Old US 101 in Buellton

[Max Rockatansky]

The original alignment of US Route 101 in Buellton can be found on Avenue of the Flags.  Avenue of the Flags originally carried a two lane configuration of US Route 101 which was expanded to a four lane expressway during 1948.  The two lane 1948 Santa Ynez Bridge would later become a choke point on US Route 101 as it was continually expanded through the 1950s and 1960s.  Buellton and Avenue of the Flags were finally bypassed when US Route 101 moved to a freeway in 1965.  Featured on the cover photo of this blog is US Route 101 on Avenue of the Flags in 1949 facing towards Pea Soup Andersen's.

Buellton is unusual in that the E-W state highway intersecting US 101 -- originally right at the original Anderson's Pea Soup restaurant -- started off as SSR 150, but when DOH (D5) decided to eliminate SSR signage from the convoluted LRN 80 route through Santa Barbara residential neighborhoods circa '59, the western portion of LRN 80, including the westernmost of the two LRN 80 spur connectors to US 101 along San Marcos Pass Road, was re-designated as SSR 154, complete with the then-latest-and-greatest black-on-white reflectorized shields; originally that signed route shifted from LRN 80 to LRN 149 east of Solvang before entering Buellton and continuing on west to Lompoc and an end at the SP depot in the town of Surf.  With the '64 renumbering, new CA 154 was rerouted to continue NW along former LRN 80 via Los Olivos and then a terminus at US 101; from the former LRN 80/149 junction west through Buellton the route was signed as CA 246 -- one of the first 200+ routes to see signage, along with 237, 238, and 299*.  So within a 5-year period that route carried 3 different signed numbers; an unusual situation save for the "sign-salad" multiplexes targeted by the renumbering effort.

*Most of the remaining "200" series highways with traversable mileage were signed during the 1967-69 "if we own it we'll sign it" period.

Was Jonata Park Road old US-101? The trajectory suggests that it might be since it continue north beyond Avenue of the Flags and the pavement points to US-101 at the north end.

Yes, up to that curve you are seeing.  I ran across when they became an expressway but I really didn't want to go outside the scope Buellton.  I'm actually struggling to think what blog I put that corridor into?  One thought tells me CA 135, another was the Buellton blog and third was maybe doing something Zaca Canyon.  Trouble with Zaca Canyon is that the alignment history just isn't all that exciting as the cities and towns.
