DC Water Launches Tunnel Boring Machine Mary, Marking Important Step for Potomac River Tunnel Project
First turn of cutterhead signals the start of excavation for the Potomac River Tunnel Project
In a defining moment for one of the District’s largest infrastructure investments, DC Water has marked its next major milestone in the Potomac River Tunnel Project. The first tunnel boring machine, Mary, has launched her northbound journey breaking through the soil to signal the start of excavation.
With the first turn of Mary’s drill-like cutterhead underground, the machine pushed forward to begin tunneling, representing the transition from years of planning and preparation to active tunnel construction on the $819 million project.
