WASHINGTON — Elon Musk tweeted his Boring Company’s latest tunnel project has received verbal approval from the federal government to build a hyperloop connecting New York City, Philadelphia, Baltimore, and Washington, DC.

According to The Verge, Tesla’s founder will continue to release new details about these projects. The hyperloop, a proposed ultra-fast method of travel first introduced by Musk in 2013, “would only take 29 minutes to travel between New York City and DC,” he claims. Musk also stated it would feature “up to a dozen or more” access points via elevator in each city.
