US-95/12 Aht’Wy Interchange in First Construction Phase

The Aht’Wy Interchange project on US-95/12 which is near the Clearwater River Casino & Lodge RV Park is currently in its earliest construction stages. After a well-attended groundbreaking ceremony this past April, contractors are getting started and motorists can expect some changes in traffic patterns.

The initial stage will consist of work in the median area to construct crossovers to facilitate traffic needed for future stages. Once this work is complete, the contractor will make changes to the traffic patterns and reconstruct the northbound lanes. During these initial stages, travelers can expect single lanes in each direction. Please drive safe and be mindful of construction workers and equipment working close to the roadway.

The new diamond-shaped interchange will replace current at-grade intersection with an overpass to access the plaza, on the east entrance. This includes additions of deceleration and acceleration ramps for eastbound traffic. As for additional infrastructure, a broadband conduit and pedestrian walkway will be included in the construction.

Deadly crashes go up during summer months

WHAT: Wrecked vehicle on display to raise awareness about the 100 deadliest days
WHO: Boise Police Chief Ron Winegar, Boise Police Cpl. Kyle Wills, Caldwell Police officer Tom DeFur, ITD, AAA
WHEN: Friday, May 19th, 2023 at 1:00 p.m.
WHERE: Boise Towne Square Mall, 350 N Milwaukee St, Boise, ID 83704, Media please use the main entrance

BOISE– Every year during the months of June, July, and August there is an increase in the number of car crashes that unfortunately result in death or injury. These months are known as the “100 deadliest days” and Boise Police, Caldwell Police, the Idaho Transportation Department, AAA and the Boise Towne Square Mall are teaming up to remind drivers to stay safe this summer.

On Friday, May 19th, these agencies will use a wrecked vehicle from an aggressive driving crash on display at the Boise Towne Square Mall as a reminder to slow down, limit distractions and focus on driving.

“With so many options available to distract us when we’re driving, we hope that this display of a wrecked vehicle will give drivers the motivation to put down the distractions and just drive the speed limit,“ said Boise Police Cpl. Kyle Wills.

According to the Idaho Transportation Department (ITD), there were 72 fatal crashes across Idaho last summer between Memorial Day and Labor Day. So far this year, 71* people have died on Idaho roads. Six* of those fatalities happened in the last week alone. The year-to-date total from the same time last year was 52 fatalities.

“That’s 71 tragedies for families, friends and communities across Idaho,” said Josephine Middleton, Highway Safety Program Manager with ITD. “As we head into the 100 Deadliest Days and the rest of the year let’s focus on protecting each other on the roads by stopping the behaviors that contribute to traffic crashes.”

ITD data shows that 15% of all fatal crashes are distracted-driving related. Distracted driving is any activity that diverts attention from driving, including talking or texting on your phone, eating and drinking, talking to people in your vehicle, fiddling with the stereo, entertainment or navigation system—anything that takes your attention away from the task of safe driving.

Speed is also a significant factor in many crashes. Speeding, which includes exceeding the posted speed limit or driving too fast for conditions is considered aggressive driving. According to ITD, 35% of all fatal crashes are aggressive-driver related. Other aggressive driving behaviors include following too closely, weaving, and failure to yield or stop at a sign or signal.

“Safe driving is also sober driving, and you can’t drive anywhere safely if you’re impaired. With 37% of all fatal crashes involving an impaired driver, we urge you to get a designated driver or use ride-sharing services if you plan to drink” said Wills.

It’s illegal everywhere in America to drive under the influence of alcohol, marijuana, opioids, methamphetamines, or any potentially impairing drug–prescribed or over the counter.

At Friday’s media event, Caldwell Police officer Tom Defur will share his own personal story to remind drivers about the importance of safe driving.

Safety project starts Monday on US-95 near McArthur Lake

On Monday, May 22, construction will start on U.S. Highway 95 near McArthur Lake to reconstruct the highway and adjust sharp curves.

Plans call for one mile of US-95 to be realigned to soften curves and for the small box culvert to be replaced with a longer bridge. The south end of the bridge will be shifted to the east approximately 50 feet, and crews will remove dirt and other material from underneath the bridge to provide better clearance for wildlife passage.

Additionally, more than one-half mile on each side of the highway will be fenced to help funnel wildlife to the bridge for a safe crossing within the project limits.

“In this half-mile stretch of highway, 51 wildlife mortalities have been documented in the past decade, with many more going unreported,” said Norm Merz, the Regional Wildlife Habitat Manager with the Idaho Department of Fish and Game. “The replacement of the box culvert with a bridge and funnel fencing will allow wildlife to access habitat on both sides of the highway while reducing the risk of auto-wildlife collisions.”

Safety improvements will take two years to complete. For the first month, flaggers will intermittently stop traffic on US-95 as crews remove the part of the existing highway. The contractor will also begin building a temporary two-lane road around the work zone to allow traffic to flow smoothly until construction is finished in the fall of 2024.

Drivers should check 511.idaho.gov before traveling to plan ahead for any delays from work zones.

Tom Mahoney takes reins as new Idaho Aeronautics Administrator

BOISE – Tom Mahoney, an Idaho pilot with more than three decades of aviation experience in the Gem State, takes over May 15 as the new Idaho Division of Aeronautics Administrator. He replaces Jeff Marker, who is retiring in early June after nine years with the department and four years as Aero’s Administrator.

In leaving, Marker stated he is incredibly honored to have had the opportunity to work for ITD

“This is an extraordinarily professional group, and I feel privileged to have been at least a small part of the team,” Marker explained. “Aero and ITD will be in great hands as Tom takes over as Administrator.”

Mahoney brings enthusiasm and a wealth of Idaho experience to the new position.

“I am thrilled to be selected,” Mahoney said. “I am glad to continue to contribute to air commerce and safety in Idaho, a state that benefits tremendously from aviation.”

Mahoney has been a military aviator, aircraft owner, small-business owner, flight instructor, and air charter pilot in Idaho for the past 30 years.

“I will use all of those skills as I serve the team members in the Aeronautics Division,” he added. “I look forward to continuing Jeff Marker’s legacy and supporting the vision and mission of the Idaho Transportation Department.”

Aviation runs in Mahoney’s blood. “Aviation has been a passion of mine since winning an art contest for United Airlines when I was eight years old,” he said. “My father was a United Airlines employee, so I had early exposure to many great people in aviation.”

Like Marker, Mahoney has an Air Force background. He is a graduate of the U.S. Air Force Academy (Physics), Air Force Test Pilot School, Master of Aeronautical Science from Embry-Riddle University, and an MBA from the Wharton School at the University of Pennsylvania. After a decade of flying fighter aircraft, Tom served for four years as a budget officer in the Pentagon.
