State Route 118 (SR 118) is astate highway in theU.S. state ofCalifornia that runs west to east throughVentura andLos Angeles counties. It travels fromState Route 126 at the eastern edge ofVentura immediately northwest ofSaticoy, then through Saticoy, in Ventura County east toInterstate 210 nearLake View Terrace inLos Angeles. SR 118 crosses theSanta Susana Pass and the northern rim of theSan Fernando Valley along its route.
SR 118 has two distinguishable sections, which connect at the intersection withState Route 23. The western section of SR 118 goes through the more rural areas ofVentura County. SR 118 begins at an intersection withSR 126 inVentura as Wells Road and heads southeast, crossing theSanta Clara River as Los Angeles Avenue and intersectingSR 232 in unincorporated Ventura County. The highway continues southeast before intersecting Santa Clara Avenue, where SR 118/Los Angeles Avenue turns east and passes north ofCamarillo. In the community ofSomis, the highway intersectsSR 34. The road continues intoMoorpark, where it intersects SR 23 and runs concurrently with that road. After passing Spring Road, the SR 23/SR 118 concurrency continues as New Los Angeles Avenue to a freeway interchange, where SR 118 heads north, and SR 23 heads south.[2]
The eastern section is an urban freeway that starts in the cities of Moorpark andSimi Valley, and ends inLos Angeles. The SR 118 freeway initially travels north, but quickly turns east, passing nearMoorpark College, before entering the Simi Valley city limits. SR 118 continues through Simi Valley before entering Corriganville Regional Park and crossing into Los Angeles County and the Los Angeles city limits.[2] The freeway has an HOV lane between here andInterstate 5. In Los Angeles, SR 118 passes throughSanta Susana Pass State Historic Park before passing throughChatsworth and interchanging withSR 27. SR 118 subsequently goes throughPorter Ranch andGranada Hills before intersecting withI-405 and I-5. Following this, SR 118 goes throughPacoima before terminating at an interchange with theFoothill Freeway.[3]
SR 118 is part of theCalifornia Freeway and Expressway System,[4] and is part of theNational Highway System,[5] a network of highways that are considered essential to the country's economy, defense, and mobility by theFederal Highway Administration.[6] SR 118 is eligible to be included in theState Scenic Highway System,[7] but it is not officially designated as a scenic highway by theCalifornia Department of Transportation.[8] The freeway portion of Route 118 betweenMoorpark and Lake View Terrace was originally named theSimi Valley-San Fernando Valley Freeway before it was designated as theRonald Reagan Freeway in 1994.[9] It was renamed in honor ofRonald Reagan, the 33rdGovernor of California and the 40thPresident of the United States, due to the location of hispresidential library inSimi Valley.[10]
SR 118 used to extend past I-210 onFoothill Boulevard throughSunland-Tujunga,La Crescenta andLa Cañada, then across theArroyo Seco intoPasadena, where SR 118 ran on Lincoln Avenue and Fair Oaks Avenue, ending atColorado Boulevard (US 66 Alternate). The original routing across the Arroyo Seco ran along La Cañada Verdugo Road (now Oak Grove Drive), which crossed the arroyo along the crest of Devil's Gate Dam. In 1957, the first segment of theFoothill Freeway was completed between Montana and Cañada Streets in Pasadena and Foothill Blvd and Michigan Avenue in La Cañada. SR 118 ran along this short freeway until 1974, when the current Foothill Freeway alignment over the Arroyo Seco was completed further to the south. SR 118 was then truncated to its current terminus with I-210 near San Fernando.
Before the freeway was built, the route went through Simi Valley on Los Angeles Avenue and Kuehner Drive, then crossed into the San Fernando Valley on Santa Susana Pass Road. The eastern segment used Devonshire Street through the San Fernando Valley, then cut through San Fernando along Brand and Maclay Streets before joining Foothill Boulevard in Sylmar. During the1932 Summer Olympics, it hosted part of theroad cycling event.[11] The SR 118 freeway began construction in 1968 and the last section of freeway opened in 1979. The segment of freeway between Balboa Boulevard and Tampa Avenue was one of the last freeway segments to be built in the Los Angeles area. As a result of theNorthridge earthquake in January 1994, a section of the highway between I-405 and I-210 was closed for over one month while damage to an overpass was repaired. The Porter Ranch Drive interchange is relatively new; before it was constructed, that interchange connected to a closed Winnetka Avenue and aPark and Ride lot.
Route 118 from Route 23 to Route 210 was named theSimi Valley-San Fernando Valley Freeway by Assembly Concurrent Resolution 145, Chapter 185 in 1970.[10] In December 1994, the portion of Route 118 constructed to freeway standards was renamedTheRonald Reagan Freeway.[10] The original proposal for this name was introduced by Willie Brown on August 30, 1994 and amended August 31, 1994, as State Assembly Concurrent Resolution 156, however this version of the bill died on the desk in November 1994.[12] The name was reintroduced by State Senators Lockyer, Maddy, and Wright as State Senate Resolution 7, amended and enrolled December 5, 1994.[13] Since it was neither a concurrent resolution nor a joint resolution, it was not filed with the Secretary of State. The rationale for choosing this name for State Route 118 is that the western end of the highway, at the time the bill was passed, is very close to theRonald Reagan Presidential Library.
There is an additional unconstructed segment of SR 118, defined in 1959 in theCalifornia Streets and Highways Code, extending from its current terminus with I-210 to a plannedSR 249, located within theAngeles National Forest. This appears to have been roughly planned to run primarily along Big Tujunga Canyon between Foothill Boulevard andLos Angeles County Route N3,Angeles Forest Highway, which is the current traversable routing for unconstructed SR 249.[14]
Except where prefixed with a letter,postmiles were measured on the road as it was in1964, based on the alignment that existed at the time, and do not necessarily reflect current mileage. R reflects a realignment in the route since then, M indicates a second realignment, L refers to an overlap due to a correction or change, and T indicates postmiles classified as temporary (for a full list of prefixes, seeCalifornia postmile § Official postmile definitions).[1] Segments that remain unconstructed or have been relinquished to local control may be omitted. The numbers reset at county lines; the start and end postmiles in each county are given in the county column.
