On or after Monday, Sept. 25, the National Park Service will start a project to repair damage that resulted from a landslide earlier in the year.

“Engineers and park maintenance staff developed the plan to repair the road in collaboration with the Federal Highway Administration,” Zion Chief of Facilities Management Bry Carter said in a news release. “Just like all construction in the park, we are going to ensure this work complements the natural landscape and improves visitors’ experiences.”

Work is scheduled to be finished in winter 2023, but completion is dependent on the weather and availability of supplies. We will share more information as the project progresses. The project will involve:

  • Excavating unstable materials and reinforcing the road’s base to a depth of 8 feet with geo-grid, structural cloth and compacted soil.
  • Repaving more than 6,000 square feet of pavement.
  • Installing ditches, gutter and curbs to drain the road more effectively.

While construction is happening, the road and all trailheads next to it will be closed to drivers, hikers, horse riders and bicyclists. The closure is necessary so that the construction contractor can stage equipment, move soil and store supplies. Visitors are reminded not to enter the closed area and to contact Zion Wilderness Rangers if you had planned to use the Lee Pass Trailhead to access hikes or campsites on La Verkin Creek or Hop Valley Trails.

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.
