The American Bridge/Fluor joint venture (ABFJV) began construction on the SAS portion of the bridge in 2006. The bridge officially opened to traffic on the eve of September 2, 2013.
The SAS, together with the Skyway and Oakland Touchdown, completed the east span of the Bay Bridge. Initial construction activities included logistics planning and long-range procurement. A 400-foot long, 1,700-metric-ton capacity shear leg crane barge was constructed to lift the massive segments of the deck and tower. Bridge components are being fabricated in the United States, Europe, and Asia. A secondary office was established in Shanghai, People's Republic of China, to oversee production of the main structural steel fabrication and supply.
ABFJV erected a falsework structure to support the new road deck. Bridge components shipped via eight shipments, arriving every two months from China. Road deck segments were lifted from the barges onto the falsework by the shear leg crane barge, with the road deck in-place after 28 lifts. The 160-meter tall single tower from which the bridge is suspended was completed concurrently. After installing the 800-mm diameter main cable and suspender cables, the deck weight was transferred from the temporary falsework to the main cable.
