BOISE — The Idaho Transportation Department (ITD) will temporarily close Star Road in June as part of ongoing construction on U.S. Highway 20/26, (Chinden West), weather permitting. Work will include paving and intersection improvements and requires two separate closures.

In early June, Star Road between US-20/26 and State Highway 44 (SH-44) will be closed for approximately one week. The road will only be open to local traffic and emergency service responders (police, fire, and paramedics). Signage will direct motorists to use State Highway 16 (SH-16) between US-20/26 and SH-44 instead of Star Road.

In mid-June, a southbound detour will be in place between US-20/26 and McMillan Road with all work anticipated to be complete in early July. Again, the road will only be open to local traffic and emergency responders. Signage will direct motorists to use Can Ada Road and McMillan Road instead of Star Road.

Drivers should pay attention to all posted signs and message boards near this work zone.

I-84 westbound off-ramp at Franklin Road/US-20/26 (Exit 29) to close in early June

Beginning in early June, the westbound Interstate 84 off-ramp at Franklin Road (Exit 29) in Caldwell will temporarily close, weather permitting. Traffic will be detoured to the 10th Street exit and back onto US-20/26 by way of I-84.

This closure will allow construction crews to safely expedite reconstruction of the westbound off-ramp to reduce impacts to the traveling public and businesses later in the project.

A signed route will guide motorists through the detour and back onto US-20/26 by way of I-84 during the closure, which is anticipated to be in place until late July.

Please slow down, pay attention, and watch for posted signs and crews in the work zone.

Work on US-20/26 between I-84 and Middleton Road will continue through 2024.

Idahoans value work zone safety

Cones in truck

The Idaho Transportation Department is joining states across the country for National Work Zone Awareness Week. The national and state campaigns this week are designed to raise awareness and educate the public about the safety measures we can all take in work zones, and how we are all responsible for work zone safety.

From 2017 to 2021, Idaho saw 3,119 crashes in work zones resulting in 36 deaths, stressing the need for this year’s theme: “You play a role in work zone safety. Work with us.”

This special week includes a schedule of activities; everyone is encouraged to go orange for safety on Wednesday and observe a moment of silence on Friday for those who have died in work zones.

“Work zone safety is drivers and highway workers cooperating together to slow down and improve safety,” said Dan McElhinney, Chief Deputy and Chief Operations Officer for ITD. “ITD employees and contractors design traffic control with signs, cones, beacons or reduced speed limits to help guide vehicles through these hazard zones, knowing we really appreciate drivers being engaged without distractions for success. Let’s all get home safely every day.”

Work zone crashes are preventable. The top three causes of crashes from 2017 to 2021 were following too closely, distracted or inattentive driving and failing to yield.

Drivers should:

  • Plan ahead – Check before you go to plan your route. Expect delays, leave early or take an alternate route if possible.
  • Slow down– drive the posted speed limits.
  • Pay attention– both to workers directing you and surrounding traffic.

Repaving of Eagle Road resumes this month; nightly detours begin Monday, April 17

Eagle Road Repaving Project

The Idaho Transportation Department will resume repaving work on Eagle Road this month between Interstate 84 and State Highway 44. Portions of Eagle Road will be detoured at night starting Monday, April 17. All work is weather dependent.
This year, crews will repair the road surface on Eagle Road and several intersections between I-84 and SH-44, including McMillan Road, Ustick Road, and Fairview Avenue. This is the second season of a two-year project.

During the week of April 10, crews will begin preparation work and one lane will be closed on Eagle Road at night. Starting April 17, all lanes of Eagle Road will be detoured each night where crews are working.

Between Franklin Rd. and Chinden Blvd.:

  • Traffic will be detoured to Locust Grove Road or Cloverdale Road

Between Chinden Blvd. and SH-44:

  • Traffic will be shifted to one side of Eagle Road

At the McMillan, Ustick, and Fairview Intersections:

  • Traffic will be detoured to Locust Grove Road or Cloverdale Road

Overnight closures and detours will begin at 10 p.m. and end at 6 a.m. on weekdays. Weekend opening times will vary between 6 a.m. and 9 a.m. depending on traffic volumes. All lanes will be open during the day. For the latest closure information, text EagleRoad to 1-866-483-8422 or visit

“We have a lot of ground to cover this construction season, so we ask that drivers slow down and be cautious where crews are working,” said Jeff Ryan, ITD Design/Construction Engineer. “Nighttime closures will help keep crews safe and keep all lanes open during the daytime commute.”

