The term last spike has been used to refer to one driven at the usually ceremonial completion of any new railroad construction projects, particularly those in which construction is undertaken from two disparate origins towards a meeting point . The spike is now displayed in the Cantor Arts Center at Stanford University . </P> <P> 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 . </P>
