Boring Company proposes $34 million airport tunnel license as Nashville weighs a long-term transit agreement

A proposed long-term airport transit deal moves into focus

Elon Musk’s tunneling firm, The Boring Company, has proposed a $34 million agreement tied to a planned underground transit connection between downtown Nashville and Nashville International Airport (BNA), a project branded as the “Music City Loop.” The proposal is structured around a long-term operating license that would govern how the system is run and monetized once built.

The tunnel concept, announced in late July 2025, envisions electric vehicles carrying paying passengers through dedicated underground lanes beneath state-controlled roadway corridors. Public statements surrounding the project have described the initial segment as roughly 10 miles in length, with an advertised end-to-end travel time of about eight minutes. Project timelines discussed publicly have ranged from “as early as fall 2026” for initial operations to a later opening target that extends into 2027 as permitting progresses.

How the $34 million proposal fits the project’s financing

State leaders and the company have said construction and operations would be privately funded, with riders paying a fare. The $34 million figure relates to the right to operate the service over a multi-decade term, rather than a public construction subsidy. Separately, estimates discussed publicly by company representatives have placed construction costs in the “few hundred million” range, with a commonly cited estimate of roughly $240 million to $300 million for the initial build.

The financing model makes future ridership and fare revenue central to the project’s viability. While the company has indicated fares would be competitive with other transportation options, specific pricing has not been publicly finalized.

Approvals, property access, and the current status

In the days after the 2025 announcement, the State Building Commission approved a no-cost, temporary lease of a state-owned downtown parking lot on Rosa Parks Boulevard for use as a staging area connected to tunneling work. Meeting materials and subsequent coverage described safeguards requiring restoration of the site if the project does not proceed.

The project’s path forward still depends on multiple permits and approvals. By January 2026, public reporting indicated dozens of permits were expected, with a portion approved and others pending. The company has publicly stated it is prepared to begin tunneling once remaining approvals are in hand.

Key questions raised by supporters and critics

• Governance and oversight: Metro Council members have advanced a symbolic resolution opposing the project, citing concerns about transparency and local engagement, though the resolution would not stop construction.

• Safety and labor practices: The Boring Company’s safety record has drawn scrutiny in other markets, including regulatory enforcement actions tied to workplace conditions during tunnel construction.

• Engineering risk: Middle Tennessee’s geology and groundwater conditions have been cited by industry observers as factors that can complicate tunneling, with potential impacts on schedule and cost.

What happens next will be shaped by final contract terms, remaining permits, and the structure of long-term operational oversight at the airport and along the route.

If executed, the proposed agreement would formalize a privately financed, fare-based alternative for airport travel that would operate alongside existing road and transit options, while committing Nashville-area stakeholders to a new type of long-duration infrastructure partnership.
