Yes, the Nashville tunnel project is real and construction is underway—but “Tesla tunnel” is shorthand that obscures who is building it and how it will work. The Music City Loop is being developed by The Boring Company, founded by Elon Musk. It is planned as a privately funded, fare-based underground service connecting Nashville International Airport (BNA) with downtown Nashville, including the Music City Center and Lower Broadway area.
The system is expected to use dedicated Tesla Model Y and Model X vehicles operated initially by trained Loop drivers. It is not a tunnel for ordinary Tesla owners to drive through, and the current operating plan does not describe fully autonomous vehicles.

What is the Music City Loop?
The Music City Loop is a proposed underground transportation system designed to move passengers between BNA and central Nashville. The Boring Company describes it as a “Loop” rather than a conventional subway or light-rail system.
Passengers would board small electric vehicles at stations and travel directly through dedicated tunnels. The initial plan calls for:

- Revell Model Kit #14590, Skill Level 4, Contains 57-Parts, Recommended for ages 12 and up
- Classic “squarebody” cab styling. Detailed Captain Hook wrecker body includes a telescoping boom with a tow swing.
- Push bumper, roof-mounted air horns, and twin CB antennas. All-new decal sheet with authentic GMC Captain Hook truck graphics.
- Opening hood shows off the 350-cid V-8 engine detail. Integrated TwinSonic light bar and dual rear wheels.
- Molded in white and clear with soft black tires. Paint and glue required(not included).
- Tesla Model Y and Model X vehicles;
- trained Loop drivers during the initial operating period;
- fare-based passenger service;
- direct trips without the intermediate stops typical of a subway line; and
- private ownership and operation by The Boring Company.
Passengers are expected to buy tickets online or through an app, or scan a QR code at a station. The company has not disclosed a Nashville fare in the official FAQ reviewed for this article.
That missing fare is important. A nine-minute airport trip could be attractive to travelers, but the service’s practical value will depend on whether the price competes with rideshare, taxis, buses and parking—not only on how quickly the vehicle moves underground.
Who is actually building it?
Tesla, Inc. is not the developer identified in the project documents. The developer and intended operator is The Boring Company, the tunneling business founded by Musk. Tesla vehicles are part of the proposed fleet, which is why headlines often call the project a Tesla tunnel.

The vehicles are also not currently described as autonomous Tesla taxis. The company’s official FAQ says trained Loop drivers will operate the initial service.
Where will the tunnel run?
The core corridor is intended to connect:
- Nashville International Airport, or BNA;
- downtown Nashville;
- Music City Center;
- Lower Broadway; and
- the West End Avenue area.
The company describes the airport-to-downtown connection as almost 10 miles and estimates a trip of approximately nine minutes. Its draft project material says vehicles may travel at speeds of up to 70 mph inside the tunnel, but that figure should not be confused with an average end-to-end journey time. Boarding, station access, acceleration, deceleration and unloading all affect the actual trip.
The broader alignment shown in project material should also be separated from the initial airport corridor. A proposed larger network is not the same thing as a completed or fully approved citywide system.

According to The Boring Company’s official updates, yes. The project was announced on July 28, 2025. The company initially said construction was expected to begin in fall 2025, with initial segments potentially operating as soon as the fourth quarter of 2026.

- over 300 super-detail parts
- first time available in original illustrated packaging since its first release in the early 1970s

The reported milestones are:
- July 28, 2025: The Music City Loop was announced.
- February 2026: The company said its first Prufrock tunnel-boring machine began tunneling.
- February 25, 2026: The company cited execution of a Tennessee Department of Transportation tunnel permit and lease agreement.
- June 1, 2026: The company said the first machine was tunneling, a second machine had arrived and was being commissioned, and a third was being built.
- July 16, 2026: The official project page was listed as updated.
- Q4 2026: This remains the original “as soon as” target for initial operations—not a guaranteed opening date.
The company’s projects page lists Music City Loop as “Under Construction.” That means tunneling has begun; it does not mean the airport-to-downtown route is complete or that passenger service is definitely starting in 2026.
The company’s June update says 37 of the 45 approvals required for the broader project had been obtained before tunneling began. It also says the TDOT agreement authorized up to 25 miles of tunnel within TDOT right-of-way. That is an authorization figure, not a claim that 25 miles have already been built.
How is the project being funded?
The Boring Company says the Music City Loop is 100% privately funded and that construction and operation will use no taxpayer dollars. The company also says passengers will pay fares when the system operates.
For residents and taxpayers, however, “privately funded” should be understood precisely. Public agencies still have roles involving permits, rights of way, leases, airport arrangements, easements and regulatory review. Those arrangements may not be direct construction funding, but they are part of the project’s public context.
The full construction cost and long-term financing details have not been clearly disclosed in the official material reviewed. That makes the project different from a conventional publicly financed transit project, but it does not eliminate questions about public access, oversight and the value of using public rights of way.
For travelers, the most immediate financial question is the fare. Until The Boring Company publishes a price, it is impossible to determine whether the Loop will function as an affordable transit option, a premium airport shuttle or something in between.
What approvals has it received?
The Boring Company says several important approvals and agreements are in place:
Recommended Free Tools
- TDOT’s tunnel permit and lease agreement were executed on February 25, 2026.
- The Metropolitan Nashville Airport Authority approved an airport connection and station by an 8–0 vote, according to the company.
- The Music City Convention Center Authority approved a downtown tunnel easement by an 8–0 vote, also according to the company.
The airport authority’s own announcement is available through Nashville International Airport.

- Hood tilts forward to show detailed turbocharged six cylinder diesel engine
- Chrome plated simulated alloy wheels, dual exhaust stacks, roof mounted horns and mirrors with antennas
- Molded in white and clear with chrome plated parts and soft black tires
- Decals with optional stripes or custom graphics - Kenworth markings and license plates
- Includes illustrated instructions
These approvals should not be summarized as unanimous approval by Nashville government. The Metro Council separately adopted a resolution criticizing the project and raising concerns about consultation, transparency, safety, environmental review, accessibility and its relationship to Nashville’s broader transit plans. The Metro Council legislation records those objections.
Why is Nashville’s government divided?
The dispute is not simply “Nashville versus Elon Musk.” Different institutions control different parts of the project.
- The Boring Company: developer, intended private owner and operator.
- TDOT: involved in the state-controlled transportation right of way and tunnel agreement.
- Federal agencies: involved in applicable federal transportation and review processes.
- Nashville International Airport authority: responsible for approval related to the airport connection and station.
- Convention center authority: involved in the downtown easement.
- Metro Council: Nashville’s local legislative body, which has expressed opposition and concerns.
This division explains how construction could advance even while Metro Council members argue that local government and residents have not had enough influence over the project.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Critics’ concerns include whether emergency procedures are sufficiently documented, how accessibility will work, how geology and flooding risks were assessed, whether the project fits Nashville’s long-term transit strategy and whether the public is receiving enough financial and operational information.
How fast will it be?
The company estimates approximately nine minutes between BNA and downtown. It has also described vehicle speeds of up to 70 mph in the tunnel.
Those numbers are projections, not Nashville operating results. A realistic comparison with a car, bus or rideshare should include the time needed to reach a station, wait, board, travel, exit and reach the final destination. The Loop could be especially attractive for passengers traveling between a downtown station and the airport, but the total door-to-door advantage will depend on station locations and access.
Is it a subway?
Not in the conventional sense. The Loop uses road-style electric vehicles rather than trains. That creates potential advantages, such as direct trips and flexible vehicle dispatch, but it also raises different capacity and operating questions.

The available Nashville project material does not provide a definitive peak passenger-capacity figure. That is one of the most important unanswered questions. A fast system is not automatically a high-capacity system, and an airport connector may not solve neighborhood-to-neighborhood transportation problems.

The Boring Company’s original announcement says the system will meet or exceed NFPA 130, a fire and life-safety standard associated with fixed guideway transit and passenger rail systems.
That is a design and compliance commitment, not evidence of a completed safety record. Readers should still look for details about ventilation, fire detection, emergency exits, communications, rescue access, evacuation times, independent inspection and the agencies responsible for enforcement.

The company’s environmental assessment says the evaluated design would produce no meaningful impacts across the reviewed resource categories and could have positive effects on transportation, air quality, greenhouse-gas reduction and economic growth.
Those are company-published assessment conclusions. They should be weighed alongside the Metro Council’s requests for more information about geology, flooding, environmental effects and public review. “Zero emissions,” where used to describe the project, should also be understood as referring to vehicle operation—not necessarily the full lifecycle emissions of excavation, construction and electricity generation.
What could the project improve?
If the system opens and performs as projected, it could provide:
- a faster airport-to-downtown option;
- an additional choice for tourists, airport workers and downtown employees;
- electric vehicle operation without adding another surface road;
- potentially lower surface congestion if it attracts substantial demand; and
- a privately financed alternative to a conventional public rail project.
These are potential benefits, not demonstrated Nashville results. The project has not yet established its fare, reliability, passenger capacity or operating schedule.
What are the main trade-offs?
| Question | What is known | What remains uncertain |
|---|---|---|
| Price | Passengers will pay fares. | The fare has not been disclosed. |
| Speed | The company estimates about nine minutes from BNA to downtown. | Actual door-to-door travel time and average operating speed. |
| Coverage | The core plan connects BNA with central Nashville. | Whether and when a larger network will be built. |
| Capacity | Small Tesla vehicles are planned. | Peak passengers per hour and maximum vehicle frequency. |
| Accessibility | Accessibility is among the issues raised by local officials. | Final station, boarding and emergency-access details. |
| Reliability | Tunneling is underway. | Uptime, maintenance performance and disruption procedures. |
| Public cost | The company says construction and operation are privately funded. | The full financial terms of public rights-of-way, leases and agreements. |
What remains unknown before riders can rely on it?
- The exact fare and payment rules;
- a confirmed passenger-service opening date;
- operating hours and service frequency;
- peak passenger capacity;
- the final number and location of stations;
- accessibility specifications;
- emergency evacuation procedures and independent inspection arrangements;
- the final route and construction schedule; and
- whether the airport connector will expand into a broader Nashville network.
Those gaps matter especially to people making financial or commuting decisions. A projected nine-minute ride cannot yet be treated as an available alternative to a car, rideshare, bus or parking plan.
Bottom line
Nashville’s “Tesla tunnel” is no longer merely a proposal: The Boring Company says tunneling began in February 2026, and the project is listed as under construction. But it is not a completed subway, Tesla, Inc. is not the identified builder, and the original fourth-quarter 2026 target is not a guaranteed launch date.
The most accurate description is a privately funded, fare-based underground passenger project developed by The Boring Company, using Tesla vehicles and initially trained drivers, with a planned connection between BNA and downtown Nashville. Its success will depend on more than tunneling speed: fares, capacity, accessibility, safety oversight, reliability and public accountability will determine whether it becomes useful transportation or primarily a premium airport connection.
