Massive Tub Girders Will Link Bay Bridge’s Troubled Spans
Replacing the San Francisco-Oakland Bay Bridges eastern spans without further setbacks hinges on crucial milestones in the months ahead. Among them is a 2,000-ton mega-lift planned for mid-January that will open the way for the bridges controversial signature span.
Bids are due Feb. 1 for construction of the self-anchored suspension span, intended to link Yerba Buena Island and a 1.3-mile-long, segmental concrete "skyway" that stretches to Oakland. The spans cables, strung from a 510-ft-tall tower, will anchor to the bridge deck.
