In 1963, US 6 was shortened to Bishop and was resigned as SR-14 from Inyokern to Newhall Pass. The only segment of old US 6 not to be signed as SR-14 was the segment of Sierra Highway from Solemint Junction to Red Rover Mine Road near Acton. Please make a note of it. The following photo is a milepost on Sierra Highway at Friendly Valley Parkway. The mileage is not correct.
Mileage increases north and east.
This milepost shows 30 miles to the end of the highway. CA 14 ends at I-5. Caltrans had planned on completing the highway from I-5 to the Pacific Coast Highway near Sunset Blvd. This is the reason for the error. Today Mileage sign on US 6 leaving Bishop, CA Current Mile 0 for US 6.
