CURRENT STATUS

Construction is underway

Tennessee announced in February 2026 that the required state right-of-way lease and enhanced grading permit had been approved, allowing The Boring Company to move forward with construction. The company later reported multiple tunnel boring machines working in Nashville and described strong rock conditions encountered during testing and excavation.

The 25-mile figure frequently associated with the project refers to the corridor authorized under the state agreement, not 25 completed miles of tunnel. Actual completed tunnel mileage, station construction and final operating infrastructure remain works in progress.

WHAT IS BEING BUILT

Tunnels, stations and operating infrastructure

The Music City Loop is more than a tunnel. The operating network requires tunnel excavation, portals, stations, vehicle circulation areas, electrical and communications systems, safety infrastructure, passenger areas and integration with properties such as BNA and downtown destinations.

Station work can progress on a different schedule from tunnel excavation. Some locations may be in agreement, design or permitting stages while adjacent tunnel work advances independently.

PERMITS & APPROVALS

What the state approval means

The February 2026 state action involved use of state-owned highway right-of-way and an enhanced grading permit. Those approvals were a major milestone because they allowed work within the state corridor to proceed. They do not eliminate the need for property-specific agreements, station design, safety review or other permits that may apply to individual portions of the network.

OPENING TIMELINE

When could passengers ride?

Tennessee officials said the first segment was expected to be operational by the end of 2026. That is a target, not a guaranteed opening date. Tunneling progress, station readiness, systems installation, testing and final operating approvals will determine when passenger service can begin.

What to watch next

1

New tunnel breakthroughs, machine deployments and construction milestones.

2

Publicly identified station agreements and permits.

3
