at promontory point utah where the central pacific and union pacific
Promontory, Utah By the summer of 1868, the Central Pacific (CP) had completed the first rail route through the Sierra Nevada mountains, and was now moving down towards the Interior Plains and the Union Pacific (UP) line. More than 4,000 workers, of whom two thirds were Chinese, had laid more than 100 mi (160 km) of track at altitudes above 7,000 ft (2,100 m). In May 1869, the railheads of the Union Pacific and the Central Pacific railroads finally met at Promontory Summit, Utah Territory.[3] A specially-chosen Chinese and Irish crew had taken only 12 hours to lay the final 10 mi (16 km) of track in time for the ceremony.[4]
