Future SH-16/Ustick Road Interchange Update:
Earlier this month, crews set 13 concrete girders over Ustick Road for the future SH-16/Ustick Road Interchange.
Watch the video below to see the girders being set!
Overview
The Idaho Transportation Department is constructing the extension of State Highway 16.
Upon completion, this limited-access highway extension will run from north to south between SH-44 and I-84.
The entire corridor is on track to open in 2027.

Current Construction
ITD is building a new highway with two lanes in both directions, a center median barrier and 10-foot shoulders.
The highway will be elevated between 5 and 20 feet off the ground. Motorists will use freeway interchanges to enter or exit SH-16 at:
- I-84
- Franklin Road
- Ustick Road
- US-20/26
- SH-44
Anticipated Construction Impacts
- Occasional closures or delays on roads in the project area.
- Some work will be scheduled at night and will require nighttime noise and lighting.
- Vehicle traffic will increase in the area during construction.
- Work will be noisy at times.
- Access to businesses, residential areas and irrigation will remain open.
- Flaggers will direct traffic through the work zone when necessary.
- Utility companies may interrupt traffic when relocating infrastructure.
Funding
Current construction is funded in part with Transportation Expansion and Congestion Mitigation (TECM) funds as part of Governor Little’s Leading Idaho TECM Program. The program allows ITD to accelerate project timelines to address rapid growth and build critical infrastructure today that would otherwise take many years to fund and build.
Other Projects in the Area
State Highway 16 is one of many infrastructure projects in the central Treasure Valley. ITD and other agencies are working together to meet the needs of this growing area.
