The Muni Subway Expansion project is based on a simple idea: make the best use of the resources we have. That means our subway tunnel and our train cars. We should make one of Muni's rail lines a full subway line, providing a backbone of fast, reliable, high-capacity transit that runs across the whole city – from the very southwest corner of San Francisco to the Embarcadero on the northeast. Introducing a full subway would unlock the ability to utilize the existing subway tunnel to its fullest capacity. The line selected as the spine, the M Ocean View, connects the major job centers and dense planned housing in eastern San Francisco with the densest and fastest-growing node in Southwest San Francisco. This is about making the Metro system work better for everyone.
This big idea is still in very early stages of planning. As a part of the planning phase, we have been focused on defining the project’s conceptual design. The next step is for it to be considered for prioritization as a part of a citywide effort called ConnectSF that will identify the full universe of major transit investments that we need to provide a world class transit system.
