ITD invites the public to join in “Operation Clean Sweep” along US-95

The Idaho Transportation Department is inviting community members to join a two-day litter cleanup effort along one of North Idaho’s busiest corridors. “Operation Clean Sweep” will take place April 23–24, covering the U.S. Highway 95 corridor from Granite Hill to Interstate 90.

This volunteer-driven event aims to remove accumulated trash and debris from the roadside as snow melts and winter’s impact becomes visible. Litter not only detracts from the natural beauty of the region—it poses risks to wildlife, the environment, and highway maintenance crews.

“Every year our work crews come together to tackle this large-scale cleanup initiative, and we thought it would be a great opportunity to let the public get involved—to work alongside the hardworking men and women of ITD and make a real, visible difference,” said Trent Bridges, one of ITD’s operations supervisors. “It’s frustrating to have to pull our crews off their regular maintenance work to deal with trash dumped by people who just don’t care, but unfortunately, it’s become a routine part of spring. Once the snow melts, the amount of litter we uncover is pretty overwhelming.”

Volunteers aged 16 and older are encouraged to participate and must register online ahead of the event.

Each morning, participants will check in between 7 and 9 a.m. at ITD’s Athol shed (6303 E. Parks Road) to receive safety gear, a brief orientation, and crew assignments. Work crews will be stationed along sections of US-95, and volunteers can stay for as long as they’d like—whether that’s a half hour or the full day. Cleanup will conclude each day by 4 p.m.

ITD will provide safety vests, trash collection bags, and safety instructions. Volunteers are encouraged to dress appropriately for the weather and bring gloves and water.

“Operation Clean Sweep” offers a great opportunity for students or individuals fulfilling community service project or volunteer hour requirements. ITD staff will be available to verify hours on-site.

Participants interested in ongoing involvement are invited to learn more about ITD’s Adopt a Highway program, a statewide initiative focused on long-term litter prevention.

Volunteers aged 16–17 must have a waiver signed by a parent or legal guardian. A printable waiver form can be found under the “Agenda” section of the event webpage.

I-90 bridge maintenance begins Monday in the Silver Valley

Map graphic showing the location of the three bridges that will be under construction on I-90 in the Silver Valley

Starting next week work will begin on three Interstate 90 bridges in the Silver Valley as crews work to carry out routine, preventative maintenance on the structures.

I-90 bridges west of Silverton over the South Fork Coeur d’Alene River
I-90 bridges at the Silverton Interchange
Wallace Viaduct

Through the work zones traffic will be reduced to a single lane of two-way traffic, and speed limits will be reduced to 55 miles per hour for safety. The Idaho Transportation Department will utilize crossovers constructed in previous years to shift traffic across the interstate allowing crews the space to work on these bridges.

This project will be carried out in two phases, the first addressing both sets of bridges near Silverton, and the second will focus on the viaduct in Wallace. Work on these projects is expected to be complete by late fall.

Information about intermittent ramp closures associated with the project will be posted locally, and in advance, on digital messaging signs along I-90. Up to date information will also be available to drivers through the Idaho 511 system.

Routine and preventative maintenance is essential to keeping roads safe, reliable, and cost-effective in the long run. Bridges are critical links in the transportation network, and like any structure, they experience wear and tear over time. By performing regular inspections, repairs, and upkeep now, the department can avoid more serious—and far more disruptive—problems down the road. These proactive measures help extend the lifespan of infrastructure, reduce the likelihood of emergency closures, and ultimately save taxpayer money.

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.

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.

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

Aerial view of Interstate 90 at the top of 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.

SH-54 right of way closure to motorized and non-motorized use ahead of highway expansion project

Aerial view of SH-54 and the adjacent ORV trail

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.

New lane at busy SH-53 intersection in Rathdrum to ease congestion

Traffic backed up at the intersection with cones

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.

