The Oakland-San Francisco Bay Bridge opened, resulting in an almost instantaneous decline in ferry service. Overnight the Ferry Building’s and the nearby pier’s raison d’être became obsolete. Simultaneously there became a greater reliance on trucking as an important mode of goods distribution and shipping. The pier sheds’ internal column grids impeded truck maneuvering, and the narrow pier aprons, designed specifically to accommodate trains, did not work well for trucks. This corresponded to periods of labor unrest, much of it focused on the Waterfront, the Port and its operations. It was here in San Francisco that important Labor Movement figures such as Harry Bridges emerged.
