GRAND CANYON, Ariz. – Grand Canyon National Park will lift trail closures related to the Transcanyon Waterline Replacement Project at 7 a.m. Friday, June 26, five days ahead of schedule.

The closures are being lifted following the completion of reconstruction work on the River Trail, which was damaged by a rockfall during work associated with the Transcanyon Waterline Replacement Project. The rockfall required additional geologic hazard assessments, new design features and engineering work before the trail could be rebuilt and this portion of the project could be completed.

Trail closures related to the project will remain lifted for the duration of the summer months. Future closures associated with the Transcanyon Waterline Replacement Project are planned to begin in mid-October 2026. Visitors can learn more about current and future closures via the park’s Transcanyon Waterline Replacement Project webpage.

The Transcanyon Waterline Replacement Project is one of the largest and most complex infrastructure projects in the history of Grand Canyon National Park. Visitors should continue to check the park’s website for current trail conditions, project updates and closure information before beginning their trip.
