Construction of innovative intersection redesign at Eagle Rd. and Idaho Highway 44 (ID-44) begins next week

graphic of half CFI

The Idaho Transportation Department will begin construction of a half continuous flow intersection (CFI) at Eagle Road and ID-44 in Eagle on Monday, February 22 to improve mobility and safety at this busy intersection

Connecting two major highways in the Treasure Valley, more than 70,000 vehicles travel through this intersection every day. The half CFI design improves safety and reduces congestion all within relatively small footprint.

Across the nation, CFIs have a proven track record of increased efficiency and safety. This will be the first CFI constructed in Idaho. ITD encourages the public to learn how to navigate through the intersection by watching and sharing an explainer video below.

“The new design does require drivers to pay attention and think ahead, especially on Idaho Highway 44,” said Tyler Coy, ITD Project Manager. “I encourage everyone to learn more about how it works by watching the video during and after construction. When we’re done, there will be overhead signs guiding traffic to the right place. It’s really important people drive attentively.”

Due to traffic volume during the day, most construction will occur overnight between 10 p.m. and 6 a.m. Some work is scheduled during daytime hours but will mostly occur in the roadway shoulders. Nearby businesses and residents may experience loud noise from construction equipment, vibration, and bright light from the work zone.

Motorists are encouraged to slow down and pay attention when traveling in the work zone.

Construction is expected to be complete in early fall 2021.

The total project budget is $8.9M. Knife River is the contractor for construction.

ITD crews make emergency repairs to ID-45 as large number of potholes form

Four men on highway with jackhammers

Idaho Transportation Department crews are completing emergency repairs to a section of Idaho Highway 45 after numerous potholes formed on the roadway.

Potholes continue to form between Deer Flat Road and Melba Road, an eight-mile stretch of ID-45. The damage is caused by water seeping under the surface, freezing – which pushes the pavement up – and thawing, leaving a void.

The voided pavement then collapses under the weight of traffic.

The emergency repairs involve removing asphalt and debris from the hole, cutting out the damaged pavement, and filling the hole with an asphalt material designed for use during cold temperatures. Crews will close one lane of ID-45, controlling traffic with flaggers. Motorists should drive engaged and anticipate delays of no more than 15 minutes. Repair work is expected to take up to two or three days.

“We’ve been patching this section of highway to keep it together,” said Camilo Serrano, the ITD Maintenance Foreman for the area. “With the rain and snow we got, and temperatures dropping then warming up again, we’re seeing a lot of potholes forming. I’m hoping these patches will stick through the winter until we can come back in the spring with better repairs.”

This cold patch material is not as strong as typical asphalt and will only work for a short time. Normal asphalt is unavailable currently as no nearby asphalt mixing plant is operational this time of year due to seasonal conditions. ITD is developing a plan to complete longer-lasting repairs in the spring. The fix will be similar to the operation in 2017 to repair I-84 after many potholes formed during that year’s severe winter.

The Department has previously budgeted for major rehabilitation of the pavement from the Junction of ID-78 to Deer Flat Road, scheduled for 2025. The springtime repairs will be designed with the intent to keep the roadway in an acceptable condition until that time.

ID-21 from Grandjean to Banner Summit to close tonight due to avalanche risk

highway sign for avalanche risk

The Idaho Transportation Department will be closing Idaho Highway 21 from Grandjean to Banner Summit tonight due to a high avalanche risk.

A weather system bringing rain and snow is likely to trigger avalanches in this section of highway. The anticipated closure will begin at 6 p.m. on December 20. However, actual weather impacts may require an earlier closure. Motorists needing to use the roadway are advised to make the trip immediately or plan to use alternate routes.

The alternate route between the Treasure Valley and Stanley area is to travel east on I-84, exit in Mountain Home at Exit 95 to U.S. 20, then head north on Idaho Highway 75.

The ITD Avalanche Crew monitors the snowpack along this section of highway in order to forecast the risk of avalanches large enough to reach the roadway. This practice allows the Department to keep the highway open during the winter months with a reasonable confidence of safety for the traveling public. Previously, the Department closed this section of highway after the first avalanches hit the road.

