Harbor Subdivision Transit Corridor Study masthead


The Harbor Subdivision is a freight rail corridor, approximately 26 miles in length, that traverses southwest Los Angeles County from Vernon to Wilmington. In the early 1990s, Metro purchased the portion of the corridor between Redondo Junction and Watson Yard, along with several other rail rights-of-way, to further the development of the region’s rapid transit system.

Metro has initiated an Alternatives Analysis Study (AA) for the Harbor Subdivision Transit Corridor. The study will examine potential transit service along the Metro-owned Harbor Subdivision. The study’s goals include:

  • Improving mobility in southwestern Los Angeles County by introducing high-frequency transit service options
  • Enhancing the regional transit network by interconnecting existing and planned rapid transit lines
  • Providing an alternative mode of transportation for commuters currently using the congested I-405 and I-110 corridors
  • Improving transit accessibility for residents of communities along the corridor
  • Encouraging a mode shift to transit, reducing air pollution and greenhouse gas emissions

The AA will evaluate a broad range of alternatives including Bus Rapid Transit (BRT) with dedicated bus lanes, various types of rail technology such as Light Rail Transit (LRT) and commuter rail , as well as “no-build” and Transportation Systems Management improvements.

Though alternatives will generally follow the Harbor Subdivision corridor, potential alignment and improvement options outside the immediate Harbor Subdivision right-of-way will also be studied.

In addition, the analysis will examine potential financing mechanisms outside the traditional funding sources commonly used for constructing and operating transit service.

At the conclusion of the AA, Metro staff will recommend a course of action to the Metro Board, including possibly proceeding with an environmental document consistent with both federal and state requirements.

Study Area

The study area will encompass approximately 85 square miles including the jurisdictions of Huntington Park, Vernon, City of Los Angeles, Hawthorne, Inglewood, El Segundo, Lawndale, Torrance, Manhattan Beach, Redondo Beach, Carson, Los Angeles County, and the port areas of Los Angeles and Long Beach.
