U.S. Department of Transportation (DOT) Secretary Sean Duffy toured the Music City Loop construction site last week, hailing the privately-funded project as “critical infrastructure” seeking to “meaningfully improve” the lives of those traveling around Nashville.
In a press release, the DOT said the Federal Highway Administration worked with state and private-sector partners to accelerate the project’s approval timeline by 83 percent, allowing construction to begin significantly faster than under traditional federal review processes.
The department also confirmed that the $200 million project remains on schedule to open in the spring of 2027, first connecting downtown Nashville with Nashville International Airport in approximately 10 minutes.

“For too long, we’ve let our bloated bureaucracy gum up critical infrastructure projects that could meaningfully improve the lives of the traveling public,” Duffy said in a statement following his visit to Nashville. “This project is further proof that those days are over, and America is building again.”
“By empowering innovators like The Boring Company, we are creating good-paying jobs that will deliver big, beautiful infrastructure for American families and businesses nationwide,” Duffy added.
Tennessee Governor Bill Lee also praised the project, calling it an example of how public-private partnerships can deliver transportation improvements while strengthening the state’s economy.
“The Music City Loop demonstrates what’s possible when government leverages private-sector partnerships to pursue opportunities we couldn’t achieve on our own, and we look forward to continuing to work in partnership with the Trump Administration to keep Tennessee at the forefront of transportation innovation,” Lee said in a statement distributed by the DOT.
Following Duffy’s visit, The Boring Company thanked the transportation secretary on social media.

Duffy’s visit to Nashville comes as construction activity for the tunneling project continues to ramp up beneath the city.
Earlier this month, The Boring Company announced that its first tunnel boring machine, Prufrock-MB1, has been excavating since April while receiving continuous upgrades to improve tunneling speed and reliability.
In its latest construction update, the company announced that commissioning of Prufrock-MB2 has now been completed, including final testing at 11 revolutions per minute, clearing the machine to begin mining. The company also revealed that Prufrock-MB3 is scheduled to ship to Nashville in August.
The initial downtown-to-airport route is expected to serve as the first phase of a broader underground transportation network under Nashville.
The Boring Company has previously outlined plans to expand the Music City Loop with future connections to destinations including the Gaylord Opryland Resort & Convention Center, the Grand Ole Opry, and eventually additional residential, entertainment, and commercial hubs across the Nashville area.
The company has so far announced the first residential stations for the tunnel system, with the Prime, Alcove, and Paramount towers in downtown Nashville set to receive exclusive access through dedicated elevators connecting residents directly to the tunnel network.
