About the Gallatin County
Road & Bridge Department
The Gallatin County Road Department is funded in by a mill levy assessed on property owners within Gallatin County but outside established city limits, as well as by gas tax revenue received from the State of Montana. The Bridge Department receives budget authority through the general fund. The two departments work together in the same location, along with the Junk Vehicle Department.
With the limited budgets, the Gallatin County Road & Bridge Departments employ 34 people including equipment operators, mechanics, and administrative staff. This department is responsible for the maintenance of over 200 roads totaling over 800 centerline miles, over 200 bridges, including those within city limits, and approximately 5,000 culverts.  
Work is performed on County maintained roads and bridges, and does not include the following road systems:
~ Subdivision roads (public roads maintained by the residents, usually through a homeowner association or an RID)
~ Private roads and bridges (privately owned and maintained by residents)
~ City roads (maintained by the city)
~ State highways (maintained by the Montana Deptartment of Transportation).
If you want to know whether a road is maintained by Gallatin County, you may call us at 406-582-3250.
