Well, I can't believe it. There is finally evidence of the I-5 corridor fast chargers from the 2014 CEC grant being installed. The first one has popped up in PlugShare at Santa Nella Village, just north of the I-5 CA 152 interchange at the Best Western Andersen's Inn. It is listed as a single CHAdeMO charger. Unknown model and power output.

Just for reference, these are the other expected locations from that grant:
From Santa Nella Village:
74 miles to Coalinga (@ 198/I-5)
56 miles to Lost Hills (@ 46/I-5)
61 miles to Wheeler Ridge (across I-5 from Tejon Ranch Tesla Supercharger)
48 miles to Valencia
There is also supposed to be an additional unit in Lebec between Wheeler Ridge and Valencia. IIRC, it should be at the Holiday Inn Express & Suites Frazier Park at I-5 and Frazier Mountain Park Road. However, it's only 15 miles up the hill from the Outlets at Tejon in Wheeler Ridge.
