By 2017, the old structure will be completely gone and only the new bridge will grace the bay area skyline between Oakland and Yerba Buena Island
The US Naval Base at Yerba Buena Island
in San Francisco Bay (12) and the mining town of Gunnison, Colorado (13), also offer potential lessons for contemporary pandemic influenza preparedness planning.
If the Bay Bridge had only one great silver suspension span from the Embarcadero to Yerba Buena Island
it would probably be more of a rival to the Golden Gate span.
However, the design included a pedestrian/bike path mounted on the south side of the bridge, with access to Yerba Buena Island
Thus began the process of creating, designing, and constructing the new east span from Oakland to Yerba Buena Island
, which is roughly halfway between Oakland and San Francisco.
Across from the skyscraper mountains of San Francisco's skyline and the lower-lying silhouette of Yerba Buena Island
, the East Bay shoreline is a relatively undeveloped stretch of marshlands and landfill--habitat for thousands of resident and migratory birds.
The east span is a 7.6-kilometer (4.7-mile) truss structure, extending from Yerba Buena Island
to the East Bay.

The new Bay Bridge Bike Path extension will be open this summer, allowing riders and pedestrians to travel from Oakland all the way to Yerba Buena Island
. On Thursday, Caltrans engineers will update the Toll Bridge Program Oversight Committee (TBPOC) on what remains to be done on a redesigned section of the Bay Bridge Bike Path.
The Navy owns land on Yerba Buena Island
that will be needed for the proposed construction.
The creation of Treasure Island--a herculean task that took two years (1936-37), $3,799,800, and 400 acres of shoals near Yerba Buena Island
a half-century ago-- would be financially and environmentally unthinkable in 1986.
