State Route 170 is a 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
SR 170 begins its northbound route at the junction with the Ventura Freeway, continuing the freeway northwards. US 101 leaves the freeway, merging onto the Ventura Freeway and heads west. SR 134 continues the Ventura Freeway, heading east. On the southbound side, a sign indicates "END Route 170". 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 must exit SR 134 at Cahuenga Boulevard, 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 must exit US 101 at Vineland Ave., make a right, make another right on Riverside Dr. and enter 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 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. There is a direct connection from the northbound SR-170 HOV lanes onto the northbound I-5 HOV lanes, as well as from the southbound I-5 HOV lanes onto the southbound SR-170 HOV lanes. This makes it possible to connect with the I-5 HOV lanes as well as the SR-14 HOV lanes (from the I-5) without merging into regular lanes.
SR 170 is part of the California Freeway and Expressway System,[2] and are part of the National Highway System,[3] a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration.[4]
As of 2018, Caltrans is planning to add soundwalls to SR-170 in both directions between Sherman Way and the Hollywood Split. There are currently some neighborhoods located near the freeway, which cause noise pollution. Now that soundwalls are in place, it can reduce the noise and reduces smog.
History
The highway north of the Ventura Freeway to the Golden State Freeway was completed in 1968.[5]
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, much of La Cienega Blvd. between Manchester Avenue and Venice Blvd. was constructed to freeway standards, with several grade-separated interchanges, although it is now an expressway maintained by Los Angeles County.
California's legislature has relinquished state control of the segment of SR 170 along Highland Avenue, and thus that portion is now maintained by the City of Los Angeles.[6]
