Project Overview

The project is located in Missoula County on Montana Highway 83 and begins at Reference Post (RP) 9.0, about 1.1 miles south of Placid Lake Road, and just north of Salmon Lake. It extends northerly 4.1 miles to RP 13.1, about 0.2 miles south of the town of Seeley Lake. The beginning of this project will tie into future construction project, Salmon Lake, which is tentatively scheduled for construction in 2022 and 2023.

The project will reconstruct the road, which will provide improvements in the form of a new roadway surface, wider shoulders, turn lanes, safer roadside slopes, and a new bridge. The project includes the following safety improvements:

  • Constructing turn lanes at the Placid Lake Road, Double Arrow Ranch Road and Wagon Wheel Road intersections
  • Straightening the roadway alignment, where feasible
  • Replacing the bridge over Morrell Creek
  • Constructing a shared use path from Double Arrow Ranch Road to the northern end of the project
  • Other work will include tree clearing, guardrail upgrades, signing, flattening roadside slopes where possible, and increasing ditch size to better handle snow storage, drainage, and rockfall

Due to the highway’s location in this popular recreation and tourist area, MDT is committed to working closely with the public and stakeholders throughout the design and construction processes. There will be several opportunities to engage with the project team, and MDT encourages you to get involved, share your input, and learn more about this important highway improvement project.

The Montana Department of Transportation Maintenance Division performed an asphalt overlay of the existing roadway on Highway 83 within the project limits of Seeley Lake – South in mid-September 2022. The Maintenance project was intended to maintain the existing roadway surface until the Seeley Lake - South project is constructed. The Maintenance project was not associated with project Seeley Lake - South.
