Sepulveda Transit Corridor

The Sepulveda Transit Corridor is a two-phased planned transit corridor in Los Angeles, California. Its first phase aims to connect the San Fernando Valley to the Los Angeles Basin through the Sepulveda Pass. A second phase would further extend the line southwards to connect with Los Angeles International Airport. The corridor is intended to relieve the heavily congested I-405 freeway through Sepulveda Pass and provide a fast public transit option on this north–south link. Proposed alternatives include heavy rail rapid transit (a subway) or a monorail line connecting the G Line in the Valley to the D Line and E Line on the Westside, and the K Line near Los Angeles International Airport. As of December 2024, the project is in the environmental review phase of planning and construction is expected to be funded via a combination of local Measure M revenue and applications to federal grants. Pending these two requirements, the first phase is projected to open in 2033–2035.
