Project Overview
The Montana Department of Transportation (MDT) and the City of Bozeman, in cooperation with Montana State University (MSU), the Museum of the Rockies, and other stakeholders, have initiated a project to reconstruct Kagy Boulevard from South 19th Avenue to Willson Avenue.
The project is still in the early design stages and community outreach opportunities will be updated on this page as they are scheduled. Public engagement opportunities concluded in May of 2023 and the design team has been working with the project stakeholders to update the design and assess feasibility of different project components.
South Bozeman has experienced significant growth and is expected to continue doing so as the enrollment at MSU increases and housing needs in the area continue to grow. Kagy Boulevard is the primary east-west route in this area and is expected to serve a large portion of the developing community.
Current Status
In December 2023, nearly $24.3 million in Rural Surface Transportation Grant funding was secured to reconstruct and enhance safety features on Kagy Boulevard. As of February 2025, the Montana Department of Transportation (MDT) and the City of Bozeman are working with Sanbell (formerly Sanderson Stewart) to complete the preliminary 30% design. Upon completion, the contract will be converted to a Design-Build contract to comply with federal grant requirements. Design-Build projects conduct both final design efforts and construction under one contract, rather than separate design and construction teams.
This project will reconstruct Kagy Boulevard from South 19th Avenue to South Willson Avenue, including two travel lanes in each direction, turning lanes/median, a separated shared-use path on both sides of the roadway, landscaping and street lighting, roundabouts, pedestrian grade-separated and at-grade crossings, and signal modifications. Intersection improvements include layout and signal modifications to the South Willson Avenue intersection along with two multi-lane roundabouts: one at the South 11th Avenue intersection and another at the South 7th Avenue intersection.
The following typical section illustrates recommended multi-lane design concepts for the project corridor.
Preliminary design and approval are anticipated to continue through the summer of 2025, at which point right-of-way acquisition will begin. Construction is anticipated to start no later than 2027, dependent on completion of design and any unforeseen factors.
