WOLF CREEK, MT — The Montana Department of Transportation (MDT) and Riverside Contracting will begin a project to rehabilitate approximately seven miles of Interstate 15 (I-15) near Wolf Creek. The project area begins approximately five miles south of Wolf Creek and extends north to the Augusta Interchange (Exit 228). This project is anticipated to begin in early April 2023 and take three construction seasons to complete.

The purpose of the project is to improve the driving surface and enhance roadway safety on this seven-mile stretch of I-15. The extreme climate and numerous freeze/thaw cycles in Wolf Creek Canyon have caused the roadway material to degrade to the point where routine maintenance is no longer practical.

Planned improvements include:

• Removing and replacing the top two feet of degraded roadway material and resurfacing adjacent ramps, crossroads, and pullouts
• Upgrading concrete barrier rails, metal guardrails, and signage
• Adding road delineators (roadside markers) on inside curves
• Replacing right-of-way fencing and cattle guards as needed
• Updating curb ramps on Walsh Street between Main Street and Recreation Road
• Upgrading storm drainage in the town of Wolf Creek
• Lining and repairing I-15 culverts
• Improving erosion control features
• Adding new pavement markings

The project was awarded to Riverside Contracting, with a bid of $39,200,000. The project is funded with 87 percent federal funding and 13 percent state funding.
