Cultural discoveries on a highway construction project in northern Idaho that changes the narrative for Native American heritage in the area, and the state’s first wildlife overpass, were the catalysts for a pair of awards Oct. 31 from the nation’s premiere transportation governing body.

The awards were presented to the Idaho Transportation Department (ITD) at the annual meeting Thursday of the American Association of State Highway and Transportation Officials (AASHTO) in Philadelphia, Pennsylvania.

“These two AASHTO national awards again prove that our employees are fantastic,” confirmed ITD Chief Deputy and Chief Operations Officer Dan McElhinney. “The SH-21 Lucky Peak wildlife crossing is a great partnering example, and the U.S. 95 McArthur Lake Bridge showcased excellent Tribal teamwork. Partnerships solved wildlife safety with cultural preservation success.”

The cultural award was received by Jyl Wheaton of the Kootenai Tribe of Idaho (KTOI) and ITD Project Manager on the construction, CarrieAnn Hewitt.

The project itself was fairly straightforward – an $11M project in Boundary County that rebuilt an existing two-lane section, adding wider shoulders, and replacing a box culvert over Deep Creek, which provides an outlet to McArthur Lake. The existing width-restricted box culvert was replaced with a 300-foot span bridge to provide safe animal passage under the highway. During excavation, tribal artifacts were found, requiring an orchestrated approach to planning for the preservation of these key cultural resources. A one-of-a-kind partnership was forged between ITD, the Kootenai Tribe of Idaho, and contractors to preserve the rich history of the area’s indigenous people. One of the discoveries was a game-changer in terms of traditional thought. Native American artifacts were found that pre-dated the earliest-known timelines – these artifacts showed that the earliest human existence in the upper Columbia River Basin came some 4,000 years earlier than previously thought!

ITD’s Scott Rudel managed the wildlife overpass project, built on State Highway 21 just east of Boise. The $7.5M project constructed a 150-foot long wildlife overpass and more than a mile of big-game fencing parallel to the highway to guide animals to the overpass, significantly reducing wildlife-vehicle collisions on this busy highway section. Improving motorist safety and protecting the well-being of residents and commuters, along with wildlife alike benefits the traveling public, hunting and recreational heritage, and helps sustain the benefits our valuable wildlife resources and public lands provide. ITD wildlife-vehicle crash safety data and Dept. of Fish and Game GPS data determined the location of the overpass by finding where most migrating mule deer and elk crossed the highway. This is the next step in the long-range vision to promote safety, mobility, and economic opportunity along SH-21 between Lucky Peak and Idaho City. The goal is to reduce wildlife collisions in the area by 80%.

The AASHTO President’s Transportation Awards are considered the highest honor for state departments of transportation. It is proof positive that ITD consistently produces great projects on behalf of the taxpayers of Idaho. The two awards mark 23 President’s Awards received since 2014.

The Idaho Transportation Department’s avalanche team is back in Lowman preparing for the upcoming winter season. The team recently conducted an aerial assessment to evaluate changes in the corridor caused by the Wapiti Fire.

“The aerial survey gave us a clearer understanding of the risks,” ITD Avalanche Team Leader Bill Nicholson said. “We feel reassured as it pertains to avalanches. However, the fire has increased the potential for mudslides and debris flows. Our team is ready, and we remain focused on keeping the highway safe for travelers just like we do every year.”

Another difference this winter brings is La Niña. The National Weather Service predicts colder temperatures and increased precipitation for the region. Excessive moisture in areas impacted by wildfires could result in a heightened risk of flooding and slides.

ITD’s avalanche team is stationed in Lowman, 20 miles from an avalanche-prone section of State Highway 21 that spans from Grandjean to Banner Summit. Every winter, the team monitors conditions and makes the decision on when to close roads due to avalanche danger.

There are more than 70 avalanche paths along SH-21. The ITD avalanche team also closely monitors U.S. Highway 12 near the Montana border.

There are only three highways in the United States that fall under the ‘High’ category in the Avalanche Hazard Index: SH-21 in Lowman, State Highway 210 in Utah, and U.S. Highway 550 in Colorado.

Franklin Road will be closed between McDermott and Star roads in Nampa on Monday and Tuesday. This closure is necessary for crews to safely install overhead sign structures near the future State Highway 16 extension.

The closure will begin at 7 a.m. on Monday and continue until 6 p.m. on Tuesday. Motorists are advised to plan for extra travel time and use an alternate route, as traffic will be detoured to Cherry Lane. Access to businesses and residences in the area will remain open throughout the closure.

Before traveling, drivers are encouraged to check 511.idaho.gov for current road conditions and updates on their route. For more information on the SH-16 project, visit itdprojects.idaho.gov/pages/sh16corridor.

The Idaho Transportation Department will begin striping State Highway 55 today. As crews work their way north, drivers are urged to be patient and avoid passing during active painting operations.

The striping, which will cover the stretch from Horseshoe Bend to New Meadows, is expected to take up to four days to complete.  During this time, a convoy of vehicles consisting of pace cars, a paint truck, and a crash cushion trailer will work together to ensure the safety of both the crew and the public. This line of vehicles will be moving slowly as they paint the roadway markings to ensure they last.

