Part 1; the history of US Route 99 in McFarland and Delano
Both McFarland and Delano are located on what was the Southern Pacific Railroad (presently Union Pacific Railroad) in southern San Joaquin Valley. When the Southern Pacific was building it's line through San Joaquin Valley towards Tehachapi Pass it plotted Delano as one of it's sidings. Delano was formally plotted out on July 14th, 1873 when it was at the temporary southern terminus of the Southern Pacific Railroad line through San Joaquin Valley. Delano was named in honor of then U.S. Secretary of the Interior Columbus Delano. Post Office Service was established in Delano in 1874 and it would incorporate as a City on April 13th, 1915. Delano can be seen on the 1876 Holt Map of California and Nevada along the Southern Pacific Railroad.
McFarland was plotted out in 1907 when James Boyd-McFarland purchased Hunt's Siding which was located on the western flank of the Southern Pacific Railroad. Post Office Service in McFarland would be established in 1908 but a town site would not be formally plotted until 1909. McFarland would incorporate as a City on July 18th, 1957.
LRN 4 is reported in the October 1926 California Highways & Public Works as having been recently paved through Delano via 20 foot wide concrete slabs.
The May 1936 California Highways & Public Works notates that construction of the Delano Underpass was funded via a Federal Aid program and the state gas tax.
The August 1936 California Highways & Public Works discusses the opening of the "Delano Underpass" realignment of US 99/LRN 4 in Delano. The Delano Underpass is described as a 0.97 mile realignment of High Street which carried four ten foot lanes of US 99/LRN 4. The previous overpass alignment of US 99/LRN 4 via High Street was considered one of the most dangerous in San Joaquin Valley.
