Once completed, the “Tesla in tunnels” system will ferry people from the airport to downtown in around eight minutes.

Nashville officials on Monday announced a massive public transportation partnership with Elon Musk’s The Boring Company to alleviate the city’s significant traffic congestion problems for travelers bound to the airport.
