Salmon Lake Highway Reconstruction logo

In October 2021, the Montana Department of Transportation (MDT) hosted two opportunities to share information with the public about proposed improvements to Highway 83 along the east side of Salmon Lake as part of the Salmon Lake Highway 83 Reconstruction project. We presented information about the proposed roadway widths, how we plan to improve slopes and rockfall areas, and other safety improvements.

The public was provided with similar project information for both the online and in-person meetings.

Project Overview

The Montana Department of Transportation (MDT) will reconstruct Highway 83 along the east side of Salmon Lake beginning in 2022. The road was originally built in the early 1950s and is being designed to improve safety features. Safety improvements include constructing a wider roadway, improving the alignment, and improved slopes and ditches. The design includes:

  • Widen the highway and shoulders
  • Straighten curves, flatten hills, and minor shifting of the current roadway, where possible
  • Improve existing cut slopes (rock fall hazards)
  • Create drainage improvements
  • New signage and guardrail, as necessary

Construction is scheduled to begin in the fall of 2022 and is anticipated to be completed in the spring of 2024.

Construction Manager/General Contractor

MDT is using the Construction Manager/General Contractor (CM/GC) process to deliver this project.

  • MDT working with a design consultant, HDR, and the contractor is Kiewit Infrastructure Company
  • The project will develop a construction staging plan that preserves access and promotes mobility for residents and traveling public

There are many advantages to CM/GC. For area stakeholders one of the best advantages is that the road contractor hears firsthand about community concerns during construction like keeping the road open for safety (i.e., access for emergency response vehicles, etc.).

Montana's roads and bridges are mainly funded through a combination of federal (88.5%) and state/local (11.5%) funding sources. MDT receives no funding from Montana's general fund revenue. Federal road and bridge revenues are generated from the users of our highways through gasoline and diesel fuel taxes and apportioned to states through federal highway legislation.
