The record-breaking SAS is the signature span of the eastern part of the new San Francisco-Oakland Bay Bridge in California, USA.
The fluorescent lights will be used construction of the SAS and its main cable at night and in heavy fog. They give an idea of how the SAS will be lit by its permanent lights when the bridge opens in late 2013. The lights were previously used during construction of the Alfred Zampa Memorial Bridge, also known as the new Carquinez Bridge.
The SAS’s single, nearly 1.6km-long cable will be anchored into the east end of the roadway, and will travel up and over the single tower to wrap around the west end before travelling back up and over the tower to anchor back into the east end.

Lights give preview of Bay Bridge skyline
Construction lights strung along the orange catwalks for San Francisco’s new self-anchored suspension span (SAS) were lit for the first time earlier this week, giving a preview of how the bridge will appear when complete.
