The preserved portions of the transcontinental railroad bed throughout the Promontory area have been designated as a National Historic Civil Engineering Landmark. Many have argued that the transcontinental railroad was the greatest engineering feat of the nineteenth century.

This plaque was placed by the American Society of Civil Engineers in 1969 as part of the commemorative celebration of the 100th anniversary of the completion of the world's first transcontinental railroad. It is currently located just behind the Golden Spike visitor center.
