Wapama Falls Bridge and Rancheria Falls Bridge Rehabilitation
Bridge beams and all other materials would be brought to the remote site of these bridges by helicopter. All salvaged and damaged bridge components will be flown out in multiple flights.
Neither of these bridges are historic as both were constructed after the 1997 flood. All work will be performed in consultation with the park hydrologist.
This project will repair both the Wapama Falls bridge and the Rancheria Falls bridge. The Wapama bridge requires reconstruction of the 70 foot western-most span of the bridge near Hetch Hetchy Reservoir which was washed away in a high water event October 25, 2010. Work will include the replacement of the stringers, decking, and railings. The Rancheria Falls Bridge was moderately damaged in the same event. Rehabilitation of this bridge would require the replacement in kind of 50 feet of decking and guard rails.
