State 45 Study

Thank you for your interest in State Highway 45.

The City of Nampa is identifying and analyzing improvements to address safety, congestion, mobility, and travel time reliability in downtown Nampa. This study focuses on State Highway 45 (SH-45), an important route for agribusiness and freight. 

The City thanks every person who participated in open houses for this project in April 2022 and/or August 2021. Comments from the most recent open house will help the project team evaluate potential options for State Highway 45. The resulting options will be studied in more detail in the future. Community members are encouraged to review materials and email comments by April 29, 2022 to [email protected] You can also download and email or mail the comment sheet to the Office of the Mayor (411 3rd Street South, Nampa ID 83651).
