Nashville Is a ‘Tough Place to Tunnel.’ Musk Is Digging Anyway.

Elon Musk, the world’s richest man, already faces backlash over his company’s giant supercomputer project in Memphis. Now, another project under his business empire has angered residents in Tennessee’s capital, where state officials cleared the way on Thursday for a 10-mile tunnel to be dug under Nashville.

The project by the Boring Company, Mr. Musk’s private tunneling venture, would connect downtown Nashville and the city’s airport. Gov. Bill Lee, a Republican, and other state leaders announced it this week, with little input from local lawmakers and residents, who raised objections to its fast-tracked approval.
