"Hawthorne leaders have signed off on construction of tech tycoon Elon Musk’s first test tunnel for electric vehicles"

DB:

The tunnel-boring machine that will do the bulk of the work was purchased after it was used to dig a sewer line in San Francisco, Horton said.

Musk has said he wants to vastly improve the efficiency of the machine to prepare for a series of Hyperloop mass-transit tunnel networks nationwide. But Horton said Tuesday that this test tunnel is relying on existing technology.

“We hired a structural designer from a large consulting firm to design the tunnel based on LA Metro specs,” he said. “We haven’t reinvented tunneling. We’re using proven technology and proven means and methods.”
