Project Overview

US Highway 93 (US 93) is a vital transportation corridor for many growing communities in the Flathead and Bitterroot Valleys. With increasing traffic volumes, especially during the busy summer months, the US 93 corridor is a priority for the Montana Department of Transportation (MDT) Missoula District. This includes the US 93 North – Post Creek Hill project.

MDT and its partners are currently in the design phase of the US 93 North – Post Creek Hill project that will reconstruct US 93 from Red Horn Road/Dublin Gulch Road to Gunlock Road/Olsen Road to include safety and accessibility enhancements and wildlife accommodations.


  • Widening the roadway to include 8-foot-wide shoulders.
  • Constructing a northbound truck climbing lane at Post Creek Hill.
  • Constructing left-turn lanes at major intersections.
  • Installing a new bridge over Post Creek that facilitates wildlife movement underneath the highway.
  • Constructing a shared-use path.


MDT is partnering with the Confederated Salish and Kootenai Tribes (CSKT) to complete the US 93 North – Post Creek Hill project. This partnership symbolizes MDT’s commitment to preserving Montana’s natural heritage and collaborating with its communities. Recognizing the importance of clear communication and mutual understanding, MDT will work closely with stakeholders to provide updates regarding the project’s development. MDT also recognizes the need to begin this project and is using an interactive alternative contracting method to complete the project. This process allows MDT, CSKT and the design engineers to work with construction contractors from the start of the project. This will allow the project to move efficiently through the design phase to construction. Through this design/build method, the project team will be able to develop better solutions, reduce project costs, and maintain quality while expediting project delivery.

A public open house is planned to share project information and allow the project team to gather feedback, answer questions, and hear the community's concerns. More information will be provided closer to the anticipated date. Please continue to check this website for these dates.

Design Team

MDT is working alongside a team of Montana-based engineering experts to develop a highly complex project. Partners include Morrison-Maierle, Inc., SK Geotechnical, Kiewit Infrastructure Corp., Krebs Corp., KLJ Engineering, and DOWL.


Construction is tentatively planned for 2027. This schedule is subject to change due to funding availability, completion of the final design, and other unforeseen factors.

In the meantime, the public is encouraged to reach out with thoughts and questions by calling the project hotline at 406-207-4484, operating Monday through Friday from 9 a.m. to 5 p.m., or by emailing katieXYZbigskypublicrelationsABCcom.
