The Montana Department of Transportation (MDT), in partnership with Frontier West, Robert Peccia & Associates, and Morrison-Maierle, is resuming construction on the Timber Bridges – Forsyth Area project on U.S. Highway 12 between Forsyth and Ingomar. The project will replace aging timber bridge structures with two new bridges and 12 reinforced concrete culverts, improving long-term safety and accessibility along the corridor.

Why it matters

The Timber Bridges – Forsyth Area project is crucial for ensuring reliable access and transportation safety for residents, emergency services, and agricultural traffic in the region. The upgrades will remove existing weight restrictions and enhance roadway safety features, supporting the community's needs for years to come.

The details

Construction will begin on Monday, March 23 on Bridge ID 5495, the Middle Fork Froze to Death Creek Bridge, located 2.5 miles west of Ingomar on US 12. Crews will be moving gravel from several other bridge sites to build a temporary detour around Bridge ID 5495 and prepare additional bridge sites for work. The public should expect traffic control measures, including temporary detours, single-lane closures, and occasional width restrictions.

  • Construction will begin on Monday, March 23, 2026.
  • Further construction planned for 2026 includes paving at the bridges currently surfaced with gravel.
