Tunnel boring machine Lucy Diggs Slowe finished work on the First Street Tunnel in Bloomingdale, as part of the First Street Tunnel Project.
The First Street Tunnel is 2,700 feet long and 23 feet in diameter, built under First Street NW from Rhode Island and First Street, to the southwest corner of the McMillan Street. The machine has been creating about 50 feet of tunnel per day. Named after a local activist who was the first Dean of Women at Howard University, Lucy Diggs Slowe began digging in July.
"As long as she's been mining, December has been our target" deadline, says John Lisle, D.C. Water's chief of external affairs.
