Estimated BART costs go up again

If you thought $12.2 billion was astronomical for a 6-mile, 4-station extension... I don't have good news. The Federal Transit Administration now thinks the project will cost $12.8 billion and the timeline will be extended to 2037. Reasons behind the cost increase are primarily the volatility of labor and supply costs.

13 years is a long time. We might be living in a post-AGI word (artificial general intelligence) where costs for design and construction could be significantly lower than expected or perhaps new transit options will arise that were not feasible in the past. While I have voted for the BART extension every single time, the consistent increase of cost estimates and timeline adjustments is concerning.
