Elon Musk first shared his vision for the company in December 2016, promising to solve traffic woes with networks of tunnels for city centers. It is now adding the finishing touches to its first burrow, a test track running beneath the city of Los Angeles.

By shrinking the size of tunnels, automating the machines that dig them while also powering them up, The Boring Company is hoping to cut the costs of tunneling by a factor of more than 10. It also plans to turn the excavated rock into Lego-style bricks for low-cost housing.

It has also proposed a network of tunnels for LA that would connect locations like Long Beach Airport, the downtown area, LAX, UCLA and Dodger Stadium. But first it's all about baby steps, with the company getting to work on its first test tunnel that begins at its headquarters in LA.
