Bay Bridge – Engineering
Latest SF Bay Area Bay Bridge – Engineering
The opening of the new eastern span of the Bay Bridge Monday night marks the end of a lengthy process that began shortly after a section of the old span collapsed in the Loma Prieta earthquake in 1989
Construction work is proceeding as planned on the new eastern span of the Bay Bridge and BART ridership swelled to its second-highest Saturday ever as the agency increased weekend trains to accommodate the bridge closure.
Officials say there were no problems during the first hours of construction to put finishing touches on the new eastern portion of the San Francisco-Oakland Bay Bridge.

It rises some 525 feet above the bay, blazing white against the sky. The centerpiece of a creation blending architecture and engineering in a way never done before.
The new Bay Bridge is in the same league as the White House, the Statue of Liberty and Yankee stadium. They all have one thing in common – the lighting.
SAN FRANCISCO (CBS 5) – Hundreds of workers spend their days hundreds of feet above the bay, and keeping them all safe is a huge job in itself. At any given time, 800 workers move […]
