On Thursday, Maryland officials gave Elon Musk’s Boring Company permission to dig a 10.1-mile tunnel “beneath the state-owned portion of the Baltimore-Washington Parkway, between the Baltimore city line and Maryland 175 in Hanover,” according to the Baltimore Sun.
According to Maryland Transportation Secretary Pete Rahn, The Boring Company (which Tesla and SpaceX CEO Musk founded to advance tunneling technology) wants to build two 35-mile tunnels between Baltimore and Washington, DC. The federal government owns about two-thirds of the land that Musk’s company would need to dig underneath. As of Friday, it was unclear whether that permission had been granted. (A Department of Transportation spokeswoman told Ars that the land in question was owned by the National Park Service, which did not immediately respond to request for comment.)
But the 10 miles that have been approved by the state of Maryland will for the first leg of an underground system that could contain a Hyperloop system. Musk first floated the idea of a Hyperloop—which would ferry passengers through a low-pressure tube in levitating pods floating above a track using air-bearings—in 2013. But the CEO determined that he didn’t have time to see his idea through to fruition, so he issued a white paper and challenged startups and students alike to make headway on the concept.