The Avalanche Crew will continue to monitor the snowpack as a snowstorm hits the area and after. The highway will reopen when the snowpack has stabilized and the risk of active avalanches is reduced. Updates on closures and openings will be posted on 511. Future closures will be announced on 511 and ITD’s Twitter account.

There are sixty regular avalanche paths in this 11-mile stretch of ID-21. Avalanches can be triggered without warning. For this reason, there is no parking or stopping within this section of road during the winter.

Below is a gallery of activities the Avalanche Crew performs during the winter.

It’s time to be Idaho Ready for winter driving

As winter weather arrives in Idaho, the Idaho Transportation Department has launched its annual winter safety campaign, “Idaho Ready.”

The campaign aims to help drivers prepare for challenging conditions on the state’s highways, offering tips and resources to stay safe before drivers hit the road. Short videos, blog posts, and photos will be posted weekly to Facebook, Twitter, YouTube, and online at

So, are you Idaho Ready for winter driving? Here are a few tips to help you stay safe on the road.

First, check road conditions before you leave! Visit or download the Idaho 511 app to look at weather reports and cameras across the state.

Be prepared. Keep an emergency kit with food, water, and a blanket in your car.

If roads are wet or icy, slow down and give yourself plenty of stopping room.

Pay attention to the outside temperature. When it’s near freezing, ice can form quickly, and when gaining elevation, wet roads can change to ice in just a few miles. Even when the temperature is above freezing, shaded roadways can be slick. Take it easy on overpasses and bridges too. These are the first to freeze when temperatures drop.

Snow tires and chains can help keep you moving, but be sure to practice installing your chains so you know how to use them.

When roads are slick, turn your cruise control off. If you start to slide, regain control by taking your foot off the gas and slowly turning your wheel in the direction of the skid. Try not to overcorrect, and do not slam on the brakes.

If you encounter a snow plow, slow down and make room. The safest place is behind the plow. Never pass on the right.

Please wear your seatbelt, stay engaged, and drive for the conditions. Be sure to follow along online with ITD this winter so you are always Idaho Ready.

Idaho DMV issues extension on expiring registrations and driver’s licenses

The Idaho Transportation Department’s Division of Motor Vehicles is providing an extension on expiring vehicle registrations and driver’s licenses. In an effort to reduce wait times at county DMV offices, non-commercial vehicle registrations and driver’s licenses that expire between September and December 2020, now have until January 31, 2021 to renew.

In mid-October ITD implemented the fourth and largest phase of the state’s DMV modernization project, moving the vehicle registration and titling system from a 1980s mainframe to an updated computer program. Eight million records were integrated into a “one person, one record” system, linking each Idahoan’s registration and title information with their license.

The new system has temporarily slowed vehicle registration and title processing, and ITD is working diligently to speed up transaction times. COVID-19 social distancing measures with limited hours and appointment times also contribute to a backlog in service. The extensions will allow customers more time to safely complete their business. ITD is doing everything possible to reduce wait times, especially as temperatures drop this fall and winter.

“People with expiring registrations and licenses don’t need to rush to the DMV. These extensions should give them some relief, help reduce crowd sizes, and also open up appointment windows where available at county offices,” said DMV Administrator Alberto Gonzalez. “We also encourage Idahoans to renew their registration online, by mail, or drop boxes at county offices.”

DMV online services, including driver’s license and registration renewal, are available 24/7 at Please note, county DMV office hours are determined by county sheriffs and assessors, and vary statewide. Hours and contact information can be found at

Idaho DMV update on vehicle registration and titling system

The Idaho Division of Motor Vehicles team is working all hours to refine the state’s new vehicle registration and titling computer system. Customers at county DMV offices are currently experiencing extended wait times. Please remember, many DMV services are available ONLINE at We encourage you to skip the line and renew online 24/7.

In an effort to reduce wait times, the Idaho Transportation Department is providing an extension on expiring vehicle registrations and driver’s licenses. Non-commercial vehicle registrations and driver’s licenses that expire between September and December 2020 now have until January 31, 2021 to renew.

