| Valley Link | CA | commuter rail | Env. Review | 22-mile first phase of a planned 42-mile regional rail line from the Dublin/Pleasanton BART station over Altamont Pass to Mountain House, mostly in or beside the I-580 corridor. Phase 1 was environmentally cleared in 2024–25, but its estimated cost has roughly doubled to $4.4B. The authority has split it and is advancing an 11-mile Phase 1A to the Vasco Road ACE station in Livermore with battery-electric trains, targeted for 2032; Phase 1B to Mountain House has no construction funding. | Nov 13, 2026 |
