Beginning Monday, the Idaho Transportation Department will build a traffic island on U.S. Highway 91 (Yellowstone Avenue) at Bullock Street in Chubbuck to reinforce existing restrictions that prohibit unsignalized left turns onto Bullock Street.
Yellow tubular markers will be removed and replaced with the concrete island over the next two weeks, depending on weather.
During construction, the southbound left turn lane from Yellowstone Avenue to Breneman Street and businesses like Walmart will be closed. The leftmost northbound lane on Yellowstone will also be closed to provide enough room for crews to work.
BOISE – On Tuesday, April 8, ITD will provide training and guidance to suppliers and those seeking to have their materials and products used in highway construction projects added to ITD’s Qualified Products List. The training will be done via a live video which will reside on ITD’s website for several weeks following the live session.
The QPL streamlines the process of testing, evaluating and approving products commonly used on highway construction projects. Rather than evaluating products to determine acceptance for each new project, products proven to meet our specifications are categorized and listed on the QPL.
Although the QPL hasn’t changed, the process of interfacing has been improved and streamlined, so the session on April 8 will demonstrate how it is to be used. The training/demonstration will be held from 11-noon Mountain Time. Project suppliers, distributors, and their agents can access the training through Microsoft Teams by various means listed bat the bottom of this page.
The session will be recorded. If you are unable to attend this demonstration, the recorded presentation can be found at the QPL webpage on our ITD website here:
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.
RIGBY— With the onset of spring, over the next several months the Idaho Transportation Department and contractor partners are crack sealing, repairing potholes, removing hazardous trees and conducting more substantial improvements to ruts and bumps in the roads from Salmon to Driggs and the Montana state lines to Idaho Falls.
Crack sealing is underway on Interstate 15 from Idaho Falls to Dubois, as well as State Highways 33 and 47. This work involves a mobile one-lane restriction that follows workers’ progress. ITD crews fill minor cracks in the roadway with a strong, sticky tar that serves to keep water from getting under the surface and making the damage worse. This must be done in spring during cooler temperatures and dry conditions, and then the repair effectively expands through warmer months.
Flagging operations will be in place temporarily on state highways across east Idaho as ITD performs mastic pothole repair. Expect flagging delays to be less than 15 minutes where this work is occurring. Mastic work uses a hot-applied rubber and asphalt combination that is highly effective at sealing up more substantial damages in the road. These fixes must also be done in dry conditions and specific temperatures seen during the spring. Crews time work before or after peak travel times, even at night as needed.
On U.S. Highway 20 between Rexburg and St. Anthony, crews will be working to mill off the surface of the road in 1,500-foot stretches or less and then overlay new pavement. Expect to see one lane closures and speed reductions where this is occurring.
Hazardous tree removal will also begin this spring on U.S. Highway 93 between Challis and Salmon. ITD crews can sometimes work off the roadway, though flaggers will be in place as needed, with one lane restricted in 15-minute increments. The removal of dying and diseased trees will improve errant driver safety recovery zones, wildlife visibility and fire protection widths. This effort will continue through the spring and into the summer months.
Other routine spring maintenance work like shoulder repairs and delineation enhancements are also ongoing. Drivers should be aware of these smaller work zones, slow down and move over to help everyone stay safe. Download the Idaho 511 app or visit tps://511.idaho.gov/ to stay up to date on where road work is occurring across Idaho.
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 16th 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.
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.

Critical repairs on US-95 to begin Monday – two shifts per day to accelerate work
Full closure on U.S. Highway 95 between Council and New Meadows will begin Monday. The contractor will be working two shifts per day to expedite the repairs and minimize the closure time.
The Idaho Transportation Department has carefully considered all potential detour options, including local roads, to minimize the impact on travelers. After exhaustive evaluation, it was determined that no local routes are capable of handling the heavy traffic diverted from US-95 due to early-season conditions and challenging terrain. To mitigate disruption, ITD recently cleared snow from the Weiser River Trail, which will serve as a bypass for local pedestrians and emergency responders. This trail provides a direct route around the closure. Designated parking on US-95 will be available on the north and south side of the landslide, ensuring residents and emergency personnel can continue to navigate the area safely. Additional details will be shared with businesses and local jurisdictions as we monitor trail demand.
