Benicia–Martinez Bridge, Road and railway bridges in Martinez, United States
The Benicia-Martinez Bridge system consists of three parallel structures spanning 2700 meters across the Carquinez Strait in Northern California.
The railway bridge, constructed in 1930, replaced the Southern Pacific Railroad ferry service, while the first road bridge opened in 1962 to eliminate automotive ferries.
The bridges represent a transition period in California transportation, marking the end of ferry services and the rise of modern infrastructure connecting Bay Area communities.
The northbound span features five lanes with electronic toll collection, while the southbound span accommodates four lanes plus a dedicated bicycle path.
The railway bridge section holds the title of longest railway bridge west of the Mississippi River, measuring 1.7 miles in length.
