Oakland Bay Bridge Deck and Tower

摘要

In 1989 an earthquake caused a span of the San Francisco Oakland Bay Bridge to collapse, triggering the State of California to replace the bridge between Yerba Buena Island and Oakland. The signature span for the replacement bridge will be the world's largest Self-Anchored Suspension Bridge (SAS) once completed in 2013. During construction of the $1.8-billion new bridge, the deck needed to be supported on temporary structures until the cable was installed and the deck weight transferred to the cable.
