The original CA 14

[Max Rockatansky]

The original California State Route 14 was one of the initial Sign State Routes defined during August 1934 and was located in the Los Angeles Metropolitan area.  The original California State Route 14 began at California State Route 3 (later US Route 101A) near Hermosa Beach and ended at California State Route 18 at Santa Ana Canyon.  The early freeway segments of California State Route 14 east of Anaheim would be multiplexed with US Route 91 and California State Route 18 during the 1950s.  California State Route 14 would ultimately be replaced by California State Route 91 in 1964.  The original California State Route 14 is associated with the history of the Gardena Freeway, Artesia Freeway and Riverside Freeway.  California State Route 14 can be seen on Artesia Boulevard approaching California State Route 19 at Lakewood Boulevard during 1953 as the blog cover photo.

And later CA-14 became reused for the section that originally was signed US-6.

CA-14 on the alignments that later became US-91 and CA-91 are one of the rare cases where the route started out as a state route then US Route and state route again.

Kind of, nothing west of the Santa Ana Freeway along current CA 91 was part of US 91.

More accurately, would the portion of road that was originally Route 18, then became US 91/Route 18, then solely US 91, then Route 91 fit what bing101 was thinking of?  (today's Route 91 between Orangethorpe Avenue and Riverside)

Yes, but I had more in mind the original corridor of 14.  Granted, 18 and US 91 did both also multiplex the eastern half of 14 when the Houston Expressway was built.

One part of this is really odd as to how long the gap of even a surface street east of Normandie existed.  From the maps, it appears that the state highway resumed around Alameda Street.  One can surmise that perhaps traffic was directed to follow 190th/Victoria towards Dominguez Junction as a temproray detour until the state highway was completed.