All of Idaho’s highways are painted at least once each year, with some areas receiving a second coat. This year, ITD will stripe more than 3,000 lane miles across Southwest Idaho. Drivers should exercise caution when following striping trucks, as driving over wet paint can strip away the reflective beads, reducing the visibility of road markings at night.

The Snake River Rest Area, located on eastbound Interstate 84, just two miles from Ontario, serves as a vital first stop for many travelers entering Idaho. Unfortunately, the rest area has been the target of repeated vandalism, with three separate incidents occurring in September alone.

The recent acts of vandalism include a shattered window, a broken glass door, and the destruction of a child changing area. This rest stop not only provides essential public restroom facilities but also welcomes visitors to Idaho with its visitor center.

“These facilities are here to serve travelers, but each act of vandalism makes it harder to maintain the level of service we strive to provide. If you see someone acting suspiciously or damaging property, please speak up,” Facilities Operations Manager John Hall said.

The Idaho Transportation Department urges anyone who witnesses vandalism to contact the Payette County Sheriff’s Office.

The Idaho Transportation Department advises motorists to plan for nighttime lane closures on Interstate 84 beginning on Sunday between Meridian and Nampa.

Crews are painting permanent striping and installing overhead signs at the future interchange of State Highway 16 and I-84. One direction of I-84 will be closed each night during this work.

Sunday, Sept. 8:

• Eastbound I-84 will be closed between the Garrity Boulevard (Exit 38) and Ten Mile Road (Exit 42) Interchanges from 9 p.m. Sunday night to 5 a.m. on Monday. Traffic will be detoured down Franklin Road.  Click here for the detour map.

Tuesday, Sept. 10:

• Westbound I-84 will be closed between the Ten Mile Road (Exit 42) and Garrity Boulevard (Exit 38) Interchanges from 10 p.m. Tuesday to 6 a.m. on Wednesday morning. Traffic will be detoured down Franklin Road.  Click here for the detour map.

Additional nighttime lane restrictions on I-84 will continue through September, but at least two lanes will remain open in each direction. The speed limit will be reduced to 45 mph at night.

Update Sept. 12, 2024 – State Highway 21 remains closed as the Wapiti Fire continues to burn between Lowman and Stanley. Despite ongoing fire activity, the Idaho Transportation Department has completed a damage assessment of the area.

Emergency contracts have been established, and repair efforts are actively underway. Crews are currently removing hazard trees along the highway, and assessments indicate that approximately 49 road signs and several miles of guardrail will need to be replaced in Boise County. The guardrail is crucial, given the steep slopes along this mountainous highway.

“We are taking a proactive approach to this situation, and as long as it is safe to do so, we will continue our work in the area. Completing the damage assessment was a critical first step, allowing us to secure the necessary resources and determine what needs to be done to safely reopen the highway when the time comes,” Field Operations Manager Eric Copeland said.

Throughout the duration of this fire, ITD crews will continue to conduct twice-daily patrols using loaders to clear burnt trees, rocks, and debris from the highway, ensuring that fire crews and emergency responders can safely access the affected areas.

To date, the Wapiti Fire has burned more than 120,000 acres and is currently 12% contained. As multiple fires continue to impact Southwest Idaho, ITD encourages travelers to check road conditions at 511.idaho.gov before planning their journeys.

Aug. 20, 2024 – The Wapiti Fire burning in the Boise National Forest has forced the closure of State Highway 21 near Grandjean. Motorists planning to travel between Boise and Stanley will need to take an alternate route through Ketchum on State Highway 75. There is no estimate for when the road will reopen.

The Wapiti Fire is 10% contained and has burned more than 9,000 acres. The Idaho Transportation Department encourages all drivers to check 511.idaho.gov for current conditions on your route.

Here are some additional safety tips for traveling in areas with wildfires:

• Power outages are common near wildfires. Treat non-working traffic signals as four-way stops.
• Bring additional food and water in case your trip is delayed.
• Driving in smoke is similar to driving in heavy fog. Slow down, maintain a steady pace, and stay alert.
• Turn on headlights when driving in smoky areas.
• The safest place to wait for a highway to reopen is at home.  Avoid traveling to closure points to wait, as closures could last for days.

The Idaho Transportation Department (ITD) is hosting two open houses to present alternative concepts as part of the State Highway 44, Interstate 84 to Star Road Project. The alternatives include designs along SH-44 in both downtown Middleton and at the Star Road Intersection.

Details for the open houses are below:

• Tuesday, Sept.10, at Middleton Middle School at 511 W Main Street in Middleton. 4:30 p.m. – 7 p.m. (drop in anytime)
• Wednesday, Sept. 11, at Star Fire Protection District at 11665 W State Street, Ste. B in Star. 4:30 p.m. – 7 p.m. (drop in anytime)

The same information will be available at both in-person open houses and online from Sept. 10-25 at: https://itdprojects.idaho.gov/pages/sh44pel. The project team held four previous open houses in January and April.

“Public feedback and stakeholder input have proven crucial to identifying suitable alternatives so far. Incorporating this feedback with traffic data has narrowed the number of alternatives carried forward. We look forward to sharing these designs and engaging with the public as the project moves to the next step,” ITD Project Manager Mark Wasdahl said.

In this study phase, ITD is implementing the Federal Highway Administration’s Planning and Environmental Linkage process to identify and screen transportation improvements. Once improvements have been chosen, the project will transition into the National Environmental Policy Act phase.
