Learn MoreThe highway
Idaho 16 will have two lanes in both directions with a center median barrier and 10-foot shoulders. Motorists will be able to get on or off Idaho 16 at I-84, Franklin Road, Ustick Road, U.S. 20/26 and Idaho 44.
A network of local roads will provide access to and from neighborhoods and businesses. Idaho 16 will cross over Cherry Lane and McMillan Road.
This project is part of Idaho Governor Brad Little’s “Building Idaho’s Future” transportation funding solution.
A phased approach
The corridor will be finished in multiple phases. This approach will provide local access and regional mobility sooner.
Phase 1 opened in 2014. It included building a bridge over the Boise River and constructing the highway between U.S. 20/26 and State Highway 44.
Phase 2 includes finishing the remaining five miles of the highway, building bridges over local roads, and laying the groundwork for interchanges, which will be constructed in a future phase. Construction of Phase 2 could begin as early as Spring 2022.
Community input
ITD worked side by side with other transportation agencies, the development community and the public for many years to develop the vision and design for Idaho 16. The process has included a series of community workshops and public meetings. Click here to visit the most recent online meeting.
