On Sunday night, Tesla, SpaceX, and Wearisome Company CEO Elon Musk tweeted "The first tunnel is scrutinizingly done," subtracting that the tunnel will unshut December 10. "The first tunnel" refers to the initial tunnel that The Wearisome Company has been digging under the streets of Hawthorne.

Work began on that project virtually the start of 2017, when Musk moved excavation equipment into what was then SpaceX's tiny employee parking lot and began digging. Since then, Musk has purchased a wearisome machine to tunnel under the Los Angeles neighborhood with the hope of making modifications to the machinery that will indulge tunnels to be dug increasingly quickly.

According to The Wearisome Company website, the Hawthorne tunnel "leaves SpaceX property (parking lot east of Crenshaw Boulevard and south of 120th Street), turns west under 120th Street, and remains under 120th Street for up to 2-miles." Musk tweeted last night that pods in the tunnel will unzip a top speed of 155mph (250km/h). The CEO widow that there will be an opening event on the evening of December 10 and self-ruling rides for the public on the pursuit day.
