Hetch Hetchy Water and Power is responsible for maintaining 14 bridges located in the Cherry, Eleanor, and Hetch Hetchy region. A condition assessment has identified the need for rehabilitation and/or replacement (both due to age and to meet current seismic design criteria). Four of the fourteen bridges require substantial modification or replacement and have been combined into this project.
The current 10-year Capital Plan funds work for only two bridges: O'Shaughnessy Adit Access Bridge and Lake Eleanor Dam Bridge.
The project is part of a larger Hetchy Capital Improvement Program (HCIP), a multi-year capital program to upgrade or improve water conveyance, water storage, and power generation facilities in the Sierra Nevada portion of the Hetch Hetchy Regional Water System.
