Full Closure of S. 3rd Ave Starting This Week

BOZEMAN – Construction is underway on the City of Bozeman’s West Kagy to Babcock Sewer Improvements project. Crews are working 24-hour shifts to complete work at the South 3rd Avenue/West Kagy Boulevard/South Willson Avenue intersection before the school year begins.

Starting late next week, a full closure of South 3rd Avenue will be implemented while construction crews work on the manhole on the southeast corner of the intersection, near Crossings Kitchen. South 3rd Avenue will be closed to all directions of traffic between the West Kagy Boulevard intersection and West Graf Street but will remain open for local residents and business access. Detour signs will direct northbound through traffic on South 3rd Avenue to take West Graf Street to South 11th Avenue.

When work at the South 3rd Avenue/West Kagy Boulevard/South Willson Avenue intersection is complete and the intersection is reopened, crews will begin working on the West Kagy Boulevard and South Tracy Avenue intersection. The public can expect intermittent closures along South Tracy Avenue beginning the week of August 24, weather and other factors permitting.

In addition to the upcoming closures on South 3rd Avenue and South Tracy Avenue, the City of Bozeman has issued the following travel advisories:

Starting this week, there will be intermittent closures of the westbound left-turn lane from West Kagy Boulevard into the Museum of the Rockies’ (MOR) main entrance. During these closures, signs will be in place directing westbound MOR visitors to take South 7th Avenue into the museum’s staff parking lot and then follow the service drive to the visitor parking lot.

Access to the business center at the corner of West Kagy Boulevard and South 3rd Avenue is and will continue to be available throughout construction.

Pedestrians and bicyclists must follow all traffic control and posted signage. Barricades and other devices are in place to maintain worker and public safety.

The purpose of the West Kagy to Babcock Sewer Improvements project is to replace aging sewer pipelines to maintain a resilient and reliable sewer system in southwest Bozeman. The project will be completed in two phases over the next couple of years, beginning with the West Kagy Boulevard upgrades this summer. The next phase of the project includes sewer improvements in a residential area between West Babcock and West College Street—near Cooper Park—which is tentatively planned for spring 2027.
