The San Francisco Bay Bridge. though less famed than its colorful sister, The Golden Gate Bridge, is a spectacular structure. The span from the city to Treasure Island in the middle of the bay is a double suspension bridge with a huge concrete structure in the middle that anchors the two halves.
The span from Treasure Island to Oakland is a soon to be replaced cantilever.
