Golden Spike National Historic Site, Utah

The point at which the eastbound and westbound tracks for the first transcontinental railroad met. A visitors center has been built here by the National Park Service, at this remote site, at the northeastern edge of the Great Salt Lake. Initially, the Union Pacific, building the westbound track from Omaha, and the Central Pacific, going east from California, refused to let their tracks meet, each wanting to have more of the territory under their jurisdiction. As a result, over 200 miles of parallel grading was completed before Congress intervened and set the meeting point at Promontory Summit. On May 10, 1869 the tracks met and four golden spikes were ceremonially driven into the last tie laid (the golden spikes were quickly removed for safe-keeping, though one has been missing ever since).
