Transportation officials in San Jose may take its "long-awaited" BART extension back to the drawing board, as tariffs, the war with Iran and rising labor prices cause the price of the project to swell, Rachel Swan writes for the San Francisco Chronicle.

Officials originally estimated the price of the extension at $12.7 billion; they have not released an updated price. The Valley Transportation Authority is looking at “adaptive” options for the BART extension, Swan reports.

The San Francisco Chronicle reports:

Exactly how VTA engineers and planners will scale back or retool the project is unclear. During the meeting, committee members discussed the possibility of reordering construction of stations. A couple speakers broached the idea of switching to “technologies” other than BART to save money and finish the project by 2037. This could mean replacing the heavy Bay Area rail system with a light rail train or autonomous tram, like the one to Oakland San Francisco Bay Airport.
