CR N1 is part of the State Scenic Highway System in Los Angeles County.

Major landmarks along the route include Pepperdine University on the west side of the road at Pacific Coast Highway.

Soka University was located at King Gillette Ranch along this road near the intersection of Mullholland Highway.

Plans to expand were stopped and the land sold to the National Park Service in 2005.

The main entrance Malibu Creek State Park is just south of that same intersection.

CR N2 begins at the junction of State Route 138 at Quail Lake and heads south along the old Ridge Route (as Old Ridge Route Road) to Sandberg, and then southeast, parallel to the San Andreas Fault along Pine Canyon Road to Lake Hughes Road in Lake Hughes.

From there, it continues straight ahead initially southeast along the San Andreas Fault on Lake Elizabeth Road and then, leaving the fault it continues east on Lake Elizabeth Road to 10th Street West / Tierra Subida Avenue in Palmdale.

It was originally surveyed in 1913 and constructed between 1932 and 1941 to access Southern California Edison transmission lines that cross the San Gabriel Mountains between the Antelope Valley and the Los Angeles Basin.

Hawthorne Boulevard is very distinctive through Lawndale and part of Hawthorne because it is very wide with business parking in the center between the northbound and southbound lanes; the parking area was once part of a Pacific Electric right-of-way.

Landmarks along Hawthorne Boulevard include Point Vicente Lighthouse park and Point Vicente Interpretive Center, Palos Verdes Peninsula High School, South Coast Botanic Garden, Del Amo Fashion Center, South Bay Galleria, Hawthorne Plaza, and a Metro C Line station at Interstate 105.

Only a quarter mile of the route is in Orange County (between Alondra Boulevard and SR 39).
