Cypress Street Viaduct

Construction on the second phase of the project, the double-decked viaduct portion (which started from Adeline Street in the south to the MacArthur Maze in the north), began in February 1956 by contractors Grove, Wilson, Shepard and Kruge at a cost of $8.3 million, bringing the total cost of the viaduct project to $10 million.After the earthquake stopped (with no aftershock), local residents and workers began crawling into and climbing upon the shattered structure with the goal of rescuing those left alive.[6] The collapse of the upper tier onto the lower tier resulted in 42 fatalities—while this represented two-thirds of the total quake death toll of 63,[7] it was a magnitude lower than initially feared; with San Francisco and Oakland in the World Series, many would-be commuters in both cities had left work early or stayed late to watch the upcoming Game 3, and as a result traffic on the viaduct was far lighter at the time of the quake than it normally would have been.In 1997, the Nimitz Freeway was rerouted to loop around the area using a largely ground-level design with more conventional single-level viaduct.During construction of the new section of the Nimitz Freeway, a team of archaeologists made many discoveries about the people who lived in West Oakland in the 19th century.
