⚙️ Meet “MudHoney”, the TBM that dug beneath Seattle!
With a diameter of approximately 6 meters, it completed the excavation of the Ship Canal Water Quality Project in Washington State: a large underground storage tunnel built by The Lane Construction Corporation (Webuild Group) for Seattle Public Utilities.
🌊 Designed to reduce the discharge of untreated stormwater and sewage into the Lake Washington Ship Canal, Salmon Bay and Lake Union, the tunnel will help protect Seattle’s waterways by preventing up to 75 million of gallons of contaminated water from overflowing into them every year.
