State halts work on Interstate 15 in Wolf Creek for winter, will resume in 2025

Construction on Interstate 15 in Wolf Creek has paused for the winter, and will resume in 2025 when crews return to apply a seal and cover (chip seal) to the roadway, state officials said Monday.

Construction on this project began in 2023 with refurbishing about 8 miles of the southbound lanes of I-15 through the Wolf Creek Canyon. In 2024, crews repaired the northbound lanes of the interstate, adjacent ramps, pullouts and crossroads.

Other work completed included adding roadside markers, replacing right-of-way fencing and cattle guards, adding new pavement markings, lining and repairing I-15 culverts, improving erosion control features, upgrading storm drainage in Wolf Creek, updating curb ramps in Wolf Creek, and upgrading concrete barrier rails, metal guardrail and signage.

"With the pause in construction this season, the majority of work on the project has been completed," Kas Manderle, Great Falls district engineering project manager with the Montana Department of Transportation, said in an email.

Crews in 2025 will complete miscellaneous work, including application of chip seal, which will help preserve the new pavement.

When construction resumes in 2025, traffic control will return to the project area.
