Location

The Benicia–Martinez Bridge refers to three parallel bridges which cross the Carquinez Strait just west of Suisun Bay in California. The spans link Benicia on the north side with Martinez on the south. A 1962 truss bridge, officially the George Miller Jr., Memorial Bridge after California state legislator George Miller Jr., carries southbound Interstate 680 traffic, bicycles, and pedestrians. A 2007 segmental bridge, officially the Congressman George Miller Benicia–Martinez Bridge after U.S. Congressman George Miller III, carries northbound Interstate 680 traffic. The middle span is a 1930 vertical-lift railroad drawbridge that carries Union Pacific and BNSF freight trains, as well as Amtrak passenger trains.
