Pacific Bridge Company. Pacific Bridge Company was a large engineering and construction company. During World War II, Pacific Bridge Company of Alameda, California was selected to build US Navy Auxiliary Repair Docks (ARD) a type of Auxiliary floating drydock and Type B ship barges.

History
The Pacific Bridge Company was founded by William Henry Gorrill in 1869. In 1942 The Pacific Bridge Company was chosen to build ships, because of their reputation and skills, particularly welding. Since the coastal shipyards were busy building large vessels for the war effort, such as aircraft carriers, battleships, cruisers and destroyers, there was no alternative but to use other builders, like Bridge builders for the production of small and medium ships. Pacific Bridge Company built the first nine N3-S-A1, Type N3 ship cargo ship sent to Britain in 1943. The type N3 ships were a Maritime Commission small coastal cargo ship designed to meet urgent World War II shipping needs. Two of the N3 ships were completed and ready in a record-breaking 22 days, A crew of 480 men worked on the ship. The SS Samuel Very was one of these ships. Two N3 ships were built at the same time in the two drydocks at the Alameda Shipyard. The Alameda Shipyard had two traveling cranes to move parts.

Henry J. Kaiser's had the Pacific Bridge Company join as one of Kaiser's "Group of Six" construction companies that help build the Hoover Dam, due to Pacific Bridge's expertise. Pacific Bridge also brought its capital into the large project The shipbuilding yard was on the Oakland Alameda estuary. Some residential homes near Clement Avenue and Chestnut Street were purchased and taken down or moved to be part of the Emergency Shipbuilding Program. The Pacific Bridge Company was a contractor to the US Navy to build the ships. The shipyard was to the West of the General Engineering & Dry Dock Company. The land for the shipyard was purchased by the Navy from 24 March to 7 July 1942. The Pacific Bridge Company Oakland Alameda yard discontinued shipbuilding after World War 2, continued manufacturing until 1969. In 1969 the yard was sold for redevelopment and today is the Alameda Marina. The Alameda Marina also has a commercial shipyard, ship maintenance facilities, industrial space, storage, and office buildings. Part of the shipyard became the Naval and Marine Corps Reserve Center in 1949. The Site had several training buildings that provided training on ship systems. 
 On January 21, 2016 demolition started of the Pacific Bridge Company workshop building on Clement Ave. The land will be used for a new condominium complex.

Before ship building, Pacific Bridge Company built bridges in both the San Francisco Bay Area and Portland, Oregon. Pacific Bridge Company built 10 bridges over the Willamette River near Portland. To provide stone for project Pacific Bridge Company purchased The McBain Stone Quarry from the estate of James McBain, in Klickitat County, Washington near the Klickitat River in 1922.
