Project Improvements


The project team, led by local engineering firm, DJ&A, and Kiewit have completed a majority of the phase 1 construction in 2022. 100 percent design plans are located below for reference.


Knowing that Missoula County and the City of Missoula could not advance all portions of the project at this time, Mary Jane Boulevard South, Mary Jane Boulevard North, George Elmer Drive South, and England Boulevard were ranked as the highest priorities, that also meet the prerequisites. These areas have mostly been constructed and have utilized $13 million in federal BUILD Grant funds. Other identified improvements will be completed in the coming years as additional funding sources are secured. All project elements will be completed in additional phases once all necessary funding (via special impact fees or grants) and right-of-way has been acquired.

With that background in mind, the project team welcomes feedback and questions on the construction schedule and future project plans.  Please see below for links to each phase of the project design plans. Feel free to send any questions or comments to

Additional Funding Considerations: Impact Fees

As many know now, impact fees are a funding source to help support the remainder of the BUILD project. As of March 2, 2021 the City of Missoula approved the use of impact fees on new developments in the greater Mullan area. The addition of these impact fees will allow for more elements of the BUILD project to be completed in the coming years. Now that the ordinance has been adopted, fees will go into effect on March 31, 2021. for more details, please visit the Engage Missoula webpage