Temporary steel plates will be placed on Eagle Road to cover manholes until the project is complete. Please drive with caution.

Last season, crews repaved the roadway near I-84 and Island Woods Drive. All construction is expected to be completed in fall 2023.

Idaho Materials & Construction is the contractor for this $18 million project.

SH-21 to close tonight north and south of Lowman for avalanche risk, drifting

Barricades up to close SH-21 at milepost 48 in November of 2022

The Idaho Transportation Department will close State Highway 21 north and south of Lowman tonight at 6 p.m. as a major storm system brings heavy snow, high winds and avalanche danger to the region.

The highway frequently closes between Lowman and Stanley from Grandjean to Banner Summit, but another section will also close south of Lowman from milepost 70 to milepost 48 near Idaho City.

“This storm could deliver up to two feet of fresh snow, and with wind gusts near 25 miles per hour, we are expecting next to no visibility and drifting, making it too dangerous to travel,” Field Operations Manager Eric Copeland said. “For those reasons, we are closing both sections of SH-21 this time.”

Based on forecasted weather, the highway could reopen sometime on Saturday, March 11. Drivers should check and ITD’s Twitter account for updates before traveling.

Plans for addressing the pothole problem on Broadway Ave. in Boise

BOISE – The Idaho Transportation Department is aware of the poor pavement condition on Broadway Avenue in Boise and is working to address the issue. Winter weather has accelerated the roadway surface separating from the pavement underneath, resulting in many large, shallow potholes.

ITD is working to address the pothole problem on an ongoing temporary basis, as well as with a permanent repair planned for this summer. The temporary repairs consist of filling the holes with “cold patch” material, but that has proven challenging as the potholes are shallow enough that the material quickly becomes displaced. None the less, maintenance crews will continue to target those potholes that will hold the patch material.

Permanent repairs will be performed once weather allows later this year. ITD is accepting bids to repave Broadway Avenue from I-84 to Beacon/East Park Boulevard. The project is scheduled to kick off this summer and will ultimately provide drivers with a new, smooth roadway surface.

ITD appreciates the public’s patience and is working diligently to start repaving Broadway Avenue as soon as possible.

Canyon County bridge repairs begin in late February

Repairs to the Interstate 84 Galloway Road overpass in Canyon County

BOISE – Repairs to the Interstate 84 Galloway Road overpass in Canyon County will begin in late February and will include overnight interstate detours for westbound motorists.

The overpass, located between State Highway 44 (Exit 25) and Sand Hollow/Oasis Road (Exit 17), will be fully closed during this work to repair damages due to a large truck hitting the structure.

During some overnight work, westbound I-84 traffic will be detoured off the interstate at SH-44 and up Old Highway 30 to the Sand Hollow/Oasis Road interchange and then back onto I-84.

Advanced notification of those detours will be posted on I-84 near the work zone and on and on the 511 app.

“Safety is our highest priority,” said Idaho Transportation Department (ITD) Project Manager Justin Wolf. “Please watch for flaggers and other crews working in the area and follow all posted signs.”

Drop-in meeting on Feb. 22 for SH-16 construction

new I-84 interchange construction

NAMPA – The Idaho Transportation Department will host an informal drop-in meeting near the State Highway 16 construction zone on Wednesday, Feb. 22. Project staff will be on hand to answer questions from 3-6 p.m. at the Holiday Inn Express at 4104 E. Flamingo Avenue in Nampa.

ITD is extending State Highway 16 between U.S. Highway 20/U.S. Highway 26 and I-84, west of McDermott Road. Drop-in meetings have been held every three months during construction, which began in 2022.

Eight snowplows hit this season; ITD calls on drivers to be more cautious

Side-by-side images of a disabled plow on the side of the road.

So far this season across Idaho, drivers have caused eight crashes with snowplows. As more winter weather moves across the state, the Idaho Transportation Department (ITD) wants to remind drivers how to be safe around snowplows.

