Washington, DC: “Lady Bird,” the Tunnel-Boring Machine

Posted by Infra on Tuesday, April 22nd, 2014

To reduce DC waste by 98 percent, the 20-year D.C. Clean River Project has a 1323-ton, 442-foot tubular machine digging a 23-foot-diameter concrete water tunnel.

DC Water named its massive tunnel boring machine Lady Bird, christened it with DC tap water, and prepared to send it underground to tunnel more than four miles.
