CALIFORNIA STATE ROUTE 170

'State Route 170' is a California State Highway in the city of Los Angeles that runs in a north-south direction. It is composed of two distinct sections. The first is the part of ''Highland Avenue'' that starts from Santa Monica Boulevard and ends at U.S. Route 101. The second portion is the northern portion of the 'Hollywood Freeway', starting at the intersection of 101 and SR-134 and continuing to its terminus at the Golden State Freeway (Interstate 5).

Route description

Although Highland Avenue starts from south of Wilshire Boulevard, it does not pick up its State Route designation until it meets Santa Monica Boulevard in Hollywood. This portion is unsigned and the only indications that it is a state highway are several reassurance shields on Highland Avenue. Before the freeway, Highland Avenue passes the Hollywood and Highland shopping center as well as the Hollywood Bowl, whereupon it goes directly onto northbound US-101.
SR-170 resumes its northbound route at the junction with the Ventura Freeway. SR-134 heads to the east and US-101 continues to the west. On the southbound side, a sign wrongly indicates "END Route 170," although this may be referring to the end of the freeway portion. Curiously, there is no interchange from 134 West to 101 South. This connector route was put on hold pending the construction of the Laurel Canyon Freeway, which never came to fruition. Motorists intending to go in that direction need to exit 134 at Cahuenga Blvd. and re-enter on 101. Likewise, there is no interchange from 101 North to 134 East (Vineland Ave. is the designated exit). This interchange is also known as the "Hollywood Split."
SR-170 then continues through the northeastern portion of the San Fernando Valley, finally merging onto northbound I-5. There is no connector route to the 5 South, however, because the angle between the two freeways is too acute. There are HOV lanes in operation 24 hours a day in each direction of this section.

History

SR-170 has another portion defined from Los Angeles International Airport to SR-90, which was supposed to become the ''La Cienega Freeway''. In fact, a portion of La Cienega Blvd. between Manchester Ave. (the former SR-42) and Rodeo Rd. was constructed to freeway standards, although it is now an expressway maintained by Los Angeles County.
SR-170 was also originally proposed to be a freeway through the Laurel Canyon section of Los Angeles along the current alignment of Laurel Canyon Boulevard, to be known as the Laurel Canyon Freeway, but this was never constructed. Had it been, it would have continued to a massive interchange of the Laurel Canyon Freeway, the 5, the Hollywood Freeway (the current 170), and the Sunland Freeway (the unconstructed SR-64).
