Benicia- Martinez Bridge

The Benicia–Martinez Bridge refers to three parallel bridges which cross the Carquinez Strait just west of Suisun Bay; the spans link Benicia, California on the north side with Martinez, California on the south. The two automobile bridges are referred to collectively as "The Benicia Bridge".

The 1.2-mile (1.9 km) deck truss bridge opened in 1962 to replace the last automotive ferry service in the San Francisco Bay Area. The 1962 bridge has seven 528-foot (161 m) spans and 138 feet (42 m) of vertical clearance, now carrying four lanes of southbound traffic, as well as a path for pedestrians and bicyclists.[1] A 1.7-mile (2.7 km) bridge was built alongside and opened on August 25, 2007 with five lanes of northbound traffic. The cost of the 1962 span was US$25 million and US$1.3 billion for the 2007 span. The bridge is part of Interstate 680, major transportation link, and connects other heavily traveled freeways.

Between the two vehicle bridges is a Union Pacific Railroad bridge, the first bridge at this location, built between April 1929 and October 1930 by Southern Pacific. It is used by Union Pacific and BNSF (trackage rights) freight trains and 36 scheduled Amtrak passenger trains each weekday. Passenger trains include the long-distance trains California Zephyr and Coast Starlight and short-haul Capitol Corridor trains.
