The Nez Perce Tribal Police, with the support of the Idaho State Police (ISP) and the Idaho Transportation Department (ITD), are urging drivers to follow posted signage and use the Aht’Wy Interchange on U.S. Highway 95 near the Clearwater River Casino and Lodge. Motorists who disregard road closures and traffic signs create dangerous situations that could lead to serious crashes and fatalities.
Since the interchange was opened at the eastern entrance and access at the western entrance was modified, all agencies have observed unsafe behavior. Eastbound drivers on US-95 have been seen illegally crossing the unpaved median to turn left into the access near the Nez Perce Express gas station, rather than traveling a half mile further to use the interchange. Some have even waited in oncoming traffic to make the prohibited turn, risking head-on crashes.
In response, ITD has increased signage and added barriers to further deter travelers from making this movement while soliciting the support of law enforcement.
“Drivers must pay attention to posted signage and recognize that this is a change,” said Nez Perce Tribal Chief of Police Mark Bensen. “While adjustments take time, using the interchange correctly is essential for everyone’s safety. This solution is designed to be safer for all drivers and reduce the risk of serious crashes.”
The western access to Aht’Wy Plaza near the gas station is one way and does not allow left turns of any kind. Drivers looking to turn left into the plaza or to exit the gas station should use the interchange.
Proper Use of the Aht’Wy Interchange
Entering
- Take the Nez Perce Drive exit off the highway.
- Slow down and stop at the intersection.
- Turn onto Nez Perce Drive to access Aht’Wy Plaza.
Exiting
- Follow signs on Nez Perce Drive back toward the interchange.
- Use the appropriate exit ramp for Lewiston or Orofino.
- Accelerate down the ramp to highway level and safely merge with US-95 traffic.
ISP troopers continue to monitor compliance and emphasize that changes in driver behavior are necessary to prevent further incidents.
“Too many motorists are ignoring traffic control measures and creating serious risks to other drivers,” said ISP Lieutenant Ken Yount. “We will continue having a presence in the area to ensure compliance and improve safety.”
The interchange is part of a significant engineering initiative to enhance traffic safety and reduce collisions in an area historically prone to fatal accidents.
“This interchange was carefully designed and implemented to improve traffic flow and minimize conflict points, ultimately reducing the potential for severe crashes,” said ITD District 2 Engineer Doral Hoff. “These changes prioritize safety and efficiency for all drivers, and we strongly encourage motorists to use the interchange as intended to prevent further tragedies.”
A downloadable map is available to help drivers better understand the interchange and ensure safe travel.
