Traditionally, tunnels have costed up to $1 billion per mile in the US. With the @boringcompany that figure is closer to $10 million per mile. Incredible.

The Boring Company: Encore project (Prufrock-2) took approx. 10 weeks with the starting point of "arrive at empty parking lot." Mobilization, launch, tunneling (2350 ft), and retrieval. Good step towards building infrastructure projects in a matter of weeks versus years. https://t.co/KF548cvmsX
