It went on the be called the Great Earthquake of '89. The quake killed 62 people and injured 3,757. The highest number of deaths, 42, occurred in Oakland because of the Cypress Street Viaduct collapse on the Nimitz Freeway, when the upper level of a double-deck portion of the freeway collapsed, crushing the cars on the lower deck.
It is here that an interesting ghost story has emerged. People riding on the lower level of the bridge now report hearing someone tapping on their windows. It always happens at night and some people report seeing a man, some claim he appears to be headless, moving along in the darkness. He appears to be tapping on the windows trying to catch a ride off of the bridge.
