Oakland Assembly was a former Chevrolet manufacturing facility that later became a General Motors automobile plant located in Elmhurst, Oakland, California. It was the first automobile plant established in Northern California to build Chevrolet vehicles. In 1916, Chevrolet opened the auto industry's first West Coast assembly plant in Oakland. Production of the Chevrolet Series 490 began on Sept. 23, 1916, while World War I was taking place (28 July 1914 – 11 November 1918).
