Committee advances bill to create statewide subterranean transportation authority after extended debate

A Tennessee House committee advanced legislation to establish a statewide authority for permitting, planning and constructing subterranean transportation projects, provoking an extended clash over local control and emergency response.

Representative Garrett, sponsor of House Bill 2450, told the Government Operations Committee the bill would create a consistent regulatory framework to enable projects that could move people “from Memphis to Mountain City” and reduce traffic and emissions. He said the authority would include a governor’s council and a permitting process to coordinate state and local interests and that operators would have to seek local approvals where projects touch municipal rights‑of‑way.

Opponents pressed on a range of issues. Representative Clement argued the bill would limit local regulation over station entrances and portals, give the authority broad condemnation powers and grant the operator control over emergency responses in tunnels; he warned, “This is a threat to public safety,” and said the measure risks allowing private operators to exercise unchecked authority over local property and services.

Garrett and other supporters rejected that characterization. Garrett described the criticisms as “political hyperbole” and said the bill does not take private property or remove local input; he called the technology a potential game changer for statewide mobility and argued it could generate new economic activity and state revenue through fees and increased commerce.

Committee members asked detailed procedural questions about indemnification and remedies for local infrastructure damage. The sponsor said the bill includes indemnification language requiring an operator to repair or reimburse damages caused by construction and that the authority would be subject to statutory oversight and a governor’s council.

The committee also debated how the authority would coordinate emergency services and whether local 911 responders would retain ability to act without delay. Supporters said examples such as airport and megasite authorities demonstrate how public safety and local coordination can be preserved; opponents contended the draft gives too much discretion to an unelected entity.

After multiple rounds of questioning, the committee voted 8–4 to advance HB 2450 to Finance, Ways and Means. The sponsor said the next steps would include rulemaking and interagency coordination if the bill continues to move through the Legislature.