Public invited to review proposed design for I-90, US-95 Interchange

The Idaho Transportation Department will host an open house next week in Coeur d’Alene to share information and gather input on the proposed redesign of the Interstate 90 and U.S. Highway 95 Interchange and associated local road improvements.

Date: Wednesday, March 5

Time: 4 p.m. – 7 p.m. (drop in anytime)

Location: Best Western Plus Coeur d’Alene Inn

506 West Appleway Avenue, Coeur d’Alene, ID 83814

The design is funded by Governor Little’s Leading Idaho initiative and is the first interchange project to emerge from the I-90 Corridor Study. The goal of the proposed design is to expand the interchange, enhance safety, and improve mobility to support future traffic volumes, which are expected to double by 2045. Ideas regarding the design for a future new interchange for I-90 and US-95 have been presented to the public through open house events of the past in 2022 and 2023.

The current design proposes several improvements, including a new single-point urban interchange, widening US-95, and grade separating US-95 and Appleway, among others.

For those not able to attend the open house in person, an online option will share the same information and be available starting March 5 at itdprojects.org/i90corridor. Comments submitted online before March 19 will be considered by the project team.

“The I-90 and US-95 Interchange connects two of the most traveled, and most congested, roadways in the region. Adding capacity and improving mobility on the interchange and adjacent roads will help to alleviate congestion, reduce crashes, and shorten commutes,” ITD Project Manager Joey Sprague said. “The intersection at US-95 and Appleway has the most crashes of any intersection in North Idaho. The proposed design will increase both vehicular and pedestrian safety and optimize interchange operations for decades to come.”

ITD is meeting with city officials, property owners and local businesses ahead of the public open house to present the design, answer questions and gather feedback. To stay up to date on this and other projects on the I-90 corridor, visit itdprojects.org/i90corridor and sign up for email updates.

Spring road restrictions go into effect on Idaho roadways

Sign notifying drivers of breakup limits in effect.

Sections of some state highways in Boundary County will find themselves under weight and speed restrictions starting at 6 a.m. tomorrow as regional weather trends begin to warm ahead of spring.

Immediate impacts to commercial vehicles will be:

US-95 from the US-2 junction to Eastport (milepost 511 to 538.56)

Commercial vehicles 10,000 gross vehicle weight rating and greater will be restricted to 30 miles per hour with legal axle weight

US-2 from the US-95 junction to the Montana state line (milepost 64.35 to 80.18)

Commercial vehicles 10,000 GVWR and greater will be restricted to 30 miles per hour with legal axle weight

SH-1 from the US-95 junction to Porthill (milepost 0 to 11.19)

Commercial vehicles 10,000 GVWR and greater will be restricted to 30 miles per hour and 14,000 LB per axle, or legal axle weight whichever is less

State Highways 200 and 57 in Bonner County will likely also see similar restrictions in place starting next week.

As the season changes, additional sections of highways across the entire Idaho Panhandle may have load limits and speed restrictions in effect. These restrictions are communicated with red/green indicator flags on load limit signs. Red means restrictions are in effect and large vehicles must follow the reduced limits. When green flags are out it means all traffic can flow without restrictions as the road conditions are more stable.

ITD crews closely monitor both weather and road conditions and make determinations about restrictions being in effect, which is why drivers may see them intermittently on and off as conditions change.

“These restrictions are put in place when the highways start showing signs of stress from the winter freeze/thaw cycle,” Boundary Foreman George Shutes said.

As the frost and ice thaw, they turn into water underneath the road, making the ground soft and highly vulnerable to damage. Large vehicles, because of their weight, push that water as they drive, almost like a wave moving through the layers beneath the road. This causes serious damage to the highway’s base and pavement, leading to cracks, erosion, and ultimately, the road breaking down much faster.

Slowing those vehicles down, and in some cases, limiting the weight, significantly reduces the stress on the roadway and prevents unnecessary damage like severe potholes. This not only protects the road from costly repairs, but also extends its lifespan, ultimately saving taxpayer dollars and ensuring safer driving conditions for everyone.

