It moves at a snail’s pace, but Alexandria’s tunnel boring machine is ready to drill through 100-foot-deep soil to prevent millions of gallons of combined sewage from flowing into the Potomac River, Hooffs Run, and Hunting Creek.
On Thursday, Alexandria’s leaders were on-hand for the unveiling and dedication of AlexRenew’s RiverRenew Tunnel Project. The $454.4 million project is the largest infrastructure project in the city’s history, and will result in a 12-foot-wide, two-mile-long waterfront tunnel, which will divert approximately 120 million gallons of sewage every year.
