Eastside Transit Corridor Phase 2

Metro is evaluating an extension of the Metro L Line (Gold) further east from its current terminus at Pomona Bl and Atlantic Bl in East Los Angeles potentially through the cities of Commerce, Montebello, Pico Rivera, Santa Fe Springs and Whittier.

The proposed line would travel south along Atlantic Bl underground from the current Metro L Line (Gold) terminus at Pomona Bl and Atlantic Bl to the Citadel Outlets in Commerce. The route would then proceed east along Washington Bl via aerial and/or at-grade (street level) configurations ending at Lambert Rd in Whittier.

Proposed stations along this route that will be further evaluated include:*

  • Relocated Atlantic Station in East Los Angeles
  • Atlantic/Whittier Station in East Los Angeles
  • The Citadel Station in Commerce
  • Greenwood Station in Montebello
  • Rosemead Station in Pico Rivera
  • Norwalk Station serving unincorporated Los Nietos, Whittier and Santa Fe Springs
  • Lambert Station in Whittier

In February 2020, the Metro Board of Directors considered options for studying the Eastside Transit Corridor Phase 2 Project (Project). Based on technical findings the board withdrew the SR 60 and Combined Alternatives from consideration in the environmental process.

The board also directed that a separate feasibility study be completed along the SR 60 corridor, in the San Gabriel Valley, to identify potential mobility solutions and options in the short and long-term.

The board actions also included proceeding with the California Environmental Quality Act (CEQA) Environmental Impact Report (EIR) process and discontinuing the National Environmental Policy Act (NEPA) federal study for the Project.

These actions will help focus the environmental study and advance the accelerated schedule goals for the Project

*Station locations will be evaluated thoroughly to ensure each proposed station has ridership demand, economic development opportunities, first/last mile connections, among other factors.


The 2014 Draft EIS/EIR for the Eastside Transit Corridor Phase 2 Project was released in August 2014. Due to comments received, the Metro Board of Directors deferred the selection of a Locally Preferred Alternative (LPA). Instead, the Metro Board of Directors directed staff to carry out technical work to:

  1. Conduct additional technical investigation to address major areas of concern raised by cooperating agencies, corridor cities and stakeholders;
  2. Identify a new north-south connection for the Washington Alternative and;
  3. Explore the feasibility of operating both the SR 60 and Washington Alternatives

In May 2017, a technical study for the Eastside Transit Corridor Phase 2 Project was completed. That study addressed major areas of concern raised by agencies, corridor cities and stakeholders. The 2017 technical study identified a new north-south connection between the Atlantic/Pomona Gold Line Station and Washington Bl. The study also introduced a Combined Alternative that proposed the build out of both SR 60 and Washington Alternatives. Based on the 2017 technical work, the Metro Board of Directors updated the Project Definition to include three build alternatives and authorized reinitiating the environmental review process to assess the benefits and impacts of building and operating:

  1. SR 60 Alternative
  2. Washington Alternative
  3. Combined Alternative (builds both SR 60 and Washington alternatives)

In 2019, the environmental process was reinitiated with a Notice of Intent to prepare a Supplemental Draft Environmental Impact Statement (EIS)/Recirculated Environmental Impact Report (EIR) to include updated environmental analysis, continued coordination with regulatory agencies, more advanced engineering design and refinement of the alternatives under consideration at that time (SR 60, Washington, and Combined). Scoping meetings were held to receive input from the pubic and stakeholders.

In February 2020, the Metro Board of Directors withdrew the SR 60 and Combined Alternatives from consideration in the environmental process, based on technical study findings and public input during scoping. The board decided to proceed with the California Environmental Quality Act (CEQA) for the environmental review process to discontinue the National Environmental Policy Act (NEPA) study for the Project. These actions will help focus the environmental study and advance the accelerated goals for the Project.

The board also directed that a separate feasibility study be completed along the SR 60 corridor, in the San Gabriel Valley, to identify potential mobility solutions and options in the short and long-term.

Based on the Board actions in February 2020, the EIR will proceed with the Washington Alternative and a reasonable range of alternatives as required by CEQA including No Action, Initial Operating Segments, alternative maintenance and storage facility location options and design variations. This process will continue with robust public engagement and outreach process to include interested stakeholders and communities along the project corridor. As the environmental study advances, opportunities for community input will be provided at key milestones in the planning process.


Washington Alternative
The Washington Alternative would travel south along Atlantic Bl in an underground configuration from the current Metro L Line (Gold) terminus at Pomona Bl and Atlantic Bl to the Citadel Outlets in Commerce. The route then proceeds east along Washington Bl via aerial and at-grade (street level) configurations ending at Lambert Rd in Whittier. Proposed stations* along this route that will be further evaluated include:

  • Relocated Atlantic Station in East Los Angeles
  • Atlantic /Whittier Station in East Los Angeles
  • The Citadel Station in Commerce
  • Greenwood Station in Montebello
  • Rosemead Station in Pico Rivera
  • Norwalk Station serving unincorporated Los Nietos, Whittier and Santa Fe Springs
  • Lambert Station in Whittier

Initial Operating Segments (IOS)
Metro is evaluating potential Initial Operating Segments (IOS) options as part of the Recirculated Draft EIR to potentially accelerate delivery of the Project faster than assumed in the Measure M Expenditure Plan. Any IOS must be able to operate as a stand-alone system and include a maintenance and storage facility. This approach is similar to the phased-construction of most Metro rail projects, including:

  • Metro B Line (Red) (built in three segments)
  • Metro D Line (Purple) (two of three segments currently under construction)
  • Metro E Line (Expo) Line (built in two segments)
  • Metro L Line (Gold) Foothill (three of four segments currently under construction)

*Station locations will be evaluated thoroughly to ensure each proposed station has ridership demand, economic development opportunities, first/last mile connections, among other factors.


The Metro Board’s actions in February 2020 included proceeding with the California Environmental Quality Act (CEQA) for the environmental review process and discontinuing the National Environmental Policy Act (NEPA) study for the Project. These actions will help focus the environmental study and advance the accelerated goals for the Project.

The reinitiated environmental process will include the development of a Recirculated Draft EIR – under CEQA – to update the 2014 Draft EIS/EIR. This process includes advanced conceptual engineering, environmental analysis, and ongoing outreach efforts. In addition, focused technical analyses will:

  • Evaluate various design refinements on alternatives to address comments received on the 2014 Draft EIS/EIR
  • Update ridership and travel time projections
  • Study potential environmental impacts
  • Analyze grade crossings
  • Identify locations for maintenance and storage facilities
  • Develop IOS options

Throughout the environmental review phase, Metro staff will continue to provide project updates to stakeholders and provide the necessary tools and resources to keep communities informed. Opportunities to provide input will be provided at key milestones in the planning process.

Please be sure to sign-up to continue to receive project updates and details on other opportunities to get involved.


Thanks to voter support of the Los Angeles County Traffic Improvement Plan presented to voters as Ballot Measure M in November 2016, Metro allocated $6 billion for this project. Funding for this project that has been programmed in two cycles (per the plan's funding schedule):

  • Cycle 1 allocates $3 billion in 2029 (one alignment)
  • Cycle 2 allocates $3 billion in 2053 (second alignment)

The project is also identified as high priority for potential acceleration. If funding can be secured prior to the anticipated 2029 funding cycle, the goal would be to build it in time for the 2028 Summer Olympic and Paralympic Games.
