More than 40 stations are now in various stages of planning and design for the Music City Loop as The Boring Company continues expanding the scope of its privately funded underground transportation network beneath Nashville, according to the company’s latest construction update.
In its sixth official Music City Loop blog post, The Boring Company said last week it is continuing to work with property owners to advance station development along the tunnel alignment while pursuing additional partnerships for future stations.
The update highlighted several milestones reached in recent months, including unanimous approval by the Metropolitan Nashville Airport Authority for a station at Nashville International Airport and unanimous approval by the Music City Convention Center Authority for a downtown tunnel easement. The company also pointed to previously announced agreements for stations serving the Prime, Alcove, and Paramount residential towers, as well as the JW Marriott in downtown Nashville.
As planning for stations continues, tunneling operations are also expanding.
The Boring Company announced that Prufrock-MB2, the project’s second tunnel boring machine, has officially launched after completing commissioning at the Lot 16 construction site.
Similar to the project’s first machine, Prufrock-MB1, MB2 will spend its first several weeks undergoing testing and upgrades while excavation continues. A second vertical cassette used for continuous rock removal is also now operational to support the new machine.
Meanwhile, the company said Prufrock-MB1 has continued making what it described as “steady progress,” with consistent week-over-week performance improvements while maintaining safe tunneling operations.
The company also announced that Prufrock-MB3, which is being constructed in Bastrop, Texas, remains on schedule to arrive in Nashville in September and will incorporate lessons learned from the first two machines, making it “significantly more efficient from day one.”
According to the update, geological conditions have remained favorable throughout construction, with regular core sampling showing rock compressive strengths of approximately 14,000 pounds per square inch.
The company also highlighted its continued community engagement, noting it has hosted more than 50 site tours for residents, business owners, students, community leaders, elected officials, and regulatory agencies.
Among those who recently toured the construction site were U.S. Transportation Secretary Sean Duffy and Governor Bill Lee.
The first phase of the approximately $200 million Music City Loop is expected to connect downtown Nashville with Nashville International Airport in roughly 10 minutes when it opens in spring 2027, with future expansions planned throughout the city.
