We’re thrilled to have played a part in setting the stage for professional soccer in Idaho! To help transform the historic Les Bois Park horse racing facility into a professional soccer stadium, the Cushing Terrell team brought its architectural, structural engineering, and interior design capabilities to the endeavor.
The goal of the adaptive reuse project was to modernize and expand the existing structures, develop new spaces and systems necessary to support new uses, and make accessibility improvements to create world-class amenities for the soccer players and their fans.
The stadium is now home to Boise Pro Soccer's USL League One men’s team; and in the fall of 2027, a USL Super League women’s team will join them. The FIFA-certified facility will be soccer-focused, with plans to redevelop all 27 acres of the Ada County, Idaho-owned site into a dynamic mixed-use venue over several phases.
“This site has a lot of history and being able to continue its legacy while transforming it into something new through adaptive reuse is really rewarding,” said Allison Clark, a Cushing Terrell design professional who supported the project. “The site is taking on a new life and will be enjoyed by new generations of people, inspiring kids across the Treasure Valley to take up soccer.”
Congratulations to Athletic Club Boise, and a big thank you to our exceptional project partners Okland Construction and Engineering Consultants, Inc.!
