STAR—The Idaho Transportation Department will shift traffic and reduce State Highway 16 to one lane in each direction between the Boise River Bridge and State Highway 44 on Sunday. These traffic changes will allow crews to prepare and place concrete for SH-16 and build the northbound off-ramp for the new interchange.
Motorists can expect:
- Northbound SH-16 traffic will be shifted onto the southbound lanes.
- All lanes of SH-16 will be open at the intersection with normal traffic operations
- The speed limit will be reduced to 55 mph.
Motorists are advised to use caution and plan extra time when traveling through the area.
“This is a challenging work zone, and we are actively looking at ways to improve traffic flow through the area,” said Styles Salek, ITD Design and Construction Engineer. “The new layout next week will allow us to complete the next two phases of construction. This helps our crews work more efficiently and reduces the number of traffic shifts during construction.”
The SH-16/SH-44 Interchange began construction in August 2025 and is part of the long-term vision for SH-16. When complete in 2027, SH-16 will be a limited-access freeway between I-84 and SH-44. Motorists will use interchanges to enter or exit the highway at I-84, Franklin Road, Ustick Road, US-20/26 and SH-44. The interchange project is $55 Million.
Motorists are encouraged to text HIGHWAY16 to 1-866-483-8422 for email or text alerts. For maps and details about the project, please visit itdprojects.idaho.gov/pages/sh16corridor.
