Who built the transcontinental railroad?
The Union Pacific Railroad and The Central Pacific Railroad Companies were formed to build the railroad. Many of the CPR workers working east from California were Chinese-Americans and many of the UPR workers building west from Nebraska were Irish immigrants.
The transcontinental railroad was built by the Union Pacific Railroad going west from Omaha, Nebraska. They built their part of the railroad to Promontory, Utah. The Central Pacific Railroad built the other part of the transcontinental railroad starting in Sacramento, California and built east meeting the Union Pacific Railroad.
this is because the transcontinental railroad would connect the east and west. This would encourage people to settle west and develop the land there. The government lent the Union Pacific and the Central Pacific railroad companies millions of dollars to build the transcontinental railroad. Hope this helped they could also make profits of the railroad
