

Construction on the new ramp and SPUI is expected to be complete in 2026.

Starting Monday, roadside construction will commence on U.S. Highway 95 between Riggins and the Time Zone Bridge to reduce the chance of rockfall. Workers will knock down insecure rocks and install rock anchors to stabilize the hillside above US-95.

Travelers can expect intermittent delays of up to 20 minutes while overhead debris is removed and anchors are installed. The travel lane width may be restricted in the work zone and slower speeds are encouraged for safety. Construction is slated to conclude through November.

Rockfall mitigation efforts remain a priority in this region because of the complex geology. This work will significantly increase safety by reducing the risk of future rock falls and prevent damage to the roadway.

The cost for the project is just over $1.6 million.

Live traffic impacts across the region from this project and others including construction near Whitebird can be found by visiting 511.idaho.gov. Travelers can also dial 5-1-1 or download the app.

The Idaho Transportation Department will reopen State Highway 21 between Lowman and Stanley at 8 a.m. on Friday. Traffic will be managed with a pilot car or flagging operation to safely guide vehicles through areas where crews are working on repairs.

ITD crews continue to work alongside emergency contractors to address the significant damage caused by the Wapiti Fire. This work includes clearing ditches, hauling materials to rebuild eroded hillsides, removing hundreds of hazardous trees, and replacing damaged guardrails. Once completed, steel guardrails that meet new modern standards will replace the burnt wooden rails.

Drivers are advised to avoid unnecessary trips and reminded not to stop along the highway, especially in the burn areas. Those traveling through the affected area should expect:

• Traffic guided by a pilot car or flaggers during active work.
• A temporary reduced speed limit of 45 mph.
• Significant delays when crews are working on the highway.
• Repair work continuing until weather conditions make further progress impossible.

The recent rain in the area has helped suppress the fire but has also caused slides and boulders to fall onto the highway. Due to the evolving conditions created by the wildfire, ITD advises drivers to always check 511.idaho.gov  before heading out.
