Ustick Road Corridor

Ustick Road is one of the longest continuous corridors in the Treasure Valley. The 37-mile roadway connects the communities of Caldwell, Nampa, Meridian and Boise. Seven miles of this corridor are located in Nampa.

As the Treasure Valley continues to grow, traffic on Ustick Road in Nampa is expected to increase by more than 500 percent.

The City of Nampa is making this corridor a priority as our community continues to grow and thrive.

The City of Nampa will widen and improve Ustick Road between the Phyllis Canal (just south of Can Ada Road) and Owyhee Storm Avenue.

Construction is planned to begin in late spring 2025 and continue for about 18 months.

The next few slides show the planned improvements to Ustick Road between the Phyllis Canal and Owyhee Storm. Slide the arrows left and right to see Ustick Road before and after construction. Click each image to zoom in or out.

Between Can Ada Road and Owyhee Storm Avenue, we expect that Ustick Road will be open for the majority of construction. Flaggers and short-term detours may be necessary.

More information will be available this spring as soon as a contractor is on board.

The City of Nampa is working closely with the Ada County Highway District and Nampa Highway District No. 1 to continue improving Ustick Road for motorists, pedestrians and cyclists.

Construction along this corridor is expected to continue over the next several years.
