Program Development
Link21 is a multiyear, multiphase program to create an integrated rail network for Northern California.
Link21 is currently in an early stage of development. In this phase, BART and Capitol Corridor are building a robust framework for technical analyses and laying the groundwork for transparent and inclusive decision-making. BART and Capitol Corridor are soliciting the public's input on these early-stage evaluations.
At the end of this early stage, there will be an initial list of program alternatives. The Link21 program alternatives will include several projects that act together to achieve the program vision and goals.
In Phase 1, beginning in 2021, the Link21 program alternatives will be further studied. The public will again be asked to provide significant input. A preferred program alternative will be identified by the end of Phase 1.
The preferred program alternative will be made up of one or more projects. BART and/or Capitol Corridor may be responsible for some of the projects. Other projects may be planned or implemented by other transportation agencies.
One of the projects within the Link21 Program will be a new rail crossing between Oakland and San Francisco. For decades, transportation planners have identified the need for a new crossing to best streamline and integrate Northern California's rail network and to provide resiliency and redundancy to the existing rail service.
In Phase 2, beginning in 2024, the projects will be refined. BART and Capitol Corridor — with the public's input — will determine which preferred project(s) will carry forward to full design and construction. Other agencies may take responsibility for delivering related project(s).
A detailed environmental analysis of the preferred project(s) will also be performed in Phase 2. The public's contributions, opinions, and feedback will continue to shape and guide the project(s).
In Phase 3, beginning in 2028, final engineering design and construction packages will be developed. Each preferred project will then be constructed, tested, and made ready for service.
All phases are dependent on available funding. BART and Capitol Corridor will continue to identify funding sources and work to secure the support and funding needed to bring the full Link21 vision to reality.
