Part 1; the history of US Route 101 in Greenfield
During 1902 the California Home Extension Association purchased 4,000 acres of land about the Southern Pacific Railroad in Salinas Valley at what had been Rancho Arroyo Seco. The land was put to sale in Los Angeles during 1905 which led to the plotting of a town which was originally to known as "Clark City" in honor of then California Home Extension Association founder John S. Clark. Ultimately the town site was named "Greenfield" in honor of then California Home Extension Association President Edward Greenfield.
Salinas Valley was ultimately part of the American El Camino Real which began being signed as an Auto Trail starting in 1906. The era of State Highway Maintenance through Salinas Valley would ultimately begin with the 1909 First State Highway Bond Act which was approved by voters in 1910. One of the highways approved through the 1909 First State Highway Bond Act was a 481.8-mile highway originating at the City Limits of San Francisco which terminated in San Diego. This highway would ultimately come to be known in time as Legislative Route Number 2 ("LRN 2"). Within Salinas Valley much of LRN 2 would follow the existing corridor along the frontage roads of the Southern Pacific Railroad which included the community of Greenfield.
The July 1914 California Highway Bulletin notes surveys for the location of LRN 2 from Greenfield to Camphora were complete. LRN 2 between Greenfield and King City had been laid out as a 15-foot-wide highway during October 1912.
