Repaving work begins Monday, June 27 on State Highway 45 between Walters Ferry and Nampa

The Idaho Transportation Department (ITD) is making improvements to State Highway 45 between the State Highway 78 junction in Walters Ferry and Deer Flat Road in Nampa. Construction on the 13-mile stretch of road will begin Monday, June 27. All work is expected to be complete by early September.

Construction plans include replacing the bridge deck at Mora Canal, resurfacing the pavement between the SH-78 junction in Walters Ferry and Deer Flat Road in Nampa, and widening the turning radius on SH-45 at Missouri Avenue and at Patterson Avenue. This project will extend the life of SH-45.

Motorists should expect the following traffic impacts this summer:

  • Work will take place during the day and night.
  • One lane of SH-45 will be open with flaggers directing traffic. Please plan for delays up to 15 minutes.
  • The speed limit will be reduced.
  • Drivers can expect an uneven road surface and bumps when entering SH-45.
  • Access to and from homes and businesses may be closed for up to one hour. ITD will notify those affected prior to closures.

Work will temporarily pause over the Independence Day holiday weekend. For more information about the project visit

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 for information on the state highway or interstate system.

Sealcoating to begin next week in Lincoln, Jerome, Twin Falls and Gooding counties

Weather permitting, on Monday (June 27) the Idaho Transportation Department will begin sealcoating multiple portions of roadway throughout the region to preserve the pavement.

“Throughout the next month, we will sealcoat approximately 82 miles of highway,” said ITD Engineering Manager Travis Hitchcock. “The sealcoat will both protect the surface of the roadway and provide better traction for drivers.”

Work will occur on five highways in the South-central Idaho region:

  • State Highway 24 (milepost 32 – 68)
    • State Highway 25 (milepost 5 – 18)
    • State Highway 46 (milepost 111 – 130)
    • State Highway 50 (milepost 5 – 8)
    • U.S. Highway 26 (milepost 139 – 150)

While work is underway, roadways will be reduced to a single lane. Both lanes will be open to traffic outside of working hours.

Motorists should anticipate short delays and watch for the presence of flaggers and pilot cars during the day.

Sealcoating is a surface treatment that takes place during the summer months and involves applying a layer of oil and rock chips to the roadway. The process requires hot temperatures and dry weather for chips to properly adhere to the oil.

Chips placed during sealcoats have the potential to cause windshield damage so drivers are cautioned to slow down and pay attention to reduced speeds and no-passing zones throughout the work area.

Geneva Rock Products Inc. is the primary contractor on this project which is expected to be complete by the end of July.

Motorists are encouraged to plan ahead for temporary daytime lane reductions on Blue Lakes Boulevard this week as part of the continuing pavement rehabilitation project in Twin Falls.

The Idaho Transportation Department (ITD) and its contractor, Idaho Materials & Construction, will be working 24 hour shifts to safely reopen all lanes of traffic from the Perrine Bridge to Pole Line Road. Unforeseen issues with stormwater drainage in the construction zone are requiring temporary daytime closures.

“Safety is our top priority, and ITD is working closely with IMC to reopen lanes during the day, and continue work during overnight hours as planned,” said ITD Resident Engineer Seth Helms. “ITD appreciates commuters for their patience during this important work.”

State Highway 55 and Banks-Lowman Road summer flagging schedule

As summer travel increases to Idaho’s mountain destinations, ITD’s Southwest Idaho office will also increase flagging resources at the busy State Highway 55 and Banks-Lowman Road intersection in Banks. ITD will flag traffic on the eight weekends expected to have the highest number of travelers due to local events and holidays. These weekends were selected in cooperation with a community working group involving Boise and Valley County community members.

  • Sunday, June 19
  • Independence Day, Monday, July 4
  • All remaining Sundays in July: 10, 17, 24, and 31
  • Sunday, August 7
  • Labor Day, Monday, September 5

Plan ahead for any road trip by checking for the latest road conditions, and for road construction work happening across the state. ITD asks drivers to please do your part to keep roads safe and prevent crashes. Slow down, drive engaged, and always buckle up.

Work begins later this month on SH-21 in Custer County

Construction is expected to begin June 27 on State Highway 21 northwest of Stanley. In the coming weeks, crews will replace an old culvert at Elk Creek (milepost 123.06) with a new bridge.

