SH-16 to fully close this weekend between SH-44 and US-20/26

Aerial view of an active highway construction site with multiple excavators, loaders, and work trucks operating on a large dirt area. Crews wearing safety vests work near a newly installed concrete box culvert. Construction materials, trailers, and equipment are scattered around the site. In the background, vehicles travel along a nearby highway, and autumn-colored trees and residential buildings border the work zone under clear blue skies.

State Highway 16 will be fully closed south of State Highway 44 the weekend of Nov. 7-10 as the Idaho Transportation Department installs a drainage structure underneath the highway. SH-16 will be closed between SH-44 and US-20/26. Traffic will be detoured to Star and Linder Roads.

Closures will begin at 9 p.m. Nov. 7 and will end at 5 a.m. Nov. 10. Work will result in significant noise during this time.

Crews will install a drainage structure, also called a box culvert, underneath SH-16. The structure will be 495 feet long and comprised of 86 individual pieces, each measuring 8 feet wide by 6 feet tall and weighing an average of 22,500 pounds.

The culvert is being installed as part of the work on the future SH-16/SH-44 Interchange, which will connect SH-16 to Interstate 84. The new SH-16 corridor is on track to open in 2027.
