Los Angeles could soon have a new underground rail connection linking the San Fernando Valley with the Westside, offering an alternative to one of the region’s most congested driving corridors. The Sepulveda Transit Corridor Project is moving through environmental review, with Metro hosting a new round of public meetings starting November 4, 2026, to gather feedback on the proposed route.
The selected plan calls for a 12.3-mile heavy rail subway with seven underground stations, creating new transfer opportunities across the county’s transit network.
Where will the new Sepulveda Pass subway line go?
The selected route will serve major destinations including UCLA and several existing Metro connections. Starting from the southern end, the proposed stations are:
- Expo/Sepulveda (E Line connection)
- Santa Monica Blvd/Sepulveda
- Wilshire/Westwood (D Line connection)
- UCLA
- Ventura/Sepulveda
- G Line/Sepulveda
- Van Nuys Metrolink Station
The route provides connections to the E Line at Expo/Sepulveda, the D Line at Wilshire/Westwood, the G Line at Sepulveda, and Metrolink at the northern terminus. An additional connection to the future East San Fernando Valley Light Rail at the Van Nuys Metrolink station will further expand access across the Valley.
According to Metro, the trip between the G Line station and the D Line in Westwood will take approximately 10 minutes. The full journey between the Valley and the Westside is expected to take less than 20 minutes, compared with driving trips that can take 40 to 80 minutes depending on traffic.
What to know about the Sepulveda Pass subway
The project has been under consideration for years. The chosen design features a single-bore tunnel and automated trains, with service planned every 2.5 minutes during peak hours.
The project carries a preliminary estimated price tag of $24.2 billion, based on Metro’s 2023 estimate for the selected rail alternative. Metro is also considering a phased construction approach, prioritizing an initial 8.4-mile operating segment between the G Line and the D Line in Westwood.
The project remains in the planning and environmental review phase, and Metro has not yet announced a final construction completion date.