During the Columbus Day weekend (Oct. 10-12), the Idaho DMV transitioned the state’s vehicle registration and titling system from a 1980s mainframe to the new GEM system. Eight million DMV records were integrated into a “one person, one record” system. This means each Idaho driver will have one record with both their driver’s license and vehicle registration/title information linked.

“We apologize for any longer than normal wait times at your county DMV office,” said DMV Administrator Alberto Gonzalez. “Upgrading from a 40-year-old computer system is a big project, and merging millions of records is a challenging process. The GEM system is not yet perfect, as we continue to clean years of data, but it is improving every day.”

The Idaho DMV asks customers to please have patience with county staff until the system is operating more smoothly. For more information and resources visit

Reminder: Drive Insured! Insure your vehicle or lose your registration

Drive Insured! Be safe, be smart! Insure your vehicle or lose your registration.

A reminder to Idaho vehicle owners, drive insured or lose your registration.

Under Idaho law, vehicle owners without insurance coverage for two consecutive months risk having their registration suspended by the Idaho Division of Motor Vehicles.

The Drive Insured law (Idaho Code 49-1234) was passed during the 2019 Idaho legislative session, and went into effect in January 2020. As part of the DMV’s efforts to help Idahoans through the unprecedented COVID-19 emergency, implementation was initially delayed.

The DMV receives data from licensed Idaho insurance companies identifying vehicles with coverage. Owners without coverage for two consecutive months will receive a warning letter, then have 30 days to provide proof of insurance or obtain an exemption before their registration is suspended.

To reinstate a suspended registration, owners will need to provide proof of insurance and pay a fee of $75.

Impacted drivers should expect warning letters in the mail this October, though at any time, the DMV encourages Idahoans to use the Drive Insured self-reporting tool at This tool allows drivers to verify the DMV has a record of their insurance, report a change in their insurance situation, or file an exemption. While insurance companies are required by law to provide this data, some fail to do so and it may result in a vehicle incorrectly identified as not having insurance. Using the self-reporting tool is a simple step that can give drivers peace of mind if they are concerned the DMV is not up to date on their current situation.

Please note, county DMV offices are not involved with Drive Insured, and affected vehicle owners cannot report their insurance in-person there. Please use the Idaho DMV’s online self-reporting tool, or call 208.334.8075.

Some vehicles are exempt from this statute. The law applies only to non-commercial vehicles, and excludes trailers and off-highway vehicles. For a full list of frequently asked questions, visit and click the Drive Insured heading.

Report shows significant reduction in human-caused fires along I-84 even as traffic increases

BLM crews conduct a prescribed burn along ID-51

As historic catastrophic wildfires ravage the coastal states, a new report from the Bureau of Land Management is showing positive results of a fuel reduction program along Interstate 84 in southwest Idaho, a partnership between BLM and the Idaho Transportation Department.

The fuel reduction program began in 2013. Since that time, fires along the interstate have decreased in size by 95%. During that same time, the amount of traffic has increased by 30%. You can read the report on BLM’s website here.

The program involved BLM identifying critical areas for vegetation growth alongside I-84 between Boise and Mountain Home. Working with ITD maintenance crews, these areas are treated with various methods. In some locations, additional gravel is placed beside the shoulder to lengthen the distance between fuels and potential fire starts from vehicles. ITD maintenance crews will mow alongside highways to reduce available fuel. In some instances, BLM crews will conduct controlled burns to eliminate built-up vegetation. The video below captures this work.

“The partnership with BLM has been very good for the traveling public,” said Carl Vaughn, ITD foreman out of Mountain Home. “We’ve seen few fires along I-84, which means fewer road closures. We’ve knocked down barriers between the federal agency and our own to the benefit of the people we’re here to serve.”

