|---|---|---|---|---|---|
| BART Silicon Valley Phase II Extension | VTA | 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 |
| Brightline West | Brightline West | high speed | Under Construction | Privately developed 218-mile, all-electric high-speed line between Las Vegas and Rancho Cucamonga, running mostly in the I-15 median, with four stations. Construction formally began in April 2024, but work has largely stalled because financing is incomplete: the company is waiting on a $6 billion federal loan, and bondholders have extended its deadlines into January 2027. | Nov 13, 2026 |
| California High-Speed Rail: Merced–Bakersfield | CHSRA | high speed | Under Construction | 171-mile first segment of California High-Speed Rail through the Central Valley, with stations at Merced, Fresno, Kings/Tulare and Bakersfield, built around a 119-mile civil section from Madera County to north of Bakersfield. Under construction with about 81 miles of guideway finished. The track contract was awarded in June 2026, and the 2026 Business Plan targets passenger service in 2033 on a pared-back 162-mile, mostly single-track version. | Nov 13, 2026 |
| Foothill Gold Line: Pomona to Montclair (A Line Extension) | Foothill Gold Line Construction Authority | light rail | Funded | Final 3.3-mile, two-station segment of the Metro A Line's Foothill extension, from Pomona to Claremont and Montclair along the Metrolink San Bernardino Line corridor. The 2.3-mile Pomona–Claremont section is funded with $798M in state money and in final design, with major construction expected from late 2027 and completion around 2031. The Claremont–Montclair section is on hold after San Bernardino County withdrew its support in 2025. | Nov 13, 2026 |
| East San Fernando Valley Light Rail Transit Project | LA Metro | light rail | Under Construction | 6.7-mile, 11-station street-running light rail line in the middle of Van Nuys Boulevard, from the Metro G Line in Van Nuys to San Fernando Road in Pacoima, with transfers to Metrolink at Van Nuys and at a new Pacoima Metrolink station. Major construction began in October 2026 on a $4.0 billion budget, and the line is due to open in 2031–2032. The originally planned 2.5-mile northern segment to Sylmar/San Fernando was dropped in favor of the Pacoima station. | Nov 13, 2026 |
| K Line Extension to Torrance | LA Metro | light rail | Env. Review | 4.7-mile, two-station light rail extension of the K Line (formerly the C Line Extension to Torrance) from Redondo Beach (Marine) Station to the Torrance Transit Center. In January 2026 the Metro Board certified the Final EIR and chose an elevated route along I-405 and Hawthorne Boulevard; the project is now in preliminary engineering with $1.13B of funding identified, and opening is targeted for late 2036. | Nov 13, 2026 |
| D Line Subway Extension Section 3 | LA Metro | heavy rail | Under Construction | 2.56-mile subway extension of the Metro D Line (formerly the Purple Line) from Century City/Constellation to Westwood, with two new underground stations at Westwood/UCLA and Westwood/VA Hospital. Tunneling is finished, the project was 85% complete in June 2026, and opening is planned for fall 2027. | Nov 13, 2026 |
| Southeast Gateway Line | LA Metro | light rail | Under Construction | 14.5-mile light rail line with nine stations from the A Line's Slauson station to Pioneer Boulevard in Artesia, mostly at grade on existing rail corridors including the former Pacific Electric West Santa Ana Branch. It was environmentally cleared in 2024, and advance utility work and early works are under way. Metro is aiming for a federal funding agreement by 2027 and completion by 2035. The roughly 4.8-mile northern segment to Union Station has no settled alignment and no funding. | Nov 13, 2026 |
| ACE Extension to Ceres and Merced (Valley Rail) | SJRRC | commuter rail | Under Construction | Southern branch of the Valley Rail program, extending Altamont Corridor Express commuter trains from Lathrop down Union Pacific's Fresno Subdivision to Ceres (Phase I) and then about 34 miles further to Merced (Phase II), with new stations in Manteca, Ripon, Modesto, Ceres, Turlock, Livingston and Merced. Construction began at the Lathrop Wye in 2024, but rising costs and slow Union Pacific approvals have pushed first service from late 2026 to 2031 or later. | Nov 13, 2026 |
| The Portal (Downtown Rail Extension) | TJPA | commuter rail | Env. Review | Mostly underground, 2.2-mile extension of Caltrain, and later California High-Speed Rail, from the 4th & King terminus beneath Townsend and Second streets into the existing trainbox under the Salesforce Transit Center, with a new Fourth & Townsend station. The project is in the FTA Engineering phase with a $3.38 billion federal share set aside, but the funding plan is not yet complete. The state awarded $750 million in November 2026, and service is forecast for 2036. | Nov 13, 2026 |
| Valley Link | Tri-Valley–San Joaquin Valley Regional Rail Authority | 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 |
| Central Subway North Beach Extension | SFMTA | light rail | Planning | Proposed extension of the T Third Line (Central Subway) north from its Chinatown–Rose Pak Station terminus into North Beach, reusing subway tunnel already bored toward Columbus Avenue and Union Street; a relaunched 2026 study is comparing a minimal one-station extension against a longer option reaching Fisherman's Wharf. | Jun 1, 2026 |
| Sepulveda Transit Corridor | LA Metro | heavy rail | Env. Review | Fully underground ~13-mile heavy-rail subway connecting the Van Nuys Metrolink Station in the San Fernando Valley to the E Line at Expo/Sepulveda, via a tunnel beneath the Sepulveda Pass serving UCLA and Westwood. | May 9, 2026 |
| San Diego Trolley Purple Line | MTS | — | Planning | Proposed ~11-mile transit line from the San Ysidro Transit Center at the US-Mexico border through National City, City Heights, and Kearny Mesa to University Town Center/Sorrento Mesa; SANDAG has not yet finalized whether the corridor will be built as subway, above-ground rail, or Trolley (light rail). | Feb 9, 2026 |
| Green Line Extension to Sacramento International Airport | SacRT | light rail | Proposed | Proposed ~12.5-mile extension of the Green Line light rail from downtown Sacramento through North Natomas to Sacramento International Airport, crossing the American River on a new bridge; SacRT is also weighing an interim bus rapid transit phase on the same corridor. | Jun 22, 2025 |
