Ustick Road, McDermott Road to Black Cat Road

The Ada County Highway District (ACHD) is designing improvements for Ustick Road, McDermott Road to Black Cat Road and the Ustick Road and McDermott Road intersection. The purpose of this project is to improve traffic flow and increase safety for all users.

Ustick Road, McDermott to Black Cat

• Widen Ustick Road to two lanes in each direction, with a center turn lane and median islands where the center turn lane is not needed for access
• Construct curb, gutter, and a detached 10-foot-wide multi-use pathway with buffer on both sides of the roadway for pedestrians and bicyclists
• Install medians islands to calm traffic and provide access control where necessary
• Reduce speed limit to 35 mph
• Add stormwater basins to collect, treat, and infiltrate stormwater runoff

Ustick Road and McDermott Road

In cooperation with the Idaho Transportation Department (ITD) State Highway 16 Improvements Project, ACHD will expand and signalize the Ustick and McDermott Road intersection to include:

• Additional through lanes
• Dedicated right and left turn lanes on Ustick Road and dedicated left turn lanes on McDermott Road
• Curb, gutter, and multi-use pathways

McDermott Road has been realigned by ITD as part of their SH-16 extension project.

Ustick Road and Owyhee Storm Avenue

When ACHD presented the project in June 2024, the Ustick Road and Owyhee Storm Avenue intersection was included. It has since been removed as The City of Nampa received a grant to fund the intersection, allowing them to fast-track construction. This change also helps coordinate the intersection project with the ongoing Highway 16 expansion. (External link)

*Please note that the realigned portion of McDermott Road is now called N McDermott Bypass.*
