The project aims to create a 10-mile tunnel that would allow travelers to get from downtown Nashville to Nashville International Airport in about eight minutes.

The Boring Company, yet another of Elon Musk’s companies, has been hired to dig car tunnels underneath Nashville. The State of Tennessee is looking for innovative ways to facilitate transportation and decided to give the revolutionary concept a whirl.

Elon Musk's Boring Company will build a privately funded high-speed tunnel, the Music City Loop, connecting Nashville International Airport to downtown. While state officials and the U.S. DOT secretary expressed enthusiasm, Nashville's mayor raised operational concerns and some residents voiced skepticism.
