County Bridge Maintenance

Let us know your thoughts or questions on the maintenance of a bridge near you.

If you see a bridge that needs maintenance that isn’t on the County’s radar yet, drop a pin on our interactive map to let us know about it.

In accordance with state law, Missoula County maintains all bridges and culverts in the County—even those within city limits—not already maintained by the Montana Department of Transportation. This adds up to 474 bridges and culverts. Bridges maintained by MDT include any that are on state highways or roads, like Beartracks Bridge and the Reserve Street Bridge.

Funding to provide bridge maintenance is limited and has proven to be a challenge. Staff prioritize maintenance based on traffic level and maintenance urgency, such as if the concern poses a safety risk. Bridges of high public interest, like the Maclay Bridge/future South Avenue Bridge in Target Range or Lolo Street Bridge in the Rattlesnake, have their own Missoula County Voice pages. Otherwise, all other bridges with maintenance planned in the coming years or planned replacements are listed on this page.

If you see a bridge or culvert that you think may need maintenance, drop a pin on the interactive map below to let staff know. Though we may not be able to address the problem immediately, staff still appreciate being made aware of the problem.

And of course, if you have questions, please view the “frequently asked questions” section on the right-hand side, and if your question isn’t answered there, send it to us below!
