| BART Silicon Valley Phase II Extension | CA | heavy rail | Under Construction | Six-mile, four-station BART extension from Berryessa/North San José through downtown San José to Santa Clara, about 5 miles of it in a single large-bore tunnel. Early works at the west portal are under way, but tunneling has slipped to early 2028 and VTA expects its next cost estimate to be significantly above $12.7B. | Nov 13, 2026 |
