The Idaho Transportation Department will begin major work next week on the future State Highway 16 and Ustick Road Interchange. Starting Tuesday, May 27, Ustick Road will be closed from Owyhee Storm Avenue to McDermott Bypass until late August.
Motorists can expect that:
- Ustick Road will be closed between Owyhee Storm Avenue and McDermott Bypass.
- Traffic will be detoured around the work zone. Click here for the detour map.
- Access to homes within the closure will be maintained.
- Temporary traffic signals will be in place at the Cherry/McDermott and Ustick/Can-Ada intersections as requested by ACHD and the city of Nampa.
The closure will give crews room to widen Ustick Road immediately around the interchange and connect the on- and off- ramps for the interchange.
“Our goal is to complete as much work as possible while schools are out of session,” Project Manager Dan Gorley said. “We look forward to the completion of this interchange, and we thank the community for their patience during construction.”
The Ustick Road Interchange is anticipated to be completed in 2027. Intermittent lane closures will continue in the area over the next year.
