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.

Greenfield can be seen on the 1917 California State Automobile Association Map along LRN 2. LRN 2 is displayed to be aligned on what is now El Camino Real through the community.

The 1920 Rand McNally Highway Map of California shows El Camino Real and the Pacific Highway following LRN 2 through Greenfield.

The 1924 Rand McNally Map of California shows the California Banff Bee-Line Highway co-signed with the Pacific Highway through Greenfield.

The initial draft of the US Route System was approved by the Secretary of Agriculture during November of 1925. The US Route System within California was approved by California Highway Commission with no changes recommended by January 1926. The initial alignment of US Route 101 ("US 101") was planned to follow LRN 2 from San Francisco to San Diego via Salinas Valley. US 101 is shown on a map published in the 1926 California Highways & Public Works following LRN 2 south from San Francisco towards San Diego.

During November of 1926 the US Route System was approved by the ASSHO. US Route 101 can be seen aligned through Greenfield on the 1926 Rand McNally Junior Map of California.

The January/February 1929 California Highways & Public Works noted part of US Route 101/LRN 2 between Greenfield and King City was in the process of being widened to 30-feet.

The January/February 1933 California Highways & Public Works announced the full widening of US Route 101/LRN 2 between Greenfield and King City as part of the 1933-35 budget. The existing 15-foot-wide surface between Greenfield and King City is noted to be failing.

The July 1934 California Highways & Public Works announced the widening of US Route 101/LRN 2 between Greenfield and King City to a 36-foot-wide roadbed as being complete.

The November/December 1956 California Highways & Public Works announced the widening of US Route 101/LRN 2 to four-lane expressway standards from 1.8 miles north of the Salinas River to 2 miles south of Greenfield as being budgeted for the 1957-58 Fiscal Year. A second expressway project is listed as beginning 1 mile north of Greenfield to the Salinas River near Soledad.

The May/June 1957 California Highways & Public Works notes the expressway expansion of US Route 101/LRN 2 between Greenfield and Soledad was underway. The expressway expansion of US Route 101/LRN 2 between Greenfield and King City is noted to have been completed the previous February.

The October/November 1959 California Highways & Public Works announced the design and right-of-way acquisition of the US Route 101/LRN 2 freeway bypass of Greenfield were complete.

The November/December 1959 California Highways & Public Works announced construction of the US Route 101/LRN 2 freeway bypass of Greenfield was budgeted for the 1960-61 Fiscal Year.

The November/December 1961 California Highways & Public Works announced US Route 101/LRN 2 in Greenfield had been shifted to a new freeway bypass.
