BIG SKY, Mont. — The Montana Department of Transportation (MDT) is announcing and inviting the public to comment on a proposal that will rehabilitate about 14 miles of US Highway 191 (US 191), north of Big Sky. The project begins at mile marker 47.3, and extends north, ending near mile marker 61.3 at the Lava Lake Structure.
Proposed work includes guardrail embankment repair, subgrade dig outs, milling the existing surface, applying a new overlay, and finishing with a seal and cover (chip seal), upgraded pavement markings, signage, and guardrail. The purpose of the project is to repair the existing surface, enhance roadway safety features, and prolong the service life of the roadway.
Construction is tentatively planned for 2026 depending on completion of design and availability of funds.
Partnering with the community is an important part of properly planning for future projects. MDT welcomes the public to provide ideas and comments on the proposed project. Comments may be submitted online at mdt.mt.gov/contact/comment-form.aspx or in writing to Montana Department of Transportation, Butte office, PO Box 3068, Butte, MT 59702-3068. Please note that comments are for project UPN 10558000.
The public is encouraged to contact Butte District Preconstruction Engineer Brandon Jones at 406-494-9622 with questions or comments about the project.
