The Hyperloop project aims to transport people in vacuum tubes that propel vehicles at very high speeds. A boring machine named Lady Bird completed its 2-year, 4.5-mile tunneling mission for DC Water’s Clean Rivers Project. Mark Segraves reports. Musk toured a DC Water tunnel, but the water utility is not working with him, Lisle said. Groups regularly tour their project sites. DC Water completed the Anacostia River Tunnel in November. The tunnel 23 feet in diameter diverts sewage from the river. It runs from Southeast D.C. near RFK Stadium to the other side of the river, near the Anacostia Metro station.
