|
The Temporary Bypass Structure, a 5000 ton, multi-span, double-deck, steel truss structure, 160 feet tall, was erected to divert Interstate 80 traffic on the existing Bay Bridge to south of the Yerba Buena Island Tunnel. The structure creates the room needed to erect a permanent structure, the YBI Transition Structure, which, when completed, will allow traffic to flow in its current alignment from the Self-Anchored Suspension span into the Yerba Buena Island tunnel.
Following the successful SFOBB Detour Tie-In Labor Day 2009 project, this temporary structure became operational on September 8, 2009.
Exactly two years earlier, the SFOBB Roll-in Labor Day 2007 project involved the roll in of 348 feet of the viaduct connecting the East Span of the Bay Bridge with the tunnel on Yerba Buena Island.
The Design/Build structure is a mixture of Concrete Box Girder, Slab, and Structural Steel Bridge. Demolition of the existing bridge connection is expected to be completed in late 2010.
