and Willow station (near Facebook headquarters, close to Willow Road and CA-84); in the East Bay, the proposed station is Newark with potential extensions to Union City (at the existing BART station) via Fremont-Centerville and a spur line to Ardenwood (near CA-84 and Ardenwood Road). In 2019, Facebook proposed investing $1 billion for the project. The plan was for construction to begin as early as 2022 and finish by 2029. On June 2, 2019, a brush fire that authorities suspected was arson spread to the wooden trestle on the eastern approach near the Newark Slough Bridge. Like the prior 1998 fire, firefighters had difficulty reaching the relatively remote location. After the coronavirus pandemic came to the United States in 2020, the vast majority of Facebook staff began working virtually, and Facebook announced it was reassessing its commitment to the project. In 2020–2021, Facebook wound down their involvement. Considering financial difficulties encountered in 2022 for Meta (the rebranded parent company of Facebook), it is considered unlikely that they will return to the project. Commuter automobile traffic across the Dumbarton Highway Bridge had exceeded its pre-pandemic levels by September 2022, suggesting that a need remains in the area for more commuter options.
