Butterfield Overland Mail in California

The Butterfield Overland Mail in California was created by the United States Congress on March 3, 1857, and operated until June 30, 1861. Subsequently, other stage lines operated along the Butterfield Overland Mail in route in Alta California until the Southern Pacific Railroad arrived in Yuma, Arizona in 1877.

The route lasted from 1857 to 1861 and became one of the most important roads in the early settlement and development of California.^{[citation needed]}
