A long-vacant lot near Interstate 90 will be transformed into one of Montana’s largest mixed-use developments, with groundbreaking scheduled for 2026.

The project, called Bozeman Square, will span 31 acres from the former K-Mart site on 7th Avenue east to the Gallatin County Fairgrounds along Oak Street. The development will eventually contain more than 1 million square feet of residential, commercial, arts and entertainment space, along with a potential convention center, hotels, and restaurants.
