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

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.

Elon Musk’s Boring Company plans a privately funded tunnel in Nashville to connect downtown and the airport, promising eight-minute Tesla rides underground.
