National Park Service completes road construction to repair damage after landslide
Kolob Canyons Road is open! In collaboration with the Federal Highway Administration, the National Park Service completed work to:
- Excavate unstable materials and reinforced the road’s base to a depth of eight feet with geo-grid, structural cloth, and compacted soil.
- Repave more than 6,000 square feet of pavement.
- Install ditches, gutter, and curbs to drain the road more effectively.
This construction repaired damage from a landslide and reinforced the road to proactively increase resilience ahead of future weather or geologic events.
Background
In March 2023, rangers observed a depressed area on the road and closed it as a precaution. Shortly thereafter, the road began to collapse. The National Park Service worked with engineers from the Federal Highway Administration to assess the site and develop a plan to rehabilitate the road.
The National Park Service began work to rehabilitate the road in September 2023.
