Self-Anchored Suspension Bridge (SAS)

With construction started in May 2006 and an anticipated completion in late 2013; the Self-Anchored Suspension (SAS) Bridge will be the longest single-tower, self-anchored suspension bridge in the world. The 2.2 mile East Span of the bridge includes two main sections: a Self-Anchored Suspension structure with a single 525-foot-tall steel tower and a 1.2 mile long elevated Skyway viaduct descending towards Oakland. One continuous main cable, anchored in the eastern section of the SAS, is carried over the single tower, then extends down and loops around the two western decks. Anchoring the main cable within the deck itself puts the span into compression and enables it to remain standing.

The SAS contract is the largest public works contract in California’s history.