While restrictions are in effect, state law does not require large vehicles to pull over or allow cars to pass. This means that there is the potential for delays with reduced speeds along highway corridors.

“The best thing people can do this time of year is give themselves a little extra time to get from point A to point B,” Idaho State Police Sergeant Ron Sutton said. “Too often we see people get impatient and take unnecessary risks, like attempting to pass when it’s not safe, and those decisions can lead to disaster.”

Load limit restriction information is largely targeted towards commercial drivers on the 511 system, however that information is available to everyone by adjusting program settings. Drivers can find up to the minute road restriction information both online and through the app by following the steps below.

Online users can select the ‘Restrictions’ option under ‘Trucker Information’ on the menu on the right side of the page. See the first example below.

Mobile users can select the driver view setting to toggle into ‘Trucker view’ mode to view restriction information. See the second example below.

ITD announces new incident response program for the I-90 corridor in North Idaho

UPDATE: This service will now be on duty Monday – Thursday, 6 a.m. to 4:30 p.m., after further coordination with law enforcement.

The Idaho Transportation Department is excited to announce the launch of a brand-new Incident Response Vehicle program, which will begin operation next week to assist drivers along key corridors in North Idaho. This initiative is designed to enhance safety by providing rapid response to disabled vehicles, minor crashes, and other roadside emergencies, allowing motorists to get safely off the highway with minimal delay or risk to other drivers.

The IVR will primarily patrol the I-90 corridor, focusing particularly on work zones where limited shoulders and a lack of space pose more risk for travelers experiencing difficulties. These high-priority areas include ongoing construction projects at the State Highway 41 Interchange and the upcoming four lane expansion between Post Falls and Coeur d’Alene. Additionally, the truck will respond to incidents along the US-95 corridor stretching from the Spokane River Bridge to Lancaster Road through Coeur d’Alene.

The program will offer a wide range of services to assist drivers in need, including helping with flat tire changes, delivering small amounts of fuel for vehicles that have run out, jump-starting dead batteries, and even providing push or pull assistance for vehicles stuck in ditches following a crash or slide-off. The truck is fully equipped with the tools necessary to address minor maintenance issues and also has lights and signs to alert other drivers to a potential hazard while they work to clear the incident. Outside of keeping everyone safer, these free services are expected to save money by preventing costly congestion.

The new truck will be operated by a dedicated ITD operations employee and will be in service from Tuesday to Friday, between 6 a.m. and 4:30 p.m. The schedule was created based on data analysis of traffic volume and incident trends to maximize the program’s impact during peak hours and will be subject to change with the season.

“We are excited to bring this vital service to North Idaho,” said Ryan Crabtree, ITD Business Operations Manager. “By providing this dedicated vehicle, we are not only helping drivers get back on the road more quickly but also improving safety for everyone by reducing the risks associated with stopped vehicles in high-traffic areas.”

The new program builds on the success of a similar initiative in the Treasure Valley region of Southern Idaho, which has been operational since 1997. In fact, this initial vehicle was donated by ITD’s southern district. District One plans to add an additional incident response truck to its fleet later this summer

This new program also aims to support law enforcement agencies by helping to alleviate some of their non-emergency calls for traffic issues. With the addition of ITD’s Incident Response Truck, local law enforcement can focus on more complex and urgent matters, while ITD staff handle minor incidents and roadside assistance. For more critical traffic incidents that require police investigation, the IRV can help to provide additional traffic control to ensure the safety of first responders and other drivers on the road.

“We look forward to working closely with local law enforcement agencies to ensure a coordinated response to incidents,” Crabtree said. “This collaboration will help ensure that our highways are safer and that we are meeting the needs of the community.”

ITD encourages drivers to slow down and “move over” in accordance with Idaho law when emergency vehicles like this one are operating.

Anyone finding themselves in need of assistance, especially through the work zones or on busy roadways, should report emergencies to 911 or non-emergencies to local law enforcement.
