Rail to Rail/River Active Transportation Corridor

Project Overview

The Rail to Rail/River Active Transportation Corridor Project – spanning approximately 10 miles – will convert an existing, underutilized railroad right-of-way (ROW) into a multi-purpose pedestrian and bicycle transportation corridor on the western end of the corridor and create connections to the Los Angeles River on the eastern end of the corridor.

Upon completion, the Rail to Rail/River Active Transportation Corridor Project will link neighborhoods, schools, and other key destinations through the heart of South Los Angeles. Most notably, the Project will facilitate:

  • New east-west pedestrian and bicycle linkages
  • Connections to multiple Metro and municipal bus lines along Slauson Avenue
  • Connections to four major north-south Metro transit lines:  The A Line (Blue), the J Line (Silver), and the future Crenshaw/LAX Line
  • The future West Santa Ana Branch Transit Corridor (WSAB)
  • Connections to the Los Angeles River & the Los Angeles River Path
  • Enhancements upon the existing Los Angeles County bicycle network

The Project will provide a pedestrian and bicycle corridor that will connect the Cities of Los Angeles, Inglewood, Huntington Park, Vernon, Maywood, Bell, and parts of unincorporated Los Angeles County. The Project area is largely composed of a mix of high-density neighborhoods, commercial centers and industrial uses.

The Rail to Rail/River Active Transportation Corridor Project is a single pedestrian and bicycle corridor composed of two distinct segments, each in a different phase of development. Segment A is the Rail to Rail component and Segment B is the Rail to River component. Together, they will form one path, stretching from South Los Angeles to the Los Angeles River.

Project Background

In 2012, the Metro Board of Directors (Metro Board) requested staff to assess the feasibility of repurposing the Local North Section of the Metro-owned Harbor Subdivision rail right-of-way (ROW) as an active transportation corridor. The resulting Rail to River Intermediate Active Transportation Corridor Feasibility Study (Feasibility Study) in 2014 indicated that a bike and pedestrian path along the Project corridor would provide significant enhancements to the regional transportation network, while creating innovative environmental, economic, and mobility benefits for the surrounding communities. In October 2014, the Metro Board approved funding for environmental clearance, design, and outreach for Segment A, as well as the Alternative Analysis for Segment B.

Currently, pedestrians and bicyclists travel along the Project corridor with very few facilities to support their travel patterns. Safe, comfortable, and convenient access for existing bicycle and pedestrian volumes is significantly impeded by restricted amenities on the south side of Slauson Avenue, with narrow and over-crowded sidewalks.  On the north side of Slauson Avenue (location of the Project ROW), sidewalks are non-existent, creating inadequate passage for all users, including bus rider access to multiple bus stops along the Project corridor.

The 2014 Feasibility Study generated a high level of interest from members of various communities and received attention from local and regional media news sources.  The Project receives strong support from local jurisdictions, community organizations, and elected officials because it promotes improved traveling conditions, encourages utilization of mass transit, and provides opportunities for upward mobility in underserved areas.

The improved connectivity of public transportation networks will provide local residents with more transportation choices by connecting to the Metro A Line, J Line (through the I-110 Harbor Freeway Transit Way), and the future Crenshaw/LAX and WSAB LRT Lines. The Harbor Subdivision rail right-of-way has been underutilized for many years, but this project will support many local and regional planning efforts (such as Metro’s First Mile Last Mile Strategic Plan, Complete Streets, and 2012-2035 Regional Transportation Plan and Sustainable Community Strategies) to improve the quality of life in Los Angeles County.

Segment A: Rail to Rail

Segment A of the project is referred to as “Rail to Rail,” because it connects the future Metro Crenshaw/LAX Line to the Metro A Line (Blue). The “Rail to Rail” portion of the project is approximately 5.6 miles in length, stretching east along the Harbor Subdivision rail right-of-way, following Slauson Avenue through South Los Angeles to the Metro A Line Slauson Station. Once complete, Segment A will provide connections to three major transportation hubs:

  • The Metro A Line and future WSAB Slauson Station,
  • The Metro J Line (Silver) at the I-110 freeway Slauson Station, and
  • The future Metro Crenshaw/LAX Line’s Fairview Heights Station

Segment A has concluded the Environmental Clearance and Preliminary Engineering phase and is completing the Final Design/Engineering and will be followed by the Construction phases.

Segment A is funded by a combination of federal, state and local funding sources. In October 2015, the Project became the first of its kind to be awarded funding from the Federal Transportation Authority (FTA) in the form of a Department of Transportation (DOT) TIGER Grant. Additional funding was provided by a Caltrans ATP Grant and Metro.

Latest Updates

Segment A (Rail to Rail) initial construction work activities are anticipated to begin February 1, 2021 and continue through June 2021.


  • Site Clearing: clearing the Metro right-of-way of all materials and equipment, including removal of rail track and equipment, encampments, unauthorized vendors, property, and vehicles.
  • Soil Excavation, treatment, and disposal


  • Railroad ROW north of Slauson Av from Long Beach Av to West 11th Av

Approximate Timeline (intermittent)

  • Monday, February 1, 2021 – June 30, 2021
  • 6 :30 am - 3:30 pm (Monday - Friday, Weekdays only)

Segment B: Rail to River

Segment B of the project is referred to as “Rail to River,” because it connects the Metro A Line (Blue) east to the Los Angeles River. In March 2017, Metro concluded the Alternatives Analysis (AA) for Segment B. As part of the AA, Metro studied four alternatives for continuing the active transportation corridor from Segment A at the Metro A Line (Blue) Slauson Station to the Los Angeles River.  With community and stakeholder input, the Metro Board of Directors adopted the Randolph St Alternative as the Locally Preferred Alternative (LPA). The West Santa Ana Branch (WSAB) Transit Corridor is also planned along Randolph St, sharing approximately 2.3 miles with the Segment B LPA. Technical analyses of the WSAB and Randolph LPA determined that the existing right-of-way could not accommodate both projects. As a result, a Supplemental Alternatives Analysis (SAA) is being conducted to re-evaluate Randolph St and other additional/potential alternatives to continue the active transportation corridor further east to the LA River.

The AA and SAA work for Segment B is funded by Metro local funds.

Community Meetings

Previous Segment B Meetings

Metro held community meetings via Zoom on Tuesday, May 11 and Saturday, May 15, 2021. Both meetings provided the same information. If you missed the meetings, please use the links below to access the video recording of the meeting and the meeting materials.

Community Survey

Metro is seeking additional input on Segment B of the Rail to River Active Transportation Corridor Project. Please take a few minutes to complete the project survey by June 4. Your input is needed to identify your priorities for each of the proposed alternatives. Don’t forget to share the survey link with friends and family!.
