Highway 1 is one of the most famous and infamous highways in California. I say infamous because this is the highway that was proposed to be a freeway offshore and has one of the highest maintenance bills for any State roadway in California. The Big Sur section is closed more than it is open in wet winters, the Malibu section is plagued by slides and has been since opening in the 1920’s. Highway 1 from US 101 at El Rio to Dana Point used to be signed as US 101 Alternate from 1935 until 1964.

Along the Pacific Coast Freeway, the only long section built. This was constructed about 1957. The other section is essentially a long ramp from I-5 in Dana Point.

Entering the McLure Tunnel. While considered by most the beginning of I-10, it doesn't begin until Lincoln Blvd, where SR-1 leaves the freeway and heads south.

Split between SR-1 and SR-2 at I-10 / Lincoln Blvd. This is one of the few places that two consecutive route numbers meet in California.
