Choteau US 89 project logo

What work is scheduled to occur near Choteau?

The Montana Department of Transportation (MDT) is currently redesigning three sections of US Highway 89 (US 89) near Choteau. The following improvements can be expected:

  • Repaving operations.
  • This project will address sharp curves and steep roadside slopes to enhance roadway safety features.
  • Widening roadway shoulders to improve traffic flow.
  • Some pullouts will be upgraded and may be used to view wildlife.
  • The Teton River Bridge will be replaced.

Where is work occurring?

All work will take place outside of the Choteau city limits.

  1. The first segment begins just north of the Choteau city limits and extends north for about seven miles.
  2. The second segment begins just south of the Choteau city limits and extends south for about six miles.
  3. The third segment is just south of the second segment and extends south for about six miles.

Why are there three segments?

Each segment is funded differently and will be completed at different times.

When will construction occur?

Construction on the first segment, north of Choteau, occurred in 2024 and is expected to resume in 2025. Construction on segment two is tentatively scheduled to occur in 2026 and 2027 and construction on segment three is expected for 2029. All work is dependent on the weather and other factors.

Will US 89 be closed during construction?

No, MDT will maintain US 89 access during construction. Once construction begins, motorists should anticipate traffic control and possible delays when traveling through the project area.
