If you've passed the Watergate or Rock Creek Trail and wondered what's behind the fences,

here’s the answer:

We’re building the Potomac River Tunnel, a 5.5-mile underground system that will:
✅ Go under DC, dug by massive tunnel boring machines
✅ Capture stormwater and sewage before it pollutes the Potomac
✅ Include diversion chambers, drop shafts, and overflow structures to protect our rivers year-round
It’s one of the largest clean water projects in DC’s history, and it’s happening right in our backyard.
