Weekend traffic relief coming to I-90 Veterans Memorial Bridge project

Drivers using Interstate 90 over the Veterans Memorial Bridge in Coeur d’Alene will start to see some weekend relief from lane closures as construction continues on one of Idaho’s most iconic and highly traveled bridges.

Earlier this summer, crews began working on the bridge as part of a larger project to repair and preserve several bridges across the Panhandle. Because I-90 is such a busy route, lane closures were needed to give workers and equipment a safe space to operate. The Veterans Memorial Bridge is a large structure, and repairs require specialized tools and setup. Up to now, full-time traffic control has been essential to keep crews safe.

Now that the project has reached a key milestone, crews are able to adjust how they manage traffic. Starting this weekend, ITD will begin reopening all four lanes—two in each direction—on weekends. Traffic control devices will be removed Friday through Sunday evenings, and the interstate will return to its regular configuration. Lane closures will go back into place during the week so crews can continue working.

Some drivers have asked why the bridge has been reduced to one lane in each direction even when it looks like no one is working. The reason is that much of the work is happening underneath the bridge. Workers are using scaffolding and equipment that hangs over the side of the bridge deck to access the areas that need repairs. So while you might not see people on top of the bridge, important work is still being done out of sight to improve the structure and keep it safe for years to come.

ITD expects the project to wrap up by the end of August. In the meantime, drivers are asked to watch for changing traffic patterns, be alert in work zones, and remain patient as crews complete this important work.

Road striping to impact US-95 this Sunday through Coeur d’Alene

Drivers traveling U.S. Highway 95 through Coeur d’Alene on Sunday should expect slower traffic and possible delays as crews with the Idaho Transportation Department paint the highway lines between Lancaster Road and the Spokane River Bridge.

Crews will begin work early around 6:30 a.m. and expect to finish by 4 p.m. This is a high-traffic area with many intersections and signals, so extra caution is needed.

To help keep everyone safe our partners at the Idaho State Police will assist with additional patrols in the area. Drivers should be patient, give the paint crew plenty of space, follow posted signs, and avoid crossing over wet paint lines.

 

Upcoming striping schedule (weather & conditions permitting):

July 21–28: Boundary County

  • US-95
  • SH-1
  • US-2

July 29–31: SH-53 from the Washington state line to US-95

August 4–6: SH-41 from Mullan Ave to Rathdrum

August 6–18: US-95 from the Spokane River Bridge south to Sanders Road

Additional routes like SH-58 and SH-60 may be added to the schedule as time allows.

 

Why striping happens during the day

Many drivers ask why this work isn’t done at night to avoid traffic. The answer is simple: paint needs light and warmth to be applied safely and effectively. Striping requires clear visibility and vehicle lights aren’t enough for crews to paint accurate lines. Cooler nighttime temperatures in North Idaho can also prevent paint from drying properly, leading to poor adhesion and safety issues.

Some larger cities can stripe at night because of extensive street lighting, but those conditions don’t exist along most of our routes in North Idaho.

 

Sharing the road with striping crews

  • Don’t pass striping crews or drive over fresh paint. This not only damages the lines but can also damage your vehicle.
  • Watch for “wet paint” signs and pace cars. These guide the flow of traffic and help protect workers.

Be patient. Crews work as quickly and safely as possible to minimize disruptions while ensuring proper application of the paint and reflective beads.

ITD paints hundreds of miles of highway each year. The lines help guide drivers safely down the roadway and improve visibility, especially at night. Your cooperation helps us do this work safely—for you and our crews.

Work at Macks Inn Bridge along US-20 beginning Monday

Macks Inn Bridge on US-20 through Island Park, Idaho.

 

Work to improve and repair the Macks Inn Bridge on US-20 through Island Park will begin on Monday. Crews are customizing handrails, repairing guardrails and installing concrete railings to improve safety for multiple uses in this popular location. These efforts are expected to be completed by Thursday of next week. If needed, finishing work will resume the week following but will not be in effect through the weekend.

One lane of traffic will remain open in each direction throughout this project, with the lane nearest the bridge closed one side at a time. Turning movements to and from businesses and river access will be monitored and allowed to be made as normal.

Drivers can expect to see large equipment on site to correctly locate a sewer line near the bridge. Travelers and recreationists are urged to observe lower speed limits and stay engaged while driving. Be aware of workers and equipment very near open travel lanes.

