**State Route 42** (**SR 42**) is a [decommissioned state highway](/source/Decommissioned_highway) in the [southern](/source/Southern_California) region part of the [U.S. state](/source/U.S._state) of [California](/source/California), running along **Manchester Avenue**, **Manchester Boulevard** and **Firestone Boulevard** in [Los Angeles](/source/Los_Angeles) and the cities south of it. In its final official routing that lasted from 1968 to 2000, SR 42 ran from [State Route 1](/source/State_Route_1_(California)) west of [Inglewood](/source/Inglewood%2C_California) (near [Los Angeles International Airport](/source/Los_Angeles_International_Airport)) east to what was then a direct interchange with [Interstate 5](/source/Interstate_5_in_California) in [Norwalk](/source/Norwalk%2C_California).[1] Though signed as SR 42, it was officially [Route 105](/source/California_State_Route_105_(1968%E2%80%931993)) until it was replaced by the parallel [Interstate 105](/source/Interstate_105_(California)) on October 14, 1993.[2] The entire route was deleted from the [California Freeway and Expressway System](/source/California_Freeway_and_Expressway_System) in 2000, with the remaining portion of SR 42 being relinquished to local jurisdictions in that year.[3] The direct interchange with I-5 was later demolished in 2013 in favor of widening that portion of the Interstate.[1] However, some SR 42 signs may still remain along the route.[3]

## Route description

State Route 42 began at [Lincoln Boulevard](/source/Lincoln_Boulevard_(Southern_California)) ([State Route 1](/source/State_Route_1_(California))) as Manchester Avenue. East of [Sepulveda Boulevard](/source/Sepulveda_Boulevard), Manchester Avenue crossed into [Inglewood](/source/Inglewood%2C_California), where it is known as Manchester Boulevard. It jogged about two blocks to the north just west of [Interstate 405](/source/Interstate_405_(California)), and back to the south after passing downtown Inglewood. Upon crossing back into Los Angeles, it again became Manchester Avenue.

At [Central Avenue](/source/Central_Avenue_(Los_Angeles)), SR 42 entered the unincorporated community of [Florence-Graham](/source/Florence-Graham%2C_California). It then became Firestone Boulevard and passed through [South Gate](/source/South_Gate%2C_California) and [Downey](/source/Downey%2C_California), and ended in [Norwalk](/source/Norwalk%2C_California) at a merge with [Interstate 5](/source/Interstate_5_(California)) (the [Santa Ana Freeway](/source/Santa_Ana_Freeway)).

Two [Metro](/source/Los_Angeles_County_Metropolitan_Transportation_Authority) stations serves the corridor:

- [Firestone](/source/Firestone_station)

- [Manchester](/source/Manchester_station_(Los_Angeles_Metro))

## History

**Legislative Route 174** was defined in 1933 to run from [pre-1964 Legislative Route 60](/source/Pre-1964_Legislative_Route_60_(California)) west of [Inglewood](/source/Inglewood%2C_California) east to [pre-1964 Legislative Route 2](/source/Pre-1964_Legislative_Route_2_(California)) near [Santa Ana](/source/Santa_Ana%2C_California).[4] It was signed as **State Route 10** in the initial signage of routes in 1934, running from [State Route 3](/source/State_Route_3_(California)) (now [State Route 1](/source/State_Route_1_(California))) to [U.S. Route 101](/source/U.S._Route_101_(California)) near the present junction of [Interstate 5](/source/Interstate_5_(California)) and [Anaheim Boulevard](/source/Anaheim_Boulevard). (US 101 and LR 2 left the current I-5 alignment north onto Anaheim Boulevard, eventually entering downtown Los Angeles via present [State Route 72](/source/State_Route_72_(California)).)

