A US$250,000 firework display will mark today’s official opening of the Carquinez suspension bridge in California. The three span, 1055m bridge crosses the Carquinez Strait navigation channel in San Francisco Bay. The structure – which is also called the Alfred Zampa Memorial Bridge after a famed local bridge worker – replaces an existing westbound crossing built in 1927. Contractors for the US$200 million project were a joint venture of FCI Constructors and Cleveland Bridge California.