“The current culvert was placed in 1966 and has exceeded its life expectancy,” ITD Designer Andrew Young said. “The new structure will be both wider and longer and will serve motorists for decades to come.”

The new bridge also aims to improve fish habitat in the area.

“When we build the new structure, we will be providing a better natural channel that will be more favorable to fish,” stated Young. “We will also have temporary fish passage in place during construction.”

While construction is underway, traffic will be reduced to a single lane. Temporary traffic signals will be in place to direct motorists through the work zone. Drivers should anticipate delays up to 15 minutes when traveling through the area.

Braun Jensen is the primary contractor on this project that is expected to be complete this fall.

New study taking broader look at Huetter Bypass, traffic flow in CDA area

Development encroaches on Huetter Road and surrounding farmland

A new study is now underway to take a broader look at the Huetter Bypass and traffic flow in the Coeur d’Alene metro area.

“With the rapid growth in the area causing a huge increase in traffic, our existing routes are experiencing low levels of service, and drivers don’t have quick ways to get around,” said Joey Sprague, who will manage the study for the Idaho Transportation Department (ITD). “With this study we’ll look at the way the local and state routes in the area work as a system, and that starts by evaluating the work that’s already been done so that we can chart a path forward.”

The first phase of the study will review work previously done by the Kootenai Metropolitan Planning Organization on the idea to expand Huetter Road to serve as another north-south freeway connecting I-90 and U.S. Highway 95 north of Hayden.

The study is expected to encompass a larger area between I-90, US-95, State Highway 53 and State Highway 41 to identify the pain points and how to address them given growth in the area. Solutions may include a range of options, like modifying existing routes or building new ones.

“Right now it’s about understanding regional traffic and how it interplays with the original Huetter corridor study, especially since some studies are dated,” Sprague said. “For this first phase of the study, we’re just gathering data. In future phases of the study, we’ll let the data point to options including and beyond the bypass, and once we have vetted some of those ideas, we’ll ask the public to weigh in.”

ITD officially took over planning for the bypass in October and is managing the latest study being conducted by HDR, Inc.

“It took more time than expected to determine the scope of the study and hire a company to do the work, but the study will now officially kick off this month,” Sprague said. “We expect to have more information available on it later this summer.”

Construction to begin in July at Ashton

Ashton Intersection

ASHTON – Beginning July 6 the Idaho Transportation Department will commence work on two projects at Ashton. The first project, at the intersection of US-20 and SH-47 in Ashton, will consist of extensive work to improve safety and traffic flow. The second project will be a pavement overlay along SH-47 beginning near North Fremont High School and continuing to Bear Gulch.

The US-20 / SH-47 intersection project will consist of a stoplight, new curb and sidewalks, storm sewer work, and pavement. Work is scheduled to be completed in October. Traffic patterns will change periodically to allow for construction.

A public meeting will be held on Wednesday June 29, 2022 at 11:00 a.m. at the Ashton City hall for those that wish to discuss construction plans at the intersection and express concerns.

The paving project on SH-47 east of Ashton will last for approximately 15 days. Crews will be microsurfacing the roadway to improve and protect the road surface. During work there will be single lane closures and pilot cars to control traffic flow.

Motorists are asked to watch for workers and equipment, follow all traffic signs and flaggers, and reduce speeds to posted limits. Traffic control and safety devices will be changing often to accommodate construction activities.

Citizens with questions regarding the US-20 / SH-47 intersection can contact HK Contractors at (208) 523-6600.

I-84 expansion will require extended ramp closures at Franklin Road Interchange in Caldwell this summer

The Idaho Transportation Department (ITD) is nearing a major milestone in the Interstate 84 widening project in Caldwell, bringing extended ramp closures and traffic changes near the Franklin Road Interchange (Exit 29).

Between June and September, each of the ramps at the Franklin Road Interchange will close for six weeks. The closures will allow crews to rebuild the ramps and connect them to new lanes on I-84.

Although exact dates are subject to change due to weather and other factors, ITD expects:

  • On June 19, the westbound off-ramp will close at 10 p.m. and remain closed for six weeks. Drivers will be detoured to 10th Avenue, where they can turn around and access Franklin Road from eastbound I-84.
  • On June 26, the eastbound on-ramp will close at 10 p.m. and remain closed for six weeks. Traffic will detour down 21st Avenue to Blaine Street, then west to the 10th Avenue Interchange.
  • On June 26, Linden Street will close under I-84 at 10 p.m. until late 2022 while crews finish the reconstruction of the underpass.

