We just reached a MAJOR milestone on the Potomac River Tunnel Project 💧 Today, crews successfully lowered the front shield of Tunnel Boring Machine Mary into the underground shaft 60 feet below ground. This is a key step toward building the 5.5-mile tunnel that will help reduce sewer overflows into the Potomac River. With today’s lift complete, tomorrow the cutterhead will be lowered and assembled underground, and the middle shield will follow on Friday as assembly continues. A big step forward

This is what progress on the Potomac River Tunnel looks like from 30,000 ft. 👀 DC’s next big infrastructure milestone? It's happening right under one of our most iconic parks – West Potomac Park, next to the National Mall. Those holes you see in the ground will soon house our tunnel boring machines, which will dig deep to create our Potomac River Tunnel. West Potomac Park is home to more than trees and trails…It’s home to change. 🙌 #PotomacRiverTunnel #DCWater | DC Water

Some more exciting news on your timeline today, coming to a cleaner river near you 😉💧 Today, crews lowered the 21-foot cutterhead for Tunnel Boring Machine Mary into the Potomac River Tunnel shaft. It’s the part that cuts through the rock and soil to build the tunnel and a key piece as Mary is assembly underground. Once complete, the tunnel will capture sewage overflows in heavy rain so less ends up in the river. Piece by piece, we’re getting closer. #DCWater 🙌 | DC Water
