Tennessee State Building Commissioners unanimously passed a proposal to gift a no-rent lease to Elon Musk’s The Boring Company during a special meeting July 31.

Tennessee Governor Bill Lee says the Nashville tunnels will come at “zero cost” to taxpayers, and will instead be “entirely privately funded” by The Boring Company and its partners. Once completed, the “Tesla in tunnels” system will ferry people from the airport to downtown in around eight minutes.
