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.

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.

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.

 

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.