Beginning Sunday evening at 8 p.m., US-95 will be fully closed to all vehicle traffic due to the oversized drill rig crane taking up both lanes. Crews will begin relocating fiber optic lines on Monday, followed by the start of excavation on Tuesday for the installation of a retaining wall. The excavation will involve removing 200 feet of pavement and digging to a depth of 10 feet across a 200-foot-long section of roadway. This work is scheduled to be complete by late April or early May.
ITD has modified commercial vehicle permits, allowing 53-foot single trailers to temporarily use State Highway 55 as a detour. This modification ensures that rural communities continue to receive deliveries of goods and services during the closure. ITD is coordinating all work on SH-55, which serves as the detour route for regional traffic. Maintenance projects that were slated to begin this spring will be postponed until US-95 is reopened.
Regular updates on the roadwork and closure will be available on 511.idaho.gov, through the 511 app, or by calling 511. ITD remains committed to restoring US-95 as quickly as possible while minimizing the impact on local communities and businesses.
3/26/2025
The weight limit for vehicles traveling near the slide area has been increased to 26,000 lbs., up from 10,000 lbs. This change will remain in effect until Sunday’s closure.
3/26/2025 Equipment to be mobilized to US-95 landslide, full closure set for Monday
Equipment is being mobilized to begin permanent repair work on the U.S. Highway 95 landslide located between Council and New Meadows at milepost 146.5, about ten miles north of Council. Workers have been on-site since the hillside gave way last Sunday due to steady rainfall.
A full closure of US-95 to all vehicle traffic will be implemented starting Sunday evening at 8 p.m. Until then, flaggers will direct local non-truck traffic through one narrow lane during daylight hours, from 7 a.m. to 8 p.m. After the closure on Sunday evening, the road will remain closed, as the contractor’s equipment will require both lanes for earthwork removal and wall installation.
On Monday, crews will begin excavation of a 200-foot-long, full-width section of the roadway, digging to a depth of 10 feet. Once excavation is complete, construction will begin immediately. The repair project will include a retaining wall, which will be anchored by steel piles driven into the stable rock layers of the slope. The highway is expected to reopen in early May once the work is completed.
There are no local detours that are passable this early in the season, and no local routes suitable for the impact of highway traffic. The Idaho Transportation Department has modified permitting for commercial vehicles to allow companies to safely operate on SH-55 to continue delivering goods to rural communities. This temporary exception allows 53-foot single trailers to use SH-55 as a detour for now.
ITD is working with emergency responders to ensure uninterrupted service for all areas. ITD is also working with local jurisdictions to identify potential alternatives for local workers to get past the US-95 closure.

ITD modifies permitting for commercial vehicles on US-95 to ensure continued delivery of goods
In response to restrictions placed on U.S. Highway 95 between Council and New Meadows following a landslide on Sunday, the Idaho Transportation Department has modified permitting for commercial vehicles to allow companies to safely operate on State Highway 55 and continue delivering goods to rural communities.
The temporary exception allows 53-foot single trailers to use SH-55 as a detour for now. Given the narrow and winding conditions on SH-55, only certain combinations of trucks and trailers are typically allowed.
Drivers should expect more traffic on SH-55 with the current restrictions on US-95 and expect commercial vehicles to potentially slow down or stop near the Rainbow Bridge as they will be directed via signage to yield to oncoming traffic.
For 24/7 updates on the status of US-95 and SH-55 visit 511.idaho.gov, download the 511 app or call 511 for updates.
One lane temporarily open for local traffic only through US-95 slide near Council
One lane of U.S. Highway 95 is now temporarily open at the slide at milepost 146.5 north of Council. This lane will only be for local traffic and only open during daylight hours between 7 a.m. and 8 p.m. until contractor equipment begins work next week.
The highway will fully close each night as crews will only visually monitor the route during daylight for slumps or cracks that could indicate another slide.
Commercial vehicles will not be allowed on the route to avoid the narrow road. Flaggers in New Meadows and Council will direct these vehicles to turn around. The Idaho Transportation Department is working on modifying the permitting process to allow for commercial vehicles to take State Highway 55 instead. Drivers should expect to see more trucks on SH-55 and practice patience.
