SH-54 Reconstruction from Spirit Lake to Athol

This project will fully reconstruct existing State Highway 54 between Spirit Lake and Athol and will add additional shoulder width, turn lanes, and illumination throughout the corridor.

SH-54 Reconstruction from Spirit Lake to Athol

This project will fully reconstruct existing State Highway 54 between Spirit Lake and Athol and will add additional shoulder width, turn lanes, and illumination throughout the corridor.

UPDATE

 

Paving operations are nearly complete on the newly constructed portion of the highway between Athol and Spirit Lake East.

 

By Friday (7/31), traffic will be shifted to the newly paved surface and the temporary traffic signals will be removed allowing for the return of uninterrupted, two-way traffic flow.

Overview

This project will fully reconstruct State Highway 54 between State Highway 41 and Greystone Road to restore a safe, smooth driving surface between Spirit Lake and Athol. Improvements will include added turn lanes, wider shoulders, updated signage, lighting, and delineators throughout the corridor. Early construction activities, including utility relocations and tree removal, began in late 2024 to prepare for full roadway reconstruction, which is expected to be complete in late 2026.

Project Information

This project will be split into two phases with an anticipated completion date in 2026.

Once completed, the improved section of roadway will increase safety, enhance vehicle capacity, and position the corridor to successfully accommodate future growth in the area. The ultimate configuration of the highway will remain a single lane in each direction after construction is complete.

2026 Construction Update

Construction is now underway for the 2026 season on SH-54 between SH-41 and Greystone Road, with crews actively working along the south side of the highway through June.

Work will start by building up the road base, followed by placing gravel and paving. During this time, drivers should expect this work to impact their commute, including:

  • Single-lane traffic controlled by a temporary signal, operating 24/7 to allow one lane to pass at time for several weeks in early to mid-June. This work will span approximately 1/2 mile of highway.
  • Intermittent flagging operations.
  • Trucks entering the highway.

Crews will also be working on driveway approaches, culverts and new lighting along the roadway.

Once the south side is paved and striped, traffic will move onto the new lanes and return to two-way traffic. This is expected around early July. Crews will then begin work on the north side of the highway.

The right-of-way area adjacent to the highway will remain closed to pedestrian and recreational traffic including bicycles, motorbikes, and ATV’s for safety.

Final completion of this project is expected by the end of 2026.