Updates for this project and others across Idaho can always be seen on the Idaho 511 app, or at 511.idaho.gov.

On Friday the Idaho Transportation Department will shift traffic from existing State Highway 54 to the new section of pavement between SH-41 and Ramsey Road.

Drivers will be routed onto this new section of roadway while crews begin rebuilding the existing lanes. During this time, the speed limit will be reduced to 45 mph and passing will not be allowed for the remainder of the construction season.

In the coming days and weeks, access to side streets and driveways in the area will be temporarily closed as crews work directly in front of them, but closures will be short and only in place as long as necessary – likely an hour or less. Drivers should pay attention to local signage for closures and detour routes as work rolls through the area.

This traffic shift marks a key milestone in the ongoing highway improvement project which is on track to be completed in 2026.

Drivers are urged to use caution in the area and watch for flaggers and signs.

Idaho 511 is available as a resource to provide updates on construction impacts and road conditions state-wide.

Drivers urged to slow down: regional speed crackdown happening July 20–26

BOISE — The Idaho Transportation Department’s Office of Highway Safety (OHS) is reminding drivers to slow down as law enforcement agencies across the state ramp up speed patrols this month.

This effort, taking place July 20–26, is part of a broader regional campaign in partnership with neighboring states Washington, Oregon, Montana, and Alaska. With coordinated patrols across state lines during this time, drivers should expect to see an increased law enforcement presence wherever their summer travels take them throughout the Northwest.

“Speed limits are not suggestions—they’re there to save lives,” said Josephine Middleton, ITD Highway Safety Manager. “Slowing down gives you more time to react and reduces the severity of crashes.”

So far this year, 126 people have died on Idaho roads, up from 113 at this time last year. During the “100 Deadliest Days” between Memorial Day and Labor Day, Idaho has seen 49 fatalities in 2025, compared to 40 during the same period in 2024.

Drivers are reminded to follow posted speed limits, allow extra travel time, and adjust speed for weather and traffic conditions.

Public invited to give input on corridor improvements along Chinden Boulevard

Map of the corridor being studied.

The Idaho Transportation Department, in partnership with Garden City, invites the community to attend an online meeting to learn more about a study to develop a stormwater drainage plan and identify corridor improvement projects. Future projects may include multi-use pathways that serve pedestrians and cyclists and other active modes along Chinden Boulevard.

The online self-guided meeting will be available from July 18 through August 1 at https://itdprojects.idaho.gov/pages/chinden-drainage-and-design.

The online meeting provides the public with an opportunity to review and provide feedback on study concepts for improved water management systems and future projects to enhance connectivity and mobility along the corridor.

The study aims to develop an integrated corridor plan to guide development and identify specific projects for future planning, design, and construction. This unified plan will ensure that consistent drainage and multi-modal facilities, such as sidewalks and bike lanes, are included with each new construction project along the corridor.

Currently, funding has not been allocated for future Chinden Boulevard improvement projects. Final recommendations and cost estimates are scheduled to be completed early in 2026.

Community invited to view future SH-16/44 Interchange plans

The Idaho Transportation Department invites community members to learn about the future State Highway 16 and State Highway 44 Interchange at a public meeting Thursday evening. Construction will begin this summer to replace the current intersection with a new interchange design that includes ramps to help drivers get on and off the highway more safely and easily.

Community members may participate in person Thursday, or online July 17-31, to learn about anticipated traffic impacts and how to stay informed during construction.

“The new interchange at SH-16 and SH-44 will address growing traffic demands in the Treasure Valley,” Project Manager Styles Salek said. “This interchange will also help reduce congestion along West State Street [SH-44], a heavily traveled route for commuters and travelers alike.”

The interchange is part of ITD’s long-term vision for State Highway 16. The first phase of highway improvements, that included highway widening, were completed in 2014 between US-20/26 and SH-44.

Funding for this project comes from the Idaho Transportation Expansion and Congestion Mitigation bonding program. The program allows ITD to accelerate project timelines to address rapid growth and build critical infrastructure today that would otherwise take many years to complete.

Historic System Interchange rebuild nearing successful completion

With the painting of final lane markers on the new roadway, construction at the I-86/I-15 “Flying-Y” System Interchange in Pocatello is coming to a successful conclusion. Begun in July 2022, the three-year $112 million project has dramatically changed the drivability of the interchange.

