Pre 1964 Signage History
Until July 1, 1964, the following route was signed as US 399:
- Present-day Route 33 between US 101 [LRN 2] in Ventura and Route 166
(LRN 57) 7 mi N of Ventucopa. This segment was LRN 138, defined in 1933.
- Present-day Route 33/Route 166 (previously cosigned as US 399/Route 166) between 7 mi N of Ventucopa and Maricopa. This segment was LRN 57,
defined in 1919.
- Present-day Route 33 between Maricoa and Taft (previously cosigned as
US 399/Route 33). This was LRN 138, defined in 1933.
- Present-day Route 119 between Taft and US 99 (present-day Route 99).
This was LRN 140, defined in 1933.
Signage of the route as US 399 dates back to around 1935. Note that, as
of 1936, US 399 actually continue north cosigned with US 99 to end at US 466. This portion of US 399 was later relegated to Business Loop status in
1962, and became Business Route 99/Route 204 in 1964. However, the portion of former
US 399 south of Brundage Lane (current parallel street to Route 58, the
replacement for US 466) was removed from the state route in 1978; only the
portion of former US 99 on Union Avenue from Golden State Avenue/Sumner
Street south to Route 58 remains in the state system as Route 204. All of
the route remains part of Business Route 99.
