MDT is hosting an open house on Wednesday, December 10, to discuss Huntley Area Projects with members of the public and collect input. This event will be from 4 to 6 p.m. at Huntley Project Museum (770 Railroad Highway, Huntley, MT 59037) and will provide an opportunity to ask questions, view visuals of the proposed improvements, and engage with the project team.
Project Overview
Through Huntley Area Projects, the Montana Department of Transportation (MDT) plans to replace the deteriorating bridge over Twelve Mile Creek and make necessary roadway and safety improvements along Old Highway 312 (HWY 312), near Huntley. The new bridge will provide capacity for current and future traffic needs, and the roadway improvements will help address safety concerns.
The proposed project will be completed in two phases:
- Phase 1 (anticipated letting 2027): West of Huntley and Twelve Mile Creek Bridge.
- Phase 2 (anticipated letting 2028): East of Huntley.