Once these two ramps re-open in late July, the other two ramps will close until early September. In addition to the extended closures, motorists can expect occasional nighttime lane restrictions on I-84 and ramps in the area. To request email or text updates about upcoming closures, text 84CORRIDOR to 1-866-483-8422.

“We have been working with our engineers and community leaders since 2020 to determine the best way to deliver this complex project while keeping traffic moving,” said Shawna King, ITD Design/Construction Engineer. “We ask motorists to be patient this summer and drive safely. We will keep everyone informed and look for every opportunity to expedite the process.”

ITD is expanding I-84 to three lanes in each direction between the Franklin Road Interchange in Caldwell and the Karcher Interchange in Nampa. Traffic will be shifted to the newest lanes in the I-84 median in June, allowing crews to begin rebuilding the existing outside lanes.

Construction on I-84 in Caldwell will be complete in 2023. For more information, visit, email or call (208) 334-8002.

View of Interstate 84 near Jerome, Idaho.

The Idaho Transportation Department (ITD) is holding an in-person meeting tomorrow (June 14) to share plans for widening Interstate 84 from the South Jerome Interchange to the Twin Falls Interchange. The meeting will be held at Con Paulos Chevrolet in Jerome from 4:30 p.m. to 6:30 p.m.

The meeting will be held in open-house format and provide members of the public an opportunity to review design plans and provide input. If individuals are unable to participate at the in-person meeting, a self-guided online meeting option will be available from June 14 until June 28 at

The interstate serves as a major corridor through South-central Idaho and beyond, with traffic counts expected to double over the next 20 years. The purpose of this project is to increase capacity and improve safety. Once funding has been confirmed, construction may start as early as 2023.

“Widening this section of I-84 will allow us to proactively address capacity and safety needs between Jerome and Twin Falls,” said ITD Engineering Manager Crystal Craig. “We are advancing this project to construction as soon as possible and plan to keep the public involved through each phase.”

This design project is funded with Transportation Expansion and Congestion Mitigation (TECM) funds as part of Governor Little’s “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. Construction funding will be identified at the time that the project is ready to advertise for construction bids.

US-95 south of Lapwai reopened following repairs to flood damage

Fresh pavement on US-95 near Lapwai

June 15 update

Both lanes of U.S. Highway 95 south of Lapwai at milepost 296 are now open following repairs to damage caused by flooding earlier this week.

Floodwaters from Lapwai Creek first began eroding the northbound lane on Monday morning, and the Idaho Transportation Department reduced traffic to one lane. Repairs began later that day, with crews bringing in rock to replace what was lost and prevent further damage.

“We are happy to return US-95 to normal condition,” Operations Engineer Jared Hopkins said.

One lane of U.S. Highway 95 remains closed south of Lapwai at milepost 296 due to flood damage.

“With floodwaters receding and drier days in the forecast, we feel we are past the emergency,” Operations Engineer Jared Hopkins said. “Yesterday, we rushed to get an excavator on scene to start placing large boulders against the bank to save what remained of the northbound lane of US-95. In one spot, it had washed away to the center.”

Watch a video of the flooded creek.

Watch a video of traffic moving around the damaged section.

Crews aim to finish placing rock and reopen both lanes of the highway by the end of the week.

“We are working hard to have two lanes open with an asphalt surface as soon as we can,” Hopkins said. “Then we’ll start focusing on more permanent repairs later this summer.”

Water over the roadway has also been reported on State Highway 6 between Potlatch and Deary. Before traveling drivers should check conditions on their routes at

Earlier this morning, the Idaho Transportation Department closed one lane of U.S. Highway 95 four miles south of Lapwai at milepost 296 due to flooding.

“Flooding of Lapwai Creek has washed away the shoulder next to the northbound lane and may be undermining the highway,” Operations Engineer Jared Hopkins said. “Closing that portion of the roadway is necessary to ensure safety.”

More rain is expected today and tonight.

“Until the rain stops and the creek drops, there’s nothing we can do except monitor the flooding and close the highway if necessary,” Hopkins said. “We want to put drivers on notice that we may need to shut it down.”