Note: the present alignment of I-5 between Chapman Avenue in [Anaheim](/source/Anaheim%2C_California) and Main Street in Santa Ana was also part of LR 174, after a short [concurrency](/source/Concurrency_(road)) of LR 2 and LR 174 in Anaheim. LR 2 used those two streets through [Orange](/source/Orange%2C_California), but US 101 was moved to LR 174 once it was built, and so that part of LR 174 was never signed as SR 10. The bypassed section of LR 2 became [State Route 51](/source/State_Route_51_(California)) in the [1964 renumbering](/source/1964_state_highway_renumbering_(California)), but was removed from the state highway system in 1965.[5]

By 1942, the piece of SR 10 east of [State Route 19](/source/State_Route_19_(California)) ([Lakewood Boulevard](/source/Lakewood_Boulevard)) had been designated [U.S. Route 101 Bypass](/source/U.S._Route_101_Bypass_(Los_Angeles%2C_California)).[6] [U.S. Route 101](/source/U.S._Route_101_(California)) moved to the present [Interstate 5](/source/Interstate_5_(California)) alignment, formerly US 101 Bypass, by 1959, and SR 10 was truncated to the present I-5/Firestone Boulevard junction.[7]

State Route 10 Location Inglewood - Norwalk Existed 1934–1960

Around 1960, SR 10 was renumbered to State Route 42 due to the nearby [Interstate 10](/source/Interstate_10_(California)) (numbered in 1957).[3] This change, which would have normally happened in the [1964 renumbering](/source/1964_state_highway_renumbering_(California)), was done early due to the closeness of I-10. Route 42 was legislatively defined in that renumbering, running not only from SR 1 to I-5, but beyond to [State Route 91](/source/State_Route_91_(California)) in [Anaheim Hills](/source/Anaheim_Hills%2C_Anaheim%2C_California). This route split from the existing SR 42 in [Norwalk](/source/Norwalk%2C_California) and ran east along unbuilt [pre-1964 Legislative Route 176](/source/Pre-1964_Legislative_Route_176_(California)) to the intersection of [State Route 39](/source/State_Route_39_(California)) ([Beach Boulevard](/source/Beach_Boulevard_(Orange_County%2C_California))) and [Imperial Highway](/source/Imperial_Highway). East of SR 39, Imperial Highway was state-maintained, and carried pre-1964 LR 176 and post-1964 SR 42 to its end at SR 91.[8] The whole route, from SR 1 to SR 91, had been added to the [California Freeway and Expressway System](/source/California_Freeway_and_Expressway_System) in 1959.[9][10]

State Route 105 Location Inglewood - Norwalk Existed 1968–1993

In 1965, the unbuilt part from [Interstate 605](/source/Interstate_605_(California)) east to SR 39 was transferred to [State Route 90](/source/State_Route_90_(California)), which had been defined in 1964 to end at I-605; this left a gap in SR 42. The part of SR 42 west of I-605 was added to the [Interstate Highway System](/source/Interstate_Highway_System) as [Interstate 105](/source/Interstate_105_(California)) in March 1968,[11] and the legislative changes were made that year - that piece became Route 105, and the piece east of SR 39 became a further extension of SR 90.[3]

Despite being officially Route 105 since 1968, the route continued to be signed as SR 42, not only along its defined alignment from SR 1 to I-605, but past I-605 to [Interstate 5](/source/Interstate_5_(California)) (which had loosely become part of SR 90 in 1965).[12]

Interstate 105 was constructed from 1982 to 1994.[9] Even after the new route was finished, the old route continued to be signed as SR 42, even after the last section was relinquished in mid-2000.[3] Some signs still remained in 2004.[13] Since the widening of Interstate 5 between Interstate 605 and the Los Angeles-Orange County line, Firestone Boulevard does not connect with it anymore, instead ending at Bloomfield Avenue. Access to Firestone Boulevard from I-5 is now via [Rosecrans Avenue](/source/Rosecrans_Avenue).[1]

## Major intersections

Except where prefixed with a letter, [postmiles](/source/California_postmile) were measured on the road as it was in [1964](/source/1964_state_highway_renumbering_(California)), 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, see [California postmile § Official postmile definitions](/source/California_postmile#Official_postmile_definitions)).[15] Segments that remain unconstructed or have been relinquished to local control may be omitted. The entire route was in [Los Angeles County](/source/Los_Angeles_County%2C_California).
