The new San Francisco-Oakland Bay Bridge East Spans is comprised of four distinct structures, these are: a low rise post-tensioned concrete box girder near the Oakland shore; a 2.4 km long segmental concrete box girder; a self-anchored suspension signature span; and a post-tensioned concrete box girder that connects to the east portal of the Yerba Buena Island tunnel.
The Self Anchored Suspension Bridge consists of dual box girders suspended from cables which are supported on single 160-m tower located off of the eastern shore of the Yerba Buena Island. The SAS spans 565 m between the piers E2 and W2, with a 385m main span, over the navigational channel, and a 180 m back span. The new Bridge was open to traffic in 2013.
