MERIDIAN – The Idaho Transportation Department will complete a major milestone along the State Highway 16 corridor later this week. Crews will set 13 girders for the future SH-16 and Ustick Road Interchange. To minimize traffic impacts and ensure space for safely completing this work, Ustick Road will be closed at night on Wednesday, Feb. 4, and Thursday, Feb. 5.  

What to expect Wednesday and Thursday:  

• Ustick Road will be closed from 7 p.m. to 5 a.m. each night between Owyhee Storm Avenue and McDermott Bypass.  

• Traffic will be detoured to McMillian Road and Cherry Lane. Click here for the detour map.  

• Access to homes within the closure area will be maintained.  

“Placing the girders is a major milestone in the project and a critical step toward completing the interchange on schedule.” Resident Engineer Dan Gorley said. “We are making steady progress and appreciate everyone’s patience as we continue to build the SH-16 corridor.” 

ITD anticipates that the Ustick Road interchange will be completed in 2027 along with the entire SH-16 corridor.  SH-16 will improve regional mobility, provide access to I-84 in the rapidly growing central Treasure Valley, and improve commutes for thousands of motorists. Upon completion, this limited-access highway extension will run from north to south between SH-44 and I-84.
