Bay Bridge – Engineering
Latest SF Bay Area Bay Bridge – Engineering
At long last, the new, $6.4 billion eastern span of the San Francisco-Oakland Bay Bridge opened to traffic Monday evening.
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.
That’s the question as we draw closer to when the new eastern span of the Bay Bridge is supposed to open. Bad bolts have dealt a heavy blow to public trust of the new bridge. The partial collapse of the eastern span in 1989 led to construction of the new bridge with its “lifeline” designation – meaning it is designed to quickly reopen following a major earthquake.
The self-anchored suspension tower may be what makes the new Bay Bridge tower iconic, but a hidden aspect of the structure actually acts as the nerve center of the new eastern span. The hollow center of the new Bay Bridge is essentially a corridor that runs 1.7 miles from the middle of the bay all the way to Oakland.
At Sacramento-based MCM Construction, bridges are their business. They have worked on between 1,200 and 1,500 bridges in California alone. These days there is no bigger project than the new span of the Oakland Bay Bridge. It’s been MCM’s home away from home for the last 6 years.
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.
