Construction crews have erected twelve foot wide catwalks that connect to the San Francisco-Oakland Bay Bridge self-anchored suspension span’s tower and crews will begin to lay the nearly one mile of main cable beginning in early 2012. (Getty Images)
The bridge has been under construction since 2002 with an estimated price tag of $6.3bn and will have the world’s tallest Self-Anchored Suspension (SAS) tower once completed. (Getty Images)
When completed, the Self-Achored Suspension span (SAS) will transform the bridge’s appearance with its unique, asymmetric design. (Getty Images)
All elements of the SAS, including the tower, piers, colour and lighting, will emphasise an elegant, futuristic appearance. (Getty Images)

The SAS has been designed to be aesthetically unique as well as functional — capable of withstanding a major earthquake. (Getty Images)

During the 1989 Loma Prieta earthquake, a 50ft (15m) section of the upper deck of the eastern truss portion of the bridge collapsed onto the deck below, indirectly causing one death at the point of collapse. (Getty Images)
The original eastern span of the Bay Bridge, built in 1936, became the subject of concern after a section collapsed during the Loma Prieta earthquake in 1989. The replacement span is engineered to withstand the largest earthquake expected over a 1500 year period, and it is expected to last at least 150 years with proper maintenance. (Getty Images)
