Las Vegans claimed to be the originators of this all-weather route between Los Angeles and Salt Lake City. From the beginning, the Arrowhead Trail was a "grassroots" effort including promotion by the various Chambers of Commerce and volunteer construction by local citizens. However, it was Charles H. Bigelow, from Los Angeles, who gave it great publicity. During 1915 and 1916 he drove the entire route many times in his Twin-Six Packard "Cactus Kate."

The trail, as seen behind you, was built in 1915 and completed the section between St. Thomas and Las Vegas. In its day it denoted a milestone of progress.
