LA Metro Board says heck yeah to proposed Sepulveda Transit Corridor train route — with a warning

The Los Angeles Metro Board unanimously voted Thursday to proceed with developing a 14-mile-long subway under the Santa Monica Mountains. It’s one of the first significant steps in what city and county leaders are describing as the region's most consequential transit project and perhaps one of the most important in the country.

Metro staff said in a report to its board that it has secured funding through county tax measures for about 14% of the $24.2 billion it’s preliminarily estimated to cost to build the route, which will involve extensive tunneling. They added the cost estimate would be updated as further refinements are made, but having this amount of funding secured is “not uncommon” for projects early on in development.

Still, leaders underscored that while the need for a rail link between the Valley and Westside couldn’t be overstated, staff for the countywide transportation agency should remain mindful of financial constraints and push for cost reductions through the next several years before shovels hit the ground.

“Ambition matters, dreaming big matters, but honesty matters too,” L.A. City Councilmember Katy Yaroslavsky, who also is a member of the Metro Board, said during Thursday’s meeting. “We can't afford to approve transformative projects without being clear about the path to funding and delivery.”

The price tag certainly is “eye-popping” and Metro’s “largest project to date,” as Ray Sosa, the chief planning officer for the agency, recently wrote in an op-ed about the project.

With today’s vote progressing the project, the Metro Board enthusiastically endorsed the investment, for now, in theory.

The project and selected route 

The Sepulveda Transit Corridor, as the project is known, was conceived to relieve Angelenos of the sometimes 90-minute drive between the Valley and Westside via the 405 Freeway, provide a crucial artery to connect with other regional rail and bus routes and link residential areas to job centers.

In June 2025, Metro released its draft environmental review of five different subway and monorail options. Of the more than 8,000 public comments Metro received, fewer than 70 expressed opposition to the project as a whole, according to agency staff.

Metro staff in January published its recommendation to move forward with further study of a modified version of one of the subway options.

That’s what the transportation agency’s board approved Thursday.

The route is projected to see as many as 124,000 rides per day and reduce the total amount people would otherwise travel by car by nearly 800,000 miles a day.

An end-to-end trip on the proposed route between Valley and the Westside is slated to take 20 minutes, with trains arriving every 2.5 minutes at peak times.

Station locations for the proposed train would connect to the Metro D, E and East San Fernando Valley rail lines, the Metrolink stop in Van Nuys and also the G bus rapid-transit line. Crucially, the route also will stop at UCLA, which over the years had become a non-negotiable necessity among students and other advocates of the train.

“Higher education deserves to be easily accessible for everyone,” Mariela Diaz, a UCLA commuter student who described herself as low income, said at the meeting Thursday. “Future UCLA students deserve to have their first on-campus station.”

As it’s currently planned, there wouldn’t be a stop providing direct access to the Getty Center, for which the museum had been publicly campaigning.

L.A. Mayor Karen Bass, who has a seat on the Metro Board, asked Thursday that agency staff report back on “transportation alternatives to address fast and last-minute connections to the Getty Center.”

The proposed route would run from Van Nuys to the Westside.

Report details economic benefits 

A report from the Los Angeles County Economic Development Corporation details how construction would generate as much as $40 billion in economic output and spur more than $16 billion in labor income countywide.

Leaders urge continued engagement and not to compromise on vision 

Today’s vote directed Metro staff to focus on the proposed route for forthcoming technical and environmental analyses and clearances, as well as to further refine design and cost estimates.

There also will be continued community engagement.

Yaroslavsky amended the item the board approved Thursday to include language asking Metro staff to, among other tasks, report back on a community engagement plan focused on the communities that might be impacted by tunneling or construction and to maintain a publicly accessible outreach calendar.

Metro’s final environmental documents, which will be the culmination of the continued engagement and study, will be subject to future approval from the board.

When construction starts, the focus will first be on the middle segment of the train running from the G-line stop in Van Nuys to the future D-line stop in Westwood.

The additional segments on the north and south sides of the route would be built afterward.

Councilmember Imelda Padilla, who also is on the Metro Board, urged that the full route be built as envisioned.

“Phasing is a given, but the true value of this line will not be realized until it is fully built out,” Padilla said.
