- Elon Musk's The Boring Company has submitted plans to build a 6.2-mile tunnel transit system in Miami.
- A proposal for the North Miami Beach Loop, seen exclusively by Insider, show it would have seven stations.
- City commissioner Michael Joseph told Insider the loop would help relieve traffic congestion.
Elon Musk's The Boring Company has submitted a proposal to construct a 6.2-mile underground transit system in Miami, Insider can reveal.
The North Miami Beach Loop would ferry Tesla vehicles between seven stations along State Road 826, between the Golden Glades Transit Center and Sunny Isles Beach at Newport Pier, according to the proposal, seen by Insider.
The Boring Company estimated that the loop would initially be able to carry more than 7,500 passengers per hour, and could be scaled to carry more than 15,000 per hour.
The estimated cost of the project was put at $185 million to $220 million, per The Boring Company's proposal. It predicts that construction would take fewer than three years if the permitting process was expedited.
The proposal also recommends several potential extensions to the 6.2-mile North Miami Beach Loop, including a 3-mile connection to Hard Rock Stadium and a 1.8-mile link to Florida International University's Biscayne Campus.
"We have a lot of traffic congestion and this would be a way of alleviating a great deal of that traffic," North Miami Beach commissioner Michael Joseph said in an interview with Insider.
Commuters and visitors would benefit from having the tunnel network connecting the city center to the beach, Joseph said.
He said the estimated cost per mile of the North Miami Beach Loop would be "a fraction of what is seen in other types of mass transit projects proposed in South Florida, while the construction would not be as disruptive to the local economy."
Joseph said the city was trying to obtain funding for the loop, and was seeking finance from regional, state, and federal governments.
The Boring Company didn't immediately respond to Insider's request for comment.
In March 2021, Joseph told Insider's Grace Kay that he had spoken to The Boring Company several times about an underground transit system, and had submitted a working paper to the tunneling firm for review.
The North Miami Beach Loop wouldn't be as extensive as the Vegas Loop, a 29-mile tunnel system that is under construction by The Boring Company. The Vegas Loop is expected to connect Teslas to more than 50 stations across Las Vegas, per The Boring Company's website.
