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 511.idaho.gov 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 511.idaho.gov 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.”

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 511.idaho.gov or the Idaho 511 App for road conditions before traveling. For more winter driving tips, visit itd.idaho.gov/travel.

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 511.idaho.gov 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.

ITD to show design plans for I-84, Centennial Way to Franklin Road at Caldwell open house

As part of Governor Little’s Leading Idaho initiative, the Idaho Transportation Department (ITD) is hosting an open house to share design plans for the future widening of Interstate 84 between the Centennial Way and Franklin Road interchanges in Caldwell. All community members are invited to participate in-person or online starting Wednesday, Nov. 9.

The in-person meeting will be held Nov. 9 at the Caldwell Elks Lodge, 1015 N. Kimball Avenue, from 5 – 7 p.m. Attendees will have the opportunity to review ITD’s design plans, ask questions to the project team, and provide their input. All meeting materials will also be available online at itdprojects.org/i-84-centennial-way-to-franklin-ic, with comments accepted through Nov. 16.

“We are continuing to widen I-84 through Canyon County to reduce congestion and increase safety,” said ITD Project Manager Mark Campbell. “Throughout the process, ITD is committed to engaging with travelers who use this portion of the interstate and we are excited to get this project done together.”

 

 

 

Proposed improvements include:

  • Widening I-84 to three lanes in each direction
  • Adding auxiliary lanes between interchanges
  • Replacing the 10th Avenue Interchange
  • Adding a traffic signal to the Centennial Way Interchange westbound off-ramp
  • Building a sound wall along Hannibal Street
  • Rehabilitating the pedestrian bridge over I-84

Design work on this section of I-84 began in late 2021 and construction is anticipated to begin in summer 2023.

The I-84 corridor projects are expected to improve safety, mobility and economic opportunities in Idaho over the next 20 years. More information is available at itdprojects.org/84corridor.

This project is funded with Transportation Expansion and Congestion Mitigation (TECM) funds as part of the Leading Idaho initiative. The program allows ITD to accelerate project timelines to address rapid growth and build critical infrastructure today that would otherwise take many years to fund and build.

In cooperation with the City of Payette and Payette County Road and Bridge, crews will repave the driving surface of the bridge on Thursday. The bridge will be closed to travelers starting at 8:00 a.m. and will reopen when work is complete later that evening, by approximately 8:00 p.m. Please check Idaho 511 at 511.idaho.gov for the most up-to-date information.

Design work is currently underway on plans for a future bridge replacement scheduled for construction in 2026.


ITD and the Idaho State Police advise motorists to slow down and pay attention when driving in work zones, where increased speeding fines and other penalties apply. Motorists are encouraged to plan ahead and visit 511.idaho.gov for information on the state highway or interstate system.

Construction activity picks up on U.S. Highway 20/26 widening

Construction activity is picking up along U.S. Highway 20/26, as the Idaho Transportation Department’s planned improvements to widen the Chinden West corridor continue. This work is part of ITD’s efforts to reduce congestion and crashes on this heavily traveled corridor.


I-84 to Middleton Road

Starting the week of September 12, construction will begin mostly off the highway on the southside of this section of US-20/26. Work includes utility and irrigation construction during daytime hours. As construction progresses, lane reductions are planned, but will be announced well ahead of time. Construction in this section is anticipated to be complete in 2024.

Middleton Road to Star Road

Preliminary design continues on this 6-mile segment of US-20/26. ITD will share updates and host another open house in 2023 for the public to view final design plans. A link to materials shared during the previous May 2022 open house is available at itdprojects.org/chindenwest.

Star Road to State Highway 16

Drivers should currently plan for overnight lane closures on this portion of US-20/26 starting the week of October 10. The highway will be reduced to one lane in each direction with intermittent delays of up to 15 minutes between the hours of 10 p.m. and 5 a.m. Traffic on Star Road near the highway will also be limited. Flaggers will guide drivers through the work zone. Lane reductions will occur throughout construction as ITD works to widen the highway over the next two years.

Meridian Road to Locust Grove Road

Beginning the week of September 26, crews will start utility work and clearing the ITD right of way in order to widen this section of US-20/26 to two lanes in each direction. This work will continue through December, then paving and road reconstruction is anticipated to start in February 2023 or when temperatures allow. All work will wrap up in early summer.

During construction, one lane in each direction will remain open through the work zone. However, motorists can expect shoulder work, reduced speeds, and periodic lane closures with occasional night work. Specific updates regarding schedule and potential traffic impacts will be provided to residents and businesses in the area when available.


For all work along US-20/26, ITD reminds drivers to slow down, watch for posted signs, and sign up for construction updates by either emailing chindenwest@itd.idaho.gov, calling 208.334.8007, or visiting itdprojects.org/chindenwest.

Work begins to repave State Highway 55 in Valley County

Monday, September 12, the Idaho Transportation Department (ITD) begins work to repave State Highway 55 between Round Valley Road and Clear Creek in Valley County.

The project will focus on repaving a six-mile stretch of highway south of Cascade, repairing cracks, potholes, and overall uneven surfaces caused by weather, usage, and age. Additionally, construction will level out steep approaches and add a pavement apron to all roads and driveways connecting to the highway, providing a smooth and safe transition onto the newly paved surface.

Travelers should expect delays of up to 20 minutes while crews work Monday through Friday, although wait times may vary depending on traffic density. Temporary traffic signals will allow one lane to drive through the work zone at a time. Both lanes of SH-55 will be open during the weekend. Weather permitting, the project is expected to finish in late October.

“SH-55 is one of the most iconic highways in the state, with some of the best recreational opportunities Idaho has to offer,” said Greer Gardner, project engineer. “The winter snow this area is so popular for can cause wear on a highway. This maintenance will help improve safety and driving comfort for both Valley County residents and travelers.”
