Elon Musk is pushing to build a massive 6.2-mile underground tunnel to ferry Tesla vehicles and their passengers in the traffic-clogged area of North Miami Beach.

Musk's Boring Company are currently considering the Hard Rock Stadium and Florida International University's Biscayne campus as hosts for the proposed transit tunnel, which will run underneath Miami-Dade, according to the Miami Herald.

The tunnel, which would initially see Tesla vehicles carrying as many as 7,500 passengers per hour with an eventualy goal of as many as 15,000 per hour, would have drivers passing underneath State Road 826 East from Northwest 2nd Avenue to Northeast 35th Avenue. 

The 'rough' estimated cost for the project sits at between $180 million and $220 million, and is expected to be completed in a 36-month construction time frame, according to Boring. 

A loop to Hard Rock would stretch three additional miles, while the FIU-Biscayne spur would run about 1.8 miles. 

The idea, which is also being considered in Fort Lauderdale and Miami, is designed to tackle traffic and gridlock issues. 

Critics of the plan only have to look as far as Las Vegas, where Musk's Vegas Loop - a 1.7-mile track for manual driven Teslas to drive beneath the city's convention center at top speeds of 40 miles per hour - where users have expressed concerns over getting stuck in the tunnel and other safety issues.
