The two ends of the railroad started in Sacramento, California, and Omaha, Nebraska. Workers laid track over treacherous terrain for seven years before the railroads finally met at Promontory, Utah, on May 10, 1869. A memorial marker at the site commemorates where the last railroad spike was driven into the track.
