Union Iron Works Co.

[After years as the premiere producer of mining, railroad, agricultural and locomotive machinery in California, Union Iron Works entered the shipbuilding business and relocated to Potrero Point, where its shipyards still exist. Under the Scott brothers, it became the largest shipbuilding plant on the Pacific Coast, but the plant was in decline when it was bought by Bethlehem Steel. Under the auspices of the Port of San Francisco, Todd Shipyards of Oakland ran the facility in the 1980s, followed by Southwest Marine in the 1990s. Union Iron Works Historic District is now part of Pier 70, a Port of San Francisco site identified as a future National Historic District due to over 150-years of continuous operations in ship building and repair, and its role in the industrialization of the Western United States, war efforts and architectural and engineering feats.]
