Ferries had been around since before the Gold Rush, transporting people, animals, and goods among the various cities and villages surrounding the Bay. They were perfectly suited for such an era, a welcome innovation. In 1919, over 120,000 vehicles crossed the bay on the boats owned by Southern Pacific and other companies. By 1928, that number increased to 2.2 million! But demand continually outstripped supply, and in 1930, 9,000 of those of automobiles were stuck in Marin County, waiting to get home from the Labor Day weekend. The ferry companies had added boats and made 15 trips per hour, and even then the last of them didnít make it back to San Francisco until that Tuesday! Events like that became more common as the population of people and automobiles grew ever larger.
