Construction at the Music City Loop site, March 2026

The Boring Company has provided a blog update regarding the Music City Loop, with a second tunnel-boring machine undergoing final testing before being deployed this month.

The Elon Musk-owned company is constructing two one-way tunnels to make up a 19-mile route connecting downtown Nashville (near the Tennessee State Capitol) and the Nashville International Airport.

Using what The Boring Company calls Prufrock-MB1, tunneling began on the first tunnel earlier this spring. Rock is removed from the under-construction tunnel via a continuous belt conveyor system.

The next tunnel will be undertaken with the company's Prufrock-MB2 and will also launch from a worksite located at 637 Rosa L. Parks Blvd.

“Lessons learned from the launch and operation of MB1 are already being applied to MB2 to improve efficiency and prepare the machine for launch,” The Boring Company posted on its website Monday.

Recently, the Metropolitan Nashville Airport Authority unanimously approved (8–0) the future Music City Loop station at Nashville International Airport, with design and permitting currently underway.

Users of the Music City Loop will take Teslas to and from downtown and BNA.

Local development company Giarratana LLC announced in early May the Music City Loop will serve residents in its trio of Church Street towers. The private station will be located in the parking garage of Prime, a 38-story mixed-use high-rise with an address of 805 Church St. Residents of Alcove, located at 900 Church St. will also have access to the station, as will the future residents of Giarratana LLC’s 60-story 750-foot-tall Paramount, under construction at 1010 Church St.

Tony Giarratana, president of his eponymously named company, says users of the Music City Loop will access the station via an elevator.

The Boring Company has said it has held discussions with more than 230 community, educational, nonprofit and professional organizations and participated in approximately 120 in-person volunteer events, according to the update. The company also says it has responded to more than 170 inquiries submitted via email.

With a cost between $240 million and $300 million (which Boring says it will cover), Music City Loop is expected to open in 2027.
