BAY AREA NOW HOME TO WORLD’S LARGEST SELF-ANCHORED SUSPENSION SPAN

The dream of building the world’s largest Self-Anchored Suspension Span (SAS) is now a reality. The weight of the bridge is supported by the single, nearly 1-mile long main cable. Workers have successfully completed load transfer, which shifted the bridge’s weight from the temporary supports to the main cable. The process took just under three months.

SPOTLIGHT SHINES ON BAY BRIDGE DESIGN

From the single, elegant tower to the unique asymmetric shape of the Self-Anchored Suspension Span, the new Bay Bridge is a testament to innovative design and aesthetics. On November 29, the second installment of the free Joseph Nicoletti Lecture Series focused on the aesthetics of the new East Span and how the design of the forthcoming engineering icon came to be. Clive Endress (Senior Landscape Architect), Michael Fitzpatrick (Bridge Architect from T.Y. Lin International) and Donald MacDonald (of Donald MacDonald Architects) discussed the innovative look of California’s largest public works project.

Exclusive Look Inside the SAS Anchorage

Take a rare look deep inside the anchorage of the world’s largest self-anchored suspension span for never before seen images of how we are building the Bay Bridge’s new East Span. Unlike a transition suspension bridge, a self-anchored suspension span’s anchorage is hidden inside the road-decks, which is an amazing combination of engineering and design.

The War on Corrosion

Watch how the Bay Bridge battles the ravages of corrosion, from the top of the 525-foot-tall SAS tower to inside the concrete decks of the 1.2-mile-long Skyway.

 

Watch how we’re building the Yerba Buena Island Transition Structure, including a massive concrete pour and how we made that concrete stronger with steel tendons.

UPDATED NOTICE TO BOATERS

Due to construction on the Bay Bridge, boaters are prohibited from passing beneath the span just east of Yerba Buena Island. Read the Updated Notice to Boaters

YERBA BUENA ISLAND TRANSITION STRUCTURE UPDATE

Crews have completed the post-tensioning process on the Yerba Buena Island Transition Structure (YBITS), bolstering the strength of the existing concrete. Workers will spend the next few weeks pouring the last of the concrete and removing the temporary steel structure built to support the span during construction. YBITS will connect the Self-Anchored Suspension Span (SAS) to Yerba Buena Island (YBI) and transition the new East Span’s side-by-side road decks to the upper and lower decks of the YBI Tunnel and West Span.

OAKLAND TOUCHDOWN CONSTRUCTION UPDATE

Crews began building the rest of the Oakland Touchdown’s (OTD) eastbound deck in June; the westbound deck and approximately half of the eastbound deck were completed in June 2010. Detours near the Toll Plaza have shifted traffic away from construction, allowing workers to finish building eastbound deck. Find out more>
