Nashville is moving forward with an innovative mobility project that could transform the way travelers reach the city’s main gateway. The Metropolitan Nashville Airport Authority has signed a letter of intent with The Boring Company to develop the Music City Loop, an all-electric underground transit system connecting Nashville International Airport to key destinations across Nashville. Designed as a high-speed tunnel network operating dedicated electric vehicles, the system aims to reduce road congestion while offering passengers a fast and reliable way to reach the airport. Airport CEO Doug Kreulen says the initiative reflects the airport’s commitment to innovation as passenger numbers continue to grow rapidly.
The project is also notable for its financial model. Under the proposed agreement, all design, construction, and operational costs will be covered by The Boring Company, meaning no capital investment from the airport or taxpayers. Over the 50-year term, the airport authority expects the partnership to generate significant revenue through license and passenger pick-up fees. Fully electric and zero-emission, the Music City Loop is intended to remove millions of car trips from local roads while supporting the airport’s long-term expansion plans, which could see annual passenger numbers rise to 40 million at Terminal I and eventually 70 million with a future Terminal II.
