Link21 is a complex program that builds on decades of previous studies and projects. Above, you'll find our latest webinar presentation, which gives an overview of where the Program is today and how Link21 will shape the future.
Additionally, here are several documents that can help you understand the origin of—and thinking behind—Link21.
- View fact sheets put together by the Link21 Program on Equity and Inclusion, the Program overall, the Market Analysis, and Phase 1 work.
- Read why a new transbay passenger rail crossing between Oakland and San Francisco will improve travel in the Bay Area and beyond in the report "The Megaregional Case for a New Transbay Rail Crossing" by the Bay Area Council Economic Institute (BACEI). This report was made possible by a Transit and Intercity Rail Capital Program (TIRCP) grant from the California State Transportation Agency (CalSTA).
- Find out about the early Link21 ideas and concepts we evaluated, the evaluation findings, and recommendations that informed further development of concepts in the Appendix A: Exploratory Evaluation Report Executive Summary and the Appendix B: Round 1 Evaluation Report Executive Summary (full reports are available upon request).
- See the California Department of Transportation's (Caltrans) vision for rail travel in the state in the Executive Summary of the 2018 California State Rail Plan. If you prefer, you can read the full 2018 California State Rail Plan.
- Understand the capacity limitations of our current transit network through the Oakland–San Francisco transbay corridor in the Metropolitan Transportation Commission's (MTC) Core Capacity Transit Study (CCTS). The CCTS identifies and prioritizes the major investments, including new BART and Regional Rail (commuter, intercity, and high-speed rail) crossings, that are needed to address these limitations today and in the future.
- Compare the potential effectiveness of different San Francisco Bay crossings in the MTC’s 2019 white paper Crossings: Transformative Investments for an Uncertain Future. This white paper is part of MTC's larger Horizon effort, which identified a new transbay passenger rail crossing as the most cost-effective transit expansion megaproject in the Bay Area.
- Learn why the Bay Area Council Economic Institute sees the 21-county area as an interconnected Northern California Megaregion and makes The Case for a Second Transbay Transit Crossing.
- In summer 2023, Link21 hosted or participated in several virtual and in-person events to allow the public different engagement opportunities to learn and provide input about train service improvements that Link21 concepts could provide. See below for highlights.
- In fall 2022, Link21 hosted or participated in several virtual and in-person events to keep the public informed and provide opportunities to provide input on Link21 example concepts. Read our Fall Engagement Summary for a full picture, but here is a high-level overview:
- Virtual community meetings and office hours
- Presentations to the BART and CCJPA Board of Directors
- During Phase 0, we hosted or participated in several events to keep the public informed. We gave people many opportunities to offer their thoughts on the Program and what good service means to them. Here’s a high-level overview:
