Elon Musk’s Miami Tunnel Plan Is Filled With Holes – Curbed

It’s the sinkhole capital of the United States, to start.

Last weekend, Elon Musk claimed that he’d had a conversation with Florida Governor Ron DeSantis about his Boring Company project, which builds very short, very small tunnels for cars. “Cars & trucks stuck in traffic generate megatons of toxic gases & particulate, but @boringcompany road tunnels under Miami would solve traffic & be an example to the world,” he tweeted. “If Governor & Mayor want this done, we will do it.” This was at 4 a.m. Miami time, but almost immediately, the city’s mayor, Francis Suarez, tweeted his approval: “Count me in,” he said, calling Musk’s plan a “no brainer.”

Now before we write this off as yet another example of Musk’s perpetual grift of making empty promises to city leaders that are amplified by his 42.6 million followers, let’s consider that there might be a reason why Miami doesn’t have a subway. Or why many of its homes are built without basements. Or why the city has already spent hundreds of millions of dollars just to make its streets navigable to cars today — building a pump system to mitigate the flooding Miami now faces even when no storms are on the horizon.

“It’s the sinkhole capital of the United States, let’s start from there,” says Mika McKinnon, a field geophysicist and disaster researcher based in Vancouver. The ground beneath Miami is a highly dissolvable limestone karst that’s filled with cavities and caverns just like the sea floor. “If you want to have a tunnel, you need to pump the water out of the tunnel as you go,” she says. “And when you hit a cave or you puncture a cavity, it changes the pressure. It’s like popping your car into neutral while you’re on the highway.”
