Park Histories | Neighborhood Parks Council. Glen Park Merchants Association. Seismic Innovations & Enhancements on the East Span | Bay Bridge Info. The design, engineering and construction teams have met the challenge of making the Bay Bridge seismically resilient with cutting-edge innovations and enhancements—some never before used in bridge building—that are transforming the bridge into a state-of-the-art engineering icon.
The first section crews completed was the Skyway, which also includes some of the most amazing seismic innovations. To build the Skyway’s foundations, 160 rebar and concrete-filled steel piles were driven up to 300 feet below the water’s surface to anchor into stable soils. The piles were driven into the soil at an angle, through a process called “battering,” to create greater stability. This method has been used to create secure foundations for oil rigs for more than two decades, but has not been used in bridge construction of this scale. Hinge pipe beams are not the only innovation in the SAS. Mission Artists United. Glen Park Association News. SanFranciscoShop. Bernal Bucks.
