Mullan BUILD Project

Missoula County and the City of Missoula combined efforts to apply for a Better Utilizing Investments to Leverage Development (BUILD) Grant to make infrastructure improvements in the Sxwtpqyen Area, which is generally the Mullan Road area west of Reserve Street and south of Broadway. The project was awarded $13 million in federal funds for infrastructure installation, including installing water and sewer utility infrastructure and road and trail construction, which was coupled with $8 million of local funding from the City and County to support this first phase of the Mullan BUILD project construction. The network of streets planned for the area will be built to improve connectivity and provide access to current and future homes and businesses. The BUILD project will ultimately play an integral role in how Missoula grows. For project details and background information, visit

Construction resumed the week of March 13, 2023, and will continue through June, weather permitting. Updates will be provided regularly on construction progress and anticipated delays. 

The week of March 20 – 24, drivers will continue to see crews near the Mary Jane Boulevard and Mullan Road roundabout. Crews will be removing the detour on the south end of the roundabout and begin work on sidewalks and bike lanes in this area. Drivers may experience minor delays.


SLOW DOWN in the work zone and be mindful of workers, nearby students, and other vehicles.

Mary Jane Boulevard North

Kiewit Corporation, project contractor, crews will install sidewalk and bike lanes, trail, lighting, chip sealing, and pavement markings.

The Montana Department of Transportation (MDT) has a separate project on West Broadway, and crews are installing a signal at the intersection of Mary Jane Boulevard and West Broadway, weather permitting. The MDT project also includes improvements at the intersection of Flynn and West Broadway, requiring traffic control along West Broadway.  Please follow traffic sign information for detours and local access. Please drive the posted speed limit and watch for workers and equipment near the roadway. Questions? Please contact

Mary Jane Boulevard South & Roundabout

The week of March 13, crews will be present around the roundabout at Mary Jane Boulevard and Mullan Road to install curb, gutter, and lighting. Drivers will not be impacted as crews will be off the roadway.

George Elmer Drive & Roundabout

Crews will complete necessary sidewalk and bike lane installation, trail construction, lighting, chip sealing, and pavement markings.

England Boulevard

Beginning in March, crews will complete the street extension of England Boulevard that will connect Flynn Lane and George Elmer Drive.

Mullan Road

Mullan Road's two roundabouts are almost fully completed with lighting, sidewalks, landscaping, and RRFBs (rectangular rapid-flashing beacons) at both roundabouts to be installed in spring of 2023, and some paving, curb, and median islands will be installed on the George Elmer roundabout. Drivers will also notice utility work and roundabout lighting installation beginning along Mullan Road.

Delays of up to 10 to 15 minutes can be anticipated when traveling throughout the project area from March to June, weather dependent. 


Roundabouts move traffic efficiently. As a reminder, please slow down, yield, and look left when approaching the roundabout. Drivers within the roundabout have the right of way. Once clear, enter the roundabout. Prior to exiting, put your blinker on to indicate to other drivers where you intend to exit the roundabout. The idea is that movement occurs continually through the roundabout to keep traffic flowing.
