A couple of things come to mind about this project. How deep can someone bore under Miami before they reach the water level and can it be done without weakening the substructure of the earth. Back when the Metro was constructed in Washington DC, the subway tunnels were dug under the existing buildings. I was working near a lot of the tunneling and it was pretty cool job. No buildings collapsed, the metro opened and was a great way to travel between VA, DC, and MD. Of course, being new, it was clean and efficient … and safe. Today, probably not as much.
Miami Mayor Francis Suarez had a phone call with Elon Musk on Friday about digging a tunnel underneath Brickell Avenue and Biscayne Boulevard to alleviate traffic.
Following the phone call, the Miami Herald spoke with Suarez about the Musk-owned Boring Co. building a $30 million tunnel under the Brickell Avenue Bridge. He said the tech billionaire told him the tunnel could be built in six months.
- “For him, it’s not about the money, it’s about creating a solution, creating something that creates happiness and prosperity to the people,” Suarez said.
Suarez said the tunnel would only be accessible to electric vehicles because a major cost-savings of the tunnel is the lack of ventilation systems. He said the call lasted about 30 minutes.
- “I think we have a unique opportunity to create a signature project, not just for Miami, but for the world,” Suarez said in a video statement on his Twitter account.
Musk has also spoken with Gov. Ron DeSantis and Miami-Dade County Mayor Daniella Levine Cava about the project.
Suarez said the next step for him is to speak with DeSantis about the idea considering Miami-Dade County transit officials have already considered building a more expensive tunnel under the city.
Already, Boring has found success in completing a third of a mile transport tunnel beneath the Las Vegas Convention Center at the cost of $52.5 million.
Last week, San Bernardino County Transportation Authority in Southern California approved plans to connect a train station in Rancho Cucamonga, California, to Ontario International Airport with a Boring tunnel.
… and good luck to Miami officials, who believe Musk can deliver them a tunnel under budget and in six months. Musk has been notorious for overstating promises.
We’re still waiting for the million robotaxis Musk promised on the road by 2020.
