Part 1; the history of California State Route 39 on Grand Avenue through Knott's Berry Farm
Long before Knott's Berry Farm was a theme park it was a rural farm on the outskirts of Buena Park in western Orange County operated by Walter Knott. During the 1920s Knott and his family began to nurse abandoned berry plants back to health along Grand Avenue. The Knott's began to serve pies, berries and berry preserves along Grand Avenue during the latter part of the 1920s. In 1932 the Knott's began to introduce the Boysenberry after a visit Rudolph Boysen's farm in nearby Anaheim. The introduction the Boysenberry at Knott's Berry Farm was a hit which saw business at the pie stand along Grand Avenue begin to take off.
During 1933 the State Legislature removed the barriers preventing the Division of Highways from maintaining roads in incorporated as cities. This change led to a significant amount of highway mileage being added to the State inventory during 1933. Grand Avenue was added to the State Highway System as part of Legislative Route Number 171 (LRN 171) which was defined as:
"LRN 60 near Huntington Beach to LRN 2 (US Route 101) to Whittier"
The initial run of Sign State Routes were announced in the August 1934 California Highways & Public Works. California State Route 39 (CA 39) with the following definition:
