Extra Transbay Tube? BART looks at long term planning

BARTWhile Muni contemplates bus rapid transit and light rail extensions, BART is looking at a long term plan that may include some major capacity improvements, such as a new Transbay Tube and fourth track through downtown Oakland, as well as further extensions into the East Bay suburbs. San Francisco could also be served by a Geary or Van Ness line in some scenarios.

This is a 50 year conceptual plan, so don’t expect tunnel boring machines on your block just yet.
