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).

This route is part of the California Freeway and Expressway System.

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 SR 134 West to US 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 SR 134 at Cahuenga Blvd., make a left, continue on Lankershim Blvd. and follow the signs near Universal Studios to re-enter on US 101. Likewise, there is no interchange from US 101 North to SR 134 East. Motorists intending to go in that direction needto exit US 101 at Vineland Ave., make a right, make another right on Riverside and enter the SR 134 on the left. 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 I-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 SR-170 between I-5 and the Hollywood Split interchange. As part of the I-5 improvements, construction has begun on the interchange of SR 170 and I-5 to make the current SR 170 carpool lanes connect with the proposed I-5 carpool lanes. This as well as improve traffic flow in and out of the interchange. When the I-5 improvements are completed, SR 170 carpoolers will be able to connect with the I-5 carpool lanes as well as the SR-14 carpool lanes (from the I-5) without merging into regular lanes.

History

SR 170 was originally supposed to run from the I-5 interchange to I-405 near the Los Angeles International Airport as the Laurel Canyon Freeway under the Laurel Canyon Boulevard, Crescent Heights Boulevard and La Cienega Boulevard alignments of today. In fact, a portion of La Cienega Blvd. alignment between Manchester Avenue and Rodeo Road was constructed to freeway standards, although it is now an expressway maintained by Los Angeles County.
