Perma bridge work nears completion

The Montana Department of Transportation (MDT) and Frontier West have substantially completed work on the Flathead River – Perma Bridge project. The goal of this project was to rehabilitate the bridge that carries Secondary Highway 382 traffic over the Flathead River near Perma. Traffic control has been removed over the bridge.

Crews will return later this summer to complete minor tasks and apply final pavement markings. Traffic control will be in place while this final work takes place. Travelers should expect intermittent single-lane traffic controlled by flaggers.

This project began in 2023 and took approximately two years to complete. Improvements included:

Replaced damaged bearings and joints.

Repaired girders.

Hydro milled and overlaid the bridge deck with new concrete.

Upgraded bridge railing.

Painted portions of the steel substructure to slow corrosion.

Installed advance warning rumble strips and signage for the intersection of S 382 and Montana Highway 200 (MT 200).

Paved bridge approaches.

MDT and Frontier West thank the public for their feedback and patience during this construction project.
