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.

The Boring Company is bringing an underground, high-speed tunnel to Nashville. It's Elon Musk's latest business dealing in Tennessee. Here's what to know

Construction of the 10-mile Music City Loop is expected to begin immediately after approvals, with the project potentially operational as soon as fall 2026.

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.

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.

It's called the Music City Loop, and the project marks Musk's latest effort to bolster his budding business empire in Tennessee. His artificial intelligence startup xAI, the parent of social media platform X, is building data centers and a power plant in Memphis, on the western side of the state.
