This week marks the 84th anniversary of the opening of the San Francisco-Oakland Bay Bridge. The span opened Nov. 12, 1936, six months before the Golden Gate Bridge.
The bridge is the region's workhorse bridge, carrying more than a third of the traffic of all of the state-owned bridges combined.
The MTC Library recently uncovered a document that is a fun read for fans of the Bay Bridge and history.
The document was published in November 1936 by the California Department of Public Works to commemorate the opening of the Bay Bridge.
The publication has many photos and stories about the building of the span, as well as opening day ceremonies and documents President Franklin D. Roosevelt's participation in the event.
There are also some projections about the span's future that didn't quite come true: "...according to our most careful estimates, the bridge should pay for itself in about 20 years. After that it will become a FREE BRIDGE!"
