Completing the last link in the transcontinental railroad with a spike of gold was the brainchild of David Hewes, a San Francisco financier and contractor. The spike had been manufactured earlier that year especially for the event by the William T. Garratt Foundry in San Francisco. Two of the sides were engraved with the names of the railroad officers and directors. A special tie of polished California laurel was chosen to complete the line where the spike would be driven. The ceremony was originally to be held on May 8, 1869 (the date actually engraved on the spike), but it was postponed two days because of bad weather and a labor dispute that delayed the arrival of the Union Pacific side of the rail line.

On May 10, in anticipation of the ceremony, Union Pacific No. 119 and Central Pacific No. 60 (better known as the Jupiter) locomotives were drawn up face-to-face on Promontory Summit. It is unknown how many people attended the event; estimates run from as low as 500 to as many as 3,000; government and railroad officials and track workers were present to witness the event.

The golden spike was made of 17.6-karat copper-alloyed gold, and weighed 14.03 troy ounces. It was dropped into a pre-drilled hole in the laurel ceremonial last tie, and gently tapped into place with a silver ceremonial spike maul.
