Salmon Lake Highway 83 Reconstruction Update Schedule

Due to survey discrepancies identified during early construction, there are three sections of the project that required design changes. MDT, Kiewit, and HDR are working together to finalize the design in these areas while also ensuring that ongoing construction work is not disrupted.

Design – Design changes on the two southern segments are complete and construction will be completed this summer. The design of the north end of the project is currently underway. As the extent of the design changes are identified, the project team will determine how much work can be completed this season, and what work will need to be completed in 2024.

Construction – Favorable fall weather will allow crews to complete approximately three miles of roadway along the southern end of Salmon Lake. Over the 2023/2024 winter, MT 83 will be paved and open to two-way traffic. Woodworth Road will not be paved. MDT anticipates completion of the north, and final segment, by July 4, 2024, weather and other factors permitting.

Project Overview

Salmon Lake image

The Montana Department of Transportation (MDT) and its construction partner Kiewit has begun reconstruction of about four miles of Montana Highway 83 (MT 83) along the east side of Salmon Lake. Roadway safety improvements will:

  • Increase visibility.
  • Widen the highway to include paved shoulders.
  • Straighten curves and flatten the roadway profile.
  • Improve existing cut slopes to reduce rockfall hazards.
  • Create drainage improvements.
  • Install new signage and guardrail.

Tree clearing in the project area was completed late-August 2022. Construction has started this year with final construction activities wrapping up in the spring of 2024.

Project Purpose

The Montana Department of Transportation (MDT) will reconstruct Highway 83 along the east side of Salmon Lake. The project purpose is to:

  • Upgrade the existing roadway to accommodate current and projected motor vehicle traffic
  • Better facilitate bicycle travel
  • Enhance roadside safety for all users

The project is also needed to address the deteriorating pavement, lack of shoulders, and difficult roadside environment along some segments.

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.
