Elon Musk spoke with Miami’s mayor about building a $30 million tunnel under the city

Miami appears to be one step closer to having a system of Elon Musk-built tunnels running under the city. 

Musk and Miami Mayor Francis Suarez spoke Friday about the potential for congestion-reducing tunnels built by the entrepreneur's Boring Company, a startup that wants to build networks of underground roads for electric vehicles. 

"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 posted to Twitter following the call. "[Musk is] focused on trying to deliver a project that will have the maximum utility for our residents for the least amount of money. The order of magnitude in terms of cost savings is significant."

According to Suarez, Musk said the tunnel would cost around $30 million and would take six months to complete. In 2018, Miami-Dade County transit officials had estimated that the project “” which seeks to create a two-mile-long tunnel under the Miami River “” would cost nearly $1 billion and would span four years, The Miami Herald reported.

Musk expressed interest in boring tunnels under Miami last month, when he tweeted: "Cars & trucks stuck in traffic generate megatons of toxic gases & particulate, but @boringcompany road
