The Boring Company unveiled further details about its proposed “loop” route between Baltimore and Washington, D.C., on Thursday, a high-speed underground transit project that is designed to meet the requirements for hyperloop. Elon Musk’s venture — which has used a curious funding model of flamethrowers and hats — plans to fully fund the 35-mile tunnel that will initially move pods at speeds of between 125 and 150 mph.
The proposal is the latest under the company that wants to revolutionize the exciting world of tunnel boring. The parallel, twin underground tunnels will sit at least 30 feet deep. The project is expected to take between 12 and 20 months depending on machine speed, with the construction of four machine “launch pits” taking around four weeks. The only other surface penetrations will come from ventilation shafts and emergency exits (around 20 but no more than 70, between 12 and 24 feet diameter) and stations “the size of a few parking spaces” and “widely distributed in a network,” built on private land with local government input on location. Autonomous electric skates will transport either a single passenger vehicle or a pod of between eight to 16 passengers, with pedestrians and cyclists prioritized over cars.
