Adding second rail corridor across Bay could transform region’s transit system

Nearly half of unmet rail transit needs in Northern California could be mitigated by a plan to build a second transbay rail corridor between San Francisco and Oakland and link major transit networks across nearly two dozen counties, officials with the project said.

The plan, known as Link21, would connect 21 counties in the San Francisco Bay Area, Monterey Bay Area, greater Sacramento area and Northern San Joaquin Valley via multiple rail transit projects in an effort to reduce vehicle traffic and make public transit more accessible.
