The C Line Extension to Torrance is a project to extend the Los Angeles County Metropolitan Transportation Authority C Line (formerly known as the Green Line) from its terminus in Redondo Beach to Torrance. The project was known as the South Bay Metro Light Rail Extension in planning.


Metro is currently working on the initial environmental study of a corridor extension of the C Line from its Redondo terminus toward the southeast. The extension would roughly follow the Harbor Subdivision right of way into the South Bay, to the proposed Torrance Regional Transit Center (RTC).[1]

Study of the South Bay Extension was necessary to initiate publication of a Draft Environmental Impact Report (DEIR). The study was expected to be completed in 2011, but the project was placed on hold in Spring 2012 due to uncertain funding.[citation needed] With the passage of Measure M in 2016, $619 million was earmarked for the Green Line Extension south and the study resumed. The environmental impact report is scheduled to be released in March 2022.[2]

Route selection

Four potential routes for the extension starting at Redondo Beach station were initially considered. The station in Lawndale was eliminated due to community opposition.[2]

Metro authorized two of four alternatives to move forward: Alternative #1 and Alternative #3. Metro staff recommended the two alternatives into the draft environmental impact statement (DEIR) status for further analysis and refinement in September 2018. The study area includes the former Harbor Subdivisions right of way. The extension study includes the Redondo Beach station to the Torrance Transit Center, a 4.5-mile (7.2 km) extension study area.[3] Metro began composing the DEIR in January 2021.[4]

DEIR Alternative[3] Description Ridership
Estimated cost
Alternative 1: ROW Overcrossing A Light rail transit (LRT) line heading south from the Redondo Beach station on the ROW of Harbor Subdivision. A stop at the Redondo Beach Transit station adjacent Pacific Crest Cemetery between Grant Ave and 182nd st. On 190th st. it continues southeast along the ROW with a terminus at the Torrance Transit Center. A 7-minute ride. No station at Manhattan blvd./Inglewood Ave. intersection. 10,340 $0.893
Alternative 2: Hawthorne to 190th St A LRT line heading southeast. An aerial segment is needed over Manhattan Beach Boulevard to reach Hawthorne Boulevard immediately southeast of Redondo Beach station. Then heads south on Hawthorne Boulevard. Two new stations, a South Bay Galleria mall station and a station at Torrance Transit Center in Torrance along the Harbor Subdivision ROW at 465 Crenshaw Blvd. A 9-minute ride. 10,640 $1 to 1.2

The following table shows all potential metro stations, and the alternatives for which they apply:

Station Options Alt 1 Alt 2 Connecting Rail/Bus Service Community
Redondo Beach station (already built) × × Redondo Beach
Redondo Beach Transit Center station × Beach Cities Transit Redondo Beach
South Bay Galleria station × Redondo Beach
Torrance Transit Center station × × Torrance Transit Torrance

According to the LA County Expenditure Plan (Measure M), groundbreaking for the project is currently[when?] scheduled for 2026, with expected opening in 2030–2033. The timeline is expected to be accelerated under the Twenty-eight by '28 initiative.[5]
