Innovator and businessman Elon Musk has a dream of making transportation a breeze by eliminating "soul-destroying" traffic.  In addition to his companies Tesla and SpaceX, he created the Boring Co. to build a series of tunnels beneath cities to make for speedy and easy underground transportation. 

Musk tweeted Wednesday the first segment of the tunnel under Los Angeles had been completed. He also noted the Godot boring machine used to create the tunnel still moved slower than a snail. Each of the boring machines will be named after poems or plays.

A video of the infrastructure he plans to build was uploaded in late April detailing what a trip using one of his tunnels would be like. It shows a red Tesla leaving a street full of traffic on a platform similar to an elevator. The platform takes the car underground to the tunnels where it then travels at 125 mph to its destination on a skate.

The company’s website and the video showing what travel in the tunnels might look like was posted two months ago, and work is already underway to make it a reality. They were put online just a day after a Boring Co. employee posted a photo of the company’s boring machine on Twitter.

“We’re trying to dig a hole under LA and this is to create the beginning of what will hopefully be a 3D network of tunnels to alleviate congestion,” Musk said during a TED talk in May, describing traffic congestion as "soul-destroying," especially in Los Angeles.

The elevator platform will accomplish the full integration of the entrances and exits to the tunnels into the cityscape. The plan is to bring the car underground and put it on a skate to travel. And currently, Musk sees no limit to the number of levels that could be added to the tunnels.

The biggest challenge Musk sees in creating the tunnel is one he runs into with most of his companies: cost. This is the same challenge holding back the first trip to Mars for SpaceX and a big challenge for making Teslas a vehicle for the average consumer.

The plan to make the 3D tunnel network more affordable is to take a couple steps to lower the cost. Those steps include cutting “the tunnel diameter by a factor of two or more,” and cutting the cross-sectional area by a factor of four, he said during the talk. His plan is to make it a diameter of only 12 feet, a little less than half of what a normal one lane tunnel is. The second step is to design a machine that tunnels and reinforces simultaneously instead of having one that splits its time between the two tasks.
