An underground transit system project has been announced for Nashville, Tennessee. On Monday, Tennessee Gov. Bill Lee announced The Boring Company intends to build the Music City Loop, a private transportation system that would transport travelers underground from downtown Nashville and the convention center to Nashville International Airport.

Somehow, Elon Musk keeps convincing cities to allow him to dig under them. The latest locale to give The Boring Company the rights to displace dirt directly under their feet is Nashville, Tennessee, which announced an agreement this week to allow Musk’s firm to build a 10-mile “loop” that will connect the city’s airport and convention center—an arrangement that has modestly improved traffic flow in Las Vegas while turning the city into a laughingstock of the infrastructure design community.
