Grand Canyon National Park Plans Repairs to Indian Garden Pump House and Black Bridge
Beginning in mid-February the National Park Service will rehabilitate the pump houses at Indian Garden and the Black Bridge near Phantom Ranch. Completion of both projects is anticipated in mid-April. These projects may temporarily disrupt backcountry users.
Beginning around February 15 at Indian Garden, crews will replace the roof-mounted HVAC units and the roofing system on both water pump houses. The replacement of the HVAC units is critical to ensure continued operation of the water pumps that supply water to the South Rim. Replacing the roofs, which have deteriorated due to heat and a harsh environment, will help protect the integrity of the buildings. Bright Angel Trail has been temporarily rerouted from the construction area to maintain visitor safety.
Around March 7 NPS trails crew will rehabilitate the Black Bridge, also called the Kaibab Suspension Bridge, across the Colorado River. At the end of the South Kaibab Trail, the Black Bridge is used by hikers and mules to access the Phantom Ranch area and continue on the North Kaibab Trail.
The work on the Black Bridge will replace decking and wooden tread boards, which over time have become rutted and made the walking surface uneven. NPS trails crew last replaced the decking and tread boards in 2006. Work is anticipated to last until mid-April.
While crews complete the repairs, hikers may experience delays or detours; there is no anticipated bridge closure. Crews will time their work around the arrival of mule trains to allow unimpeded mule traffic.
For both repair projects, inner canyon trail users may experience detours, temporary delays, and noise and dust from equipment and helicopters. To reduce the number of helicopter flights, both projects will use a medium-lift helicopter (K-MAX) to haul supplies and equipment. The park helicopter will also be used as needed. Hikers, campers, and mule riders should listen to and follow directions from NPS staff as needed in the work zones.
