Richmond–San Rafael Bridge 4.65

The Richmond–San Rafael 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.HistoryEarly proposalsProposals 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 30ft roadway for a distance of at an estimated construction cost of 12000000. The bridge would afford a maximum vertical clearance of with a 1200ft 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.
