The San Leandro Bay Bridge, better known as the Bay Farm Island Bridge, is a single-leaf bascule drawbridge spanning the San Leandro Channel, the inlet of San Leandro Bay within the San Francisco Bay Area, California, United States. It carries California State Route 61 and links the main island of Alameda with Bay Farm Island within the city of Alameda. The present bridge was completed in 1953; it is paralleled by a second bridge (completed in 1995) devoted to pedestrian and bicycle traffic, the Bay Farm Island Bicycle Bridge.
The Bay Farm Island Bridge is one of the four bridges and two tunnels linking Alameda Island with the mainland. It is the longest bridge of the four.
