Golden Spike National Historic Site

On May 10, 1869, two railroad companies, Union Pacific and Central Pacific, joined 1,776 miles of rail at Promontory Summit, Utah Territory. This event sparked unforetold consequences still reflected in our great nation today. Golden Spike was designated as a national historic site in nonfederal ownership on April 2, 1957, and authorized for federal ownership and administration by an act of Congress on July 30, 1965.
