The Idaho Transportation Department’s (ITD) US 20/26 Corridor Study identifies the need for significant investment along this important east/west arterial that connects Boise to Caldwell, but funding for construction projects is limited and not available in the near future. When Costco Wholesale and adjacent developers identified a preferred site on the southeast corner of Chinden Boulevard and Ten Mile Road in Meridian, Idaho, it was determined that significant improvements were needed to support their planned developments. The US 20/26 Corridor Study identified the need for localized improvements and funding challenges to implement the improvements.


Costco Wholesale and the Idaho Department of Transportation partnered together to enter a Sales Tax Anticipated Revenue (STAR) Program Agreement, through which Costco would provide the funds for this project and earn the money back as sales are generated. Kittelson was heavily involved with coordination efforts between traffic agencies, public involvement, and keeping the project running smoothly. Innovation and imagination on the part of all participants paved the way for the success of this project, making way for quick construction.

The Outcome

Increased safety and mobility of Chinden Boulevard

Through collaboration between ITD, Costco Wholesale, and Kittelson, this project advanced from 5% design to completed construction in two years. The several miles of increased capacity, which includes bicycle and pedestrian facilities, will provide for future development and growth for the area and Chinden Boulevard is now a transportation facility that supports local economic vitality, promotes active transportation, and provides environmental protections to the area.
