Good news—all lanes open

All lanes will reopen on Highway 15 between St. Augusta and Kimball by Friday morning, July 26.

The road has been detoured since May 6.

Motorists traveling through the area are reminded that it takes time to open and remove a detour. Be alert for changes, watch for heavy moving equipment and crews removing temporary signs and barricades.

You may encounter crews working in areas along Hwy 15, as they complete off-road work through Aug. 2.

Summary of work

  • Reconstruct 12 miles of Hwy 15 road surface (full-depth reclaim), includes shoulders and turn-lanes

Equipment used to reclaim road surface
Full depth reclamation, uses equipment often described as a rototiller for pavements.

Hwy 15

This project used a long lasting and cost effective road surface treatment known as stabilized full depth reclamation, which uses equipment often described as a rototiller for pavements. The asphalt pavement and some of the existing soil base is ground together in-place. Two passes of the reclaimer were used. Once the reclaimed base was done, crews paved over the base with two new layers of asphalt.