“We spent over eight years from design to actual construction of the project. We’re pretty proud of it. It’s one of the bigger projects we’ve designed. It’s one of the largest projects ever designed entirely by ITD staff and inspected with ITD personnel. Most of the people on the team live here locally and this has been a really meaningful project for us to make sure we did our very best,” said Project Engineer Aaron Baird.

Critical areas that were improved include the northbound Pocatello Creek on-ramp, the northbound-to-westbound collector distributor, and the eastbound-to-northbound ramp. Each of those improvements made merging from one Interstate to the other smoother and safer for motorists.

“We’re excited for people to use the final product. We hope it’s something that will last a long time and keep the travelling public safe as they use it,” said Project Manager Greg Roberts.

The scale of the endeavor has been truly historic. Approximately 1 million cubic yards of excavation have been completed. In addition, about 490,000 tons of base material was brought in; 116,000 tons of asphalt were placed; and over 7,700 cubic yards of concrete were poured. Nearly 70,000 square feet of retaining walls were also built throughout the project area. Finally, ITD built eight new bridges. Four of those have precast concrete girders and four have steel girders. In all, over 5 million pounds of steel has been used in the new bridges.

Construction crews worked year-round and around the clock for approximately three years to complete the project. To minimize disruption to traffic, key demolition operations were conducted at night. These efforts minimized the impact on traffic while the interchange was being reconstructed.

In addition to the major changes inside the Flying-Y design, the Chubbuck Road overpass was reconstructed as an underpass to improve site distances and vertical clearance on I-15, and to improve access to the Wellness Center from Chubbuck. The new underpass is significantly wider and includes bike lanes and sidewalks.

ITD also worked closely with the Portneuf Greenway to construct a pedestrian and bicycle path on the east side of the worksite to connect the Greenway to the Wellness Center.

Work left to wrap up the project will be off the roadway and conducted on the shoulders. In addition, ITD will be seeding open ground with native grasses.

“Thank you for being patient with us and seeing our vision, seeing what we’re trying to do to positively impact this community,” said Project Manager Zak Johnson.

District Engineer Todd Hubbard echoed those sentiments, “This project has been a great success and is an important addition to the community for the safety of drivers. It has been a lot of work to get all of it completed and to keep traffic moving. I want to thank everyone for their patience as we have worked on this project over the last three years. And a thank you to the project team and Sundt-Cannon Joint Venture for a project well done.”

Drivers are encouraged to remain attentive, move over for workers and emergency vehicles, and follow posted speed limits.

Major traffic changes on westbound I-84 in Caldwell start Sunday

Aerial view of traffic on Interstate 84 in Caldwell

The Idaho Transportation Department will change the traffic pattern on westbound I-84 in Caldwell starting Sunday night. Westbound motorists are advised to drive with caution and follow signage.

Under the new traffic pattern, westbound traffic will split into two lanes just after the 10th Avenue Interchange. The right lane will allow drivers to either continue west or exit at Centennial Way, while the left lane will continue westbound with no access to the exit. Once the lanes split, there will be a physical barrier between them, and drivers will be unable to change lanes. Motorists should pay close attention to signage and make sure they are in the correct lane before the split, especially if they plan to exit at Centennial Way. The lanes will merge back together just after the Centennial Way Interchange and westbound traffic will return to its regular configuration. Click here to view a map of the traffic change.

To set up the traffic changes, crews will close the westbound off-ramp at Centennial Way the night of Sunday, July 13 from 10 p.m. to 5 a.m. Motorists will be detoured to Exit 26 where they can then return on I-84 eastbound to exit at Centennial Way. Click here to view a detour map.

In early August, crews plan to move into the next phase of construction. Westbound traffic will return to the westbound side of the highway and ITD expects to reopen the 10th Avenue westbound on-ramp at that time. The ramp was closed in June to reconstruct the westbound lanes on I-84.

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 construction zone is 55 miles per hour. Drivers should slow down, pay attention and follow all posted signs. Crews and heavy equipment will be working close to traffic.

Construction is expected to be finished in 2027. For more information and to sign up for email or text updates, visit itdprojects.idaho.gov/pages/i-84-corridor or call (208) 334-8002.

Drivers can also use Idaho 511 to check for real-time traffic impacts related to construction projects and road conditions statewide.
