McCarthy Memorial Bridge) is the northernmost of the east--west crossings of the San Francisco Bay in California, USA . Officially named after California State Senator John F. McCarthy, it bridges Interstate 580 from Richmond on the east to San Rafael on the west . It opened in 1956, replacing ferry service by the Richmond--San Rafael Ferry Company . </P> <P> Proposals for a bridge were advanced in the 1920s, preceding the completion of the Golden Gate Bridge . In 1927, Roy O. Long of The Richmond--San Rafael Bridge, Incorporated, applied for a franchise to construct and operate a private toll bridge . The proposed 1927 Long bridge would have been a steel suspension bridge, carrying a 30 - foot - wide (9.1 m) roadway for a distance of 14,600 feet (4,500 m) at an estimated construction cost of US $12,000,000 (equivalent to $169,100,000 in 2017). The bridge would afford a maximum vertical clearance of 135 feet (41 m) with a 1,200 - foot (370 m) main span . Charles Derleth, Jr. was selected as the consulting engineer, after having served in that role for the recently completed Carquinez Bridge . The Long bridge would have spanned San Pablo Bay between Point Orient (in Contra Costa County) to just below McNear's Point (in Marin County), and Long was granted the franchise in February 1928 by the Contra Costa County Board of Supervisors . </P>