You can do your part to prevent human caused wildfires along the roadway. Before you leave on your next trip, check beneath your vehicle and make sure nothing is dragging close to the ground. If towing, ensure safety chains are not dragging. Don’t park your vehicle in tall or dry grass, where contact with a hot part can cause a fire start. For more safety tips, visit

Blasting and road closures begin on ID-55 Smiths Ferry project

The Idaho Transportation Department (ITD) starts the blasting portion of the Idaho Highway 55 Smiths Ferry project Monday, September 21.

Drivers can anticipate the fall road closure schedule of Monday through Thursday, 10 a.m. to 2 p.m. to begin Monday. If motorists need to travel during this time frame, they are encouraged to plan around this schedule or use US-95. These closures will continue through mid-November when construction will pause for the winter months.

Crews will work during the closures to safely blast and remove rock from the canyon to widen the roadway between Smiths Ferry and the Rainbow Bridge. Large equipment, including steel containers and temporary barrier to prevent falling rock from entering the travel lane, and protect the crews working next to traffic in the narrow work zone, will fill one lane. As a result, drivers can expect one-way, alternating traffic when blasts are not being conducted. Motorists can find additional details on ITD’s project website.

“For the safety of our crews and travelers, please plan for the road to be closed every Monday through Thursday from 10 a.m. to 2 p.m. until this winter when construction will pause,” Vince Trimboli, ITD Communications Manager said. “We appreciate the public’s patience during the project as we make these much needed safety improvements.”

As a reminder, seasonal closures and traffic patterns will be as follows:

  • Fall (September – November): One-way alternating traffic; daytime and nighttime work, seven days a week; full road closures Monday – Thursday from 10 a.m. – 2 p.m.
  • Winter (December – Mid-March): No construction expected; all lanes open
  • Spring (Mid-March – Mid-May): One-way alternating traffic; daytime and nighttime work, seven days a week; full road closures Monday – Thursday from 10 a.m. – 2 p.m.
  • Summer (Mid-May – August): One-way alternating traffic; daytime and nighttime work, Monday – Friday

The project is expected to be completed by late fall 2022. Motorists are encouraged to sign up for text and email alerts to get the most up-to-date information on the project.

In the event of an emergency, ITD and emergency service providers have a system in place to allow vehicles through the work zone so they can transport patients or respond to other emergencies in a safe, timely manner.

Additional lanes on ChindenWest Corridor complete from Idaho 16 to Linder Road, work to the east progresses

ChindenWest looking west with completed roadway

The Idaho Transportation Department has opened four lanes of Chinden Boulevard from Idaho Highway 16 to Linder Road to traffic, marking a major milestone in the ChindenWest Corridor project.

The widening of this section of Chinden Boulevard from two lanes to four began this spring. It will ensure the safety and mobility of the traveling public ahead of new development in the area. The new roadway includes four 12-foot travel lanes, two in each direction, and a detached 10-foot pathway to the south for bicyclists and pedestrians.

“Credit for this project’s success goes to the great partnership of everyone involved,” said Jayme Coonce, Engineering Manager for ITD District 3. “To reach this milestone, we needed the hard work and support from the City of Meridian, the developer, the Ada County Highway District, and our contractor, Idaho Materials and Construction.”

As this three mile section reopens to typical highway conditions, Locust Grove to Eagle Road prepares for a significant traffic shift, beginning Sept. 21, that will eliminate one through lane, both east and westbound, at the Eagle intersection (see graphic below).

Graphic of new traffic patter from Locust Grove to Eagle Road

“At the east end of the ChindenWest corridor, paving operations will be occurring between Locust Grove and Eagle Road,” said Michael Lucas, ITD’s project manager for this section. “The necessary lane shift may result in increased congestion during peak drive times. We encourage motorists to consider alternate routes when possible and appreciate everyone’s patience.”

The two-mile segment between Linder Road and Locust Grove Road is underway with the most significant construction activities scheduled for 2021.

The ChindenWest Corridor is a vital east-west connection in the heart of the Treasure Valley. The construction will add travel lanes, widen shoulders, and build a separated path parallel to the roadway.

The project website,, serves as a hub of information for the public, including videos that provide a window into the future. The one-stop-shop website includes detailed information about construction activities, anticipated traffic impacts, and the improvement designs.
