From California: Guide to the Golden State:
"The SAN FRANCISCO-OAKLAND BAY BRIDGE, San Francisco approach from Bryant and 5th Sts., completed in I937, was designed and constructed by the Department of Public Works of the State of California. Spanning the broad waters of the East and West Bay, this magnificent steel and concrete bridge serves as a giant traffic artery between San Francisco and the neighboring towns in Alameda County. It stretches its lofty spans from the anchorage in San Francisco to Yerba Buena Island, and continues at an oblique angle to the eastern approaches of Berkeley and Oakland. The bridge proper, including the island crossing, is approximately 4.5 miles long, and more than 8 miles in length from the ends of the east and west approaches.
The bridge is a double-deck structure, with six traffic lanes for
automobiles on the upper level, and three truck lanes and two interur-
ban tracks on the deck below. The western section of the bridge, 216
feet above the water, consists of two suspension spans, fastened midway between San Francisco and Yerba Buena to a steel and concrete anchor, the latter rising 502 feet from the rock floor of the bay. The two center spans on each side of the anchorage are 2,310 feet in length. The bridge is illuminated at night with strings of yellow sodium vapor lights, the brilliant rays of which can penetrate the thickest fog."
Now days the top deck is used for traffic going into San Francisco. The lower deck is for traffic going to Oakland. Everything else seems to be the same.
