The Silicon Valley BART Extension will expand service by Bay Area Rapid Transit (BART) into Santa Clara County, from its former terminus at the Fremont station in Alameda County. The overall project has seven stations in three sequential phases.[1] The first phase was the Warm Springs BART extension, with the $790-million Warm Springs/South Fremont station that opened in March 2017.[2] It broke ground in 2009, and was originally scheduled for completion in 2014.

The $2.3-billion second phase, known as phase I of VTA's BART Extension or the Berryessa extension, consists of the Milpitas and Berryessa/North San Jose stations. Both are expected to open in March–September 2019.[3] The extension broke ground in 2012, originally scheduled for completion in 2016.[4] A partnership between BART and the Santa Clara Valley Transportation Authority (VTA) is building the Berryessa extension, while BART will operate and maintain the entire extension.

The $4.7-billion third phase to downtown San Jose remains unfunded. Targeted for completion in 2026, it would add three new subway stations west of Berryessa: Alum Rock/28th Street, Downtown San Jose—West Option, Diridon—North Option, and a surface station in Santa Clara.

Funding[edit]

Construction on the Warm Springs extension underway in Fremont, September 12, 2012

Santa Clara County was originally planned to be part of the BART system, but local governments did not approve. Minor service at Palo Alto near San Mateo County had also been planned originally.

In 2000, Santa Clara County voters approved a 30-year half-cent sales tax increase to fund BART,[5] which took effect in 2006. To make up for a shortfall in projected federal funding, an increase in the sales tax by 0.125 percent was proposed if additional federal funding were secured.[5][6]

The economy worsened in 2009, and the 2000 sales tax was projected to generate $7 billion—short of the originally expected $11 billion. As a consequence, the number of planned stations was reduced.[5][6] In addition, the line from Berryessa to downtown San Jose was delayed until 2026.[7]

VTA awarded $770 million to Skanska-Shimmick-Herzog in 2011 for the first phase of the Berryessa Extension (Milpitas and Berryessa/North San Jose Stations), and the federal government granted $900 million for the project in 2012. Construction began the same year.[8] It was scheduled to open in 2016.[9][10][11]

For phase II, VTA sought funding from the federal New Starts program in 2016.[10][12] A half-cent 30-year sales tax passed in the 2016 elections, to raise $6.0 to $6.5 billion with up to 25% of this (or $1.6 billion) for BART.[13] VTA also sought $1.5 billion from New Starts, and $750 million from the California Cap and Trade program.[14][15][16]

In 2018, VTA was awarded $2.6 billion for the project from the state's Transit and Intercity Rail Capital Program funded by the 2017 gas tax bill.[17]

Warm Springs Extension[edit]

As part of a separate extension by BART, the $790 million extension to Warm Springs is five miles long.[18] The original estimate was $890 million.[19] The cost of the subway segment under the lake in Fremont was reduced by 45% from the original estimate of $249 million to $136 million.[20] From south of Paseo Padre Parkway to Warm Springs station, the extension used the former right-of-way of the Western Pacific Railroad San Jose Branch, with the Union Pacific Railroad Warm Springs Subdivision running parallel.

The Warm Springs/South Fremont station opened on March 25, 2017.[21] The extension broke ground in 2009,[22] scheduled for completion in 2014.[22][23] Construction of the station began in 2011,[24] and was expected to take three and a half years.[22] However, the opening was pushed back to fall 2015,[25][26][27] to early 2016,[28] to spring 2016,[29] to summer 2016,[30] to fall 2016,[31][32] to late fall 2016,[33] to winter 2017,[34] and to spring 2017.[35] VTA's BART Silicon Valley Extension connects to the Warm Springs/South Fremont station.[1]

Berryessa Extension[edit]

Planned extension of BART into Silicon Valley

The Milpitas and Berryessa/North San Jose Stations are expected to open in March–September 2019. As of 2018, the project had been delayed three years.[3] The opening was pushed back from 2016,[4] to late 2017, June 2018,[36][37] fall 2018,[38][39] and January–March 2019.[40]

The line extends south from Warm Springs to Milpitas station (originally to be called "Montague Station"), with a pedestrian bridge to the VTA's Montague light rail station near the Great Mall of the Bay Area, and then on to Berryessa station. A proposed infill station in downtown Milpitas, Calaveras station, has been deferred until the city secures funding.[5] Like the Warm Springs Extension, the Berryessa Extension uses the former San Jose Branch, with the Warm Springs Subdivision running parallel for part of the length.

In 2009, VTA proposed to extend the line as far as they could afford (Berryessa) until further funding could be obtained.[5] In 2009, the MTC also changed its rules allowing bridge and HOT lanes tolls to be used for transit projects, such as BART expansion, VTA light rail extensions, bus or ferry operations.[5]

A local industrial park sued in 2011, without success, on environmental grounds claiming that the extension would reduce vehicular access.[41]

The capacity of existing rolling stock is not adequate for full service on the extension. Full service depends on the on-time delivery of 35 new train cars, but the delivery has been delayed.[42]

Downtown San Jose/Santa Clara extension[edit]

A $4.7-billion final leg is proposed to downtown San Jose, first to the proposed Alum Rock/28th Street station on the city's "east side", connected by a tunnel under Santa Clara Street to a proposed Downtown San Jose Station, which would be an interchange station to VTA lightrail lines.[5] Like the Berryessa Extension, it would be built by VTA, but operated by BART. The original proposal had separate Civic Plaza/SJSU and Plaza de César Chávez stations, but these were consolidated into a single station to cut costs.[5] The line would continue to the San Jose Diridon station (transfer point to Amtrak, Caltrain, Altamont Corridor Express, VTA Light rail and bus, and the planned California High Speed Rail system), and the proposed BART subway station would be called "Diridon". It would then continue to the proposed Santa Clara Caltrain Station.[1]

Originally the entire extension from Fremont to Santa Clara was proposed as one megaproject, but lower than expected federal funding and sales tax revenue reduced the scope of the project. It was divided into two phases, to Berryessa and downtown.[5] After funding was secured for the first phase in March 2012, VTA began looking for $2.4 billion to close the remaining funding gap for the projected $4.7 billion cost of the second phase of the proposed extension to downtown San Jose and Santa Clara.[43] Completion is expected in 2026,[44][45][46] pushed back from 2025.[47][12]

In late 2017, VTA and BART disagreed on the tunnel design, single- or dual-bore. A single bore, 45-foot-wide (14 m), has two tracks stacked above one other. The twin-bore design would have separated the tunnels horizontally, each 20 feet (6.1 m) wide. Although BART has dual bores in other parts of its system, VTA preferred a single bore to reduce construction-related disruption to city streets, shorten the construction schedule, and avoid cut and cover construction in Santa Clara Street for station boxes. BART preferred dual bores, to cut construction cost, and standardize the procedure for emergency evacuations. The single-bore design is newer, less tested in the US.[48][49] Local businesses, cities and VTA were lobbying for a single bore in 2018.[50] The design decision was postponed for three months;[51] at the end of March, BART and VTA reached agreement on a single bore.[52][53]
