The Montana Department of Transportation (MDT) and Riverside Contracting Inc. is improving approximately 8 miles of Interstate 15 (I-15) near Wolf Creek. The project area begins 5 miles south of Wolf Creek and extends north to the Augusta Interchange.

Project Map

The project will rehabilitate the roadway, update existing guardrail and concrete barriers to meet modern standards, and upgrade storm drainage in the town of Wolf Creek.

Construction began in spring 2023 and is expected to be completed in 2025.

Work completed in 2023-2024:

  • Removed approximately two feet of degraded roadway material on the north and southbound lanes of I-15 and paved new driving surfaces
  • Paved adjacent ramps, crossroads, and pullouts.
  • Upgrading concrete barrier rails, metal guardrails, and signage on the north and southbound lanes.
  • Adding road delineators (roadside markers) on the inside curves of the north and southbound lanes.
  • Improving erosion control features.
  • Replaced right-of-way fencing and cattle guards as needed.
  • Improved drainage by lining and repairing I-15 culverts.
  • Improved erosion control features and storm drain upgrades in Wolf Creek.
  • Updated curb ramps on Walsh Street between Main Street and Recreation Road.

Planned improvements for 2025:

  • Add new pavement markings.
  • Replacing signage.
  • Add a seal and cover (chip seal) to the roadway.

Why is the project needed?

MDT identified this stretch of interstate as being worn down and in need of repairs. The purpose of this rehabilitation project is to extend the service life of the roadway, provide a smoother driving surface, and improve signage and markings for the roadway. The project will also upgrade roadside barriers and reduce issues that require regular maintenance within the corridor. The upgraded signage and roadway markers were included as part of this project to enhance safety features along this corridor.
