The first permanent deck section of the San Francisco-Oakland Bay Bridge’s self-anchored suspension span was hoisted onto the bridge’s temporary support steel on Feb. 3. Caltrans says the “historic” lift marks the moment when the action on the permanent sections begins to shift from fabrication to construction of the iconic span. When construction is completed in 2013, the SAS will be the largest of its kind, at 2,047-ft-long, and it will have a single, 525-ft-tall tower. The various sections have different weights, ranging from 559 tons to 1,669 tons. Lengths also vary, ranging from 60 ft long up to 229 ft long.
