Sepulveda Transit Corridor

A high-capacity rail line connecting the San Fernando Valley and the Westside — transforming how Los Angeles moves

Project Type

Mixed-Mode

Current Phase

Planning

The Sepulveda Transit Corridor is a proposed high-capacity rail line that will provide a crucial north-south transit connection between the San Fernando Valley, the Westside and eventually Los Angeles International Airport (LAX). Currently under environmental review, Metro is evaluating multiple alternatives — including heavy rail and monorail technologies — to address one of the most heavily traveled and congested corridors in Los Angeles County.

In June 2025, Metro released a Draft Environmental Impact Report (DEIR) under the California Environmental Quality Act (CEQA). The DEIR analyzed a range of rail transit modes, alignments, and station locations to address the transportation needs of the Sepulveda Corridor. The latest information and DEIR materials can be found on the Project Hub.

Metro is reviewing the comments received on the DEIR and will identify a Locally Preferred Alternative (LPA) to recommend to the Metro Board of Directors.