1. Never pass a plow on the right. Plows have a smaller wing plow that extends from the right side of the vehicle, which can be hard to see when the snow is flying. Drivers passing on the right and hitting the wing plow is the most common plow-related crash.
2. Give plows room to work and avoid their blind spots.
3. Be patient. The safest place to be is behind the plow.
4. Plows often work in tandem to clear multiple lanes. Never get in between the tandem plows.
5. If you are involved in a crash or stopped on the side of the road for any reason, please remain in your vehicle for your safety and for the safety of our plow operators.

The seventh and eighth crashes happened today in North Idaho, and both involved tandem plows. This morning on Interstate 90 in Coeur d’Alene, a driver got between two plows as they merged onto the highway. The driver then hit the brakes, forcing the second plow off the road to avoid a collision. Then around lunchtime on U.S. Highway 95 south of Athol, a driver passed the first plow on the left and then struck the second while trying to pass on the right.

Both plows are now out of service for the current storm.

“This issue affects everyone, not just the people involved in the crash. Every plow that is hit causes a domino effect making conditions worse,” said Operations Foreman  Shannon Thornton. “There are fewer plows on the road to deal with the snow that is still falling, and our crews have to spend precious time recovering equipment instead of plowing.”

Last winter, there were 11 plow strikes, an increase from years past and a number that ITD does not want to repeat. Please be careful driving and mindful of our plows. Check or the Idaho 511 App for road conditions before traveling. For more winter driving tips, visit

The Dos and Don’ts of driving near snow plows

Plow clearing SH-6 near White Pine Campground

Snow has already fallen in the state, so drivers should get ready to drive with plows this winter. Talking about sharing the road with plows is really more of a discussion on what you shouldn’t do.

What shouldn’t you do?

Don’t pass. The road behind a plow is always better than the road in front of a plow. And all the snow, rock and other debris comes out of a plow at a high rate of speed––if you pass and try to drive through all that, the weight of the snow could force your vehicle off the road or break windows.

Of course, that’s assuming you don’t run into the plow while attempting to pass it.

Plows trucks weigh up to 58,000 pounds and sport not one, but two, plows. Everyone is familiar with the plow on the front, which is 12 feet long and takes up a whole lane. People tend to forget about the second, smaller plow positioned on the right side of the truck. It’s called a wing plow.

That’s the one folks run into. When plows are pushing snow, it comes up over the top of the plow and obscures all the lighting and flags. Again, plows weigh up to 14 times the average vehicle, so running into them is going to have an impact.

While not illegal to pass a plow, it’s recommended you never do so on the right side because of the wing plow. Law enforcement can and will cite drivers who act recklessly or carelessly and pass when it isn’t safe.

Operators will often work in pairs, especially on multi-lane roadways like freeways, to get snow pulled from the far left side all the way to the shoulder. Don’t try to pass several plows at once or drive between them.

Plows are large vehicles with blind spots, even when not working in blizzard conditions or pushing snow. Stay out of their blind spots.

If you’re going to pass, it’s important to consider where the snow is going. Our drivers typically push snow to the right, but in some cases, they will push snow into the median.

Sometimes there isn’t room to push snow into the median, or there aren’t enough operators available to tandem plow. You may see a plow working by itself on a freeway, pushing snow into the fast lane on the first lap and then moving it all the way off the roadway on a second pass. There may be enough room to pass safely on the right – but first slow down and observe where the snow coming out of the plow lands on the road before you make your decision.

When in doubt, don’t pass.

What should you do?

  • Drive for conditions. The posted speed limit is set based on ideal conditions, so in winter you’ll have to slow down. It’s on the driver to determine a safe speed.
  • Maintain at least a three-second following distance. On slick roads, you’ll need more time to react and stop if necessary.
  • Move over. Any time emergency vehicles—which include tow trucks—are flashing their lights, you are legally required to slow down and move over into another lane if possible.
  • Leave early. Giving yourself extra time will make it that much easier to make smart decisions.
  • Download 511. No need to guess what your route looks like – download the 511 app or visit to see road conditions and if there are any reported crashes.

As you head out on the road this winter, keep these safety tips in mind so that you and our plow drivers can make it home safely.