The engineering team is reviewing data from foundation drilling yesterday and are expecting a design of a retaining wall by Tuesday that will be anchored by steel piles driven into the stable rock layers of the slope. This data will tell the team where and how deep to drive the steel piles, and land surveyor data collected the last few days will identify the full size of the slide for wall length and height design.
ITD has a prime contractor at the ready and will be working simultaneously with the design team to secure materials and any subcontractors prior to the repairs starting next week.
There are no local detours that are passable this early in the season and able to withstand the impact of highway traffic.
ITD will issue another update next week once the design for the repairs has been completed and future impacts to traffic are better known. Drivers may not be able to pass through the slide area once repairs are underway given the size of equipment that will be on site. The highway will likely be impacted through late April.
Workers have been on scene since the hillside gave way on Sunday following steady rainfall.
For 24/7 updates on the status of the highway, visit 511.idaho.gov, download the 511 app or call 511 for updates on this closure.
US-95 remains closed between Council and New Meadows
Guardrail hangs above a washed-out embankment
U.S. Highway 95 remains closed between Council and New Meadows due to a few hundred feet of downhill landslide of the roadway shoulder at milepost 146.5 along the Weiser River on Sunday afternoon following steady rainfall.
Engineering crews were on site this morning to assess the extent of the damage for repair decisions, and a drill crew will be on site tomorrow morning to investigate soil and slide information for a possible retaining wall.
“We aim to have one lane opened at some point this week, but just for cars,” District Engineer Jason Brinkman said. “We are concerned about allowing wider, heavier commercial vehicles on this narrow area until the repair work is complete.”
Regional traffic is encouraged to take State Highway 55 as no traffic is allowed through the landslide location. Only people who live between Council and Glendale south of the slide and between Pine Ridge and New Meadows north of the side will be allowed to access those areas. All other drivers are being turned around at the barricades in Council and New Meadows.
This particular area was already being monitored by the Idaho Transportation Department for storm damage concerns.
“These natural weather events are nearly impossible to predict,” Brinkman said. “Fortunately, given this season of storms, we are ready to respond and expedite this project.”
Getting the highway back open fully could take weeks. Motorists should visit 511.idaho.gov, download the 511 app or call 511 for updates on this closure.
The Idaho Transportation Department has begun crack sealing US-91 in Pocatello. Work began Monday on 5th Street and has continued onto 4th Street. Crack sealing north through Pocatello on Yellowstone Avenue will continue as weather permits.
“Once we reach Cedar Street, we will shift to nighttime work to minimize disruption to businesses,” said Pocatello Foreman Anthony Richards. “Other than where the pavement is concrete, we’re planning on continuing north all the way to Walmart.”
The sealant prevents water from entering the pavement causing further erosion and extending the lifespan of the road
Motorists should expect single lane closures in the work zone.
Drivers are encouraged to use the Idaho 511 system for traffic impact updates for this project, and all ITD projects statewide.
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.

Idaho businessman Paul Franz was announced as the newest member of the Idaho Transportation Board Thursday (March 20) at their monthly meeting in Boise. He replaces Jim Thompson, who left the board when his term expired at the end of January after nearly six years.
Franz will represent the five northern Idaho counties. He comes to the board with a background as a professional engineer and former performance manager, in addition to having a strong record of community involvement. In making their announcement a day earlier, Governor Brad Little said, “Paul Franz has the personal and professional qualities to help Idaho advance historic investments in transportation to keep up with the needs of our rapidly growing state.”
“I’m really looking forward to working with Paul on the important transportation issues of a growing state. His engineering and management background will be an invaluable resource as we address these statewide needs,” said Idaho Transportation Board Chairman Bill Moad.
Paul was employed by CPM Development for 42 years until his retirement March 7. CPM is a major Pacific Northwest supplier of concrete, asphalt and aggregates. Franz was President of the Idaho Association of General Contractors in 2007 and has been a board member of the Idaho AGC for the past 22 years.
Franz graduated from the University of Idaho with a Bachelor of Science in Civil Engineering. He and wife, Elizabeth have been married for 41 years and have six adult children.
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.
