VIDEO: Crews construct world’s largest self-anchored suspension bridge

Screen Shot 2013-08-27 at 3.36.17 PM [1]In California, crews have been working for more than 10 years to construct the largest self-anchored suspension (SAS) bridge in the world, and Wired has shared some close-up photos of the project [2], thanks to photographer Joseph Blum, who has seen the entire construction project so far.



The 2,047-foot eastern span of San Francisco’s bay bridge [3] is supported by a single nearly 1-mile long cable connected to a 525-foot tall tower by 200 suspender ropes, according to The San Francisco-Oakland Bay Bridge Seismic Safety Projects website [4]. The bridges roadways are compiled of 14 sections, each varying in weight between 559 tons and 1,669 tons, as well as in length, from 64-feet long up to 229-feet long.

Watch the video to the right to learn more about the bridge’s components.

As Wired reported, the span is anchored in mud strata. It features giant shock-absorbing fuses beneath the road that are intended to let the bridge act a seismic neutralizer and allow emergency services to enter San Francisco after an earthquake. The bridge is expected to last 150 years.

The project currently costs $6.3 million — well above initial projections — but could have a final price tag of more than $12 billion.

To check out some of the photos of the bridge’s construction, head over to Wired to view more [2].
