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.
At the dedication, Mayor Justin Wilson lamented the loss of former Mayor Kerry Donley, an AlexRenew Board Member, who died on Wednesday.
“Our hearts are certainly heavy this morning as we gather without Kerry,” Wilson said. “I think if there was ever a more fitting, audacious undertaking as a tribute to Kerry, it’s what we’re doing right here. Kerry always believed that this was a city that could do big things that were audacious, and their impact in their planning and scale. And this certainly is a mind-blowing exercise for this community.”
The tunnel boring machine was built in Schwanau, Germany, and was given the name Hazel, after environmental activist Hazel Johnson.
“Today we honor Hazel Johnson’s dedication to a cleaner, safer environment for future generations through the dedication of this tunnel boring machine, which will build a brighter future for all Alexandria,” said Karen Pallansch, CEO of AlexRenew Enterprises. “This 380-ton custom-built tunnel boring machine will soon begin to dig. How fast does she move? She moves about as fast as a snail creeping along a stick by Hunting Creek, and yet, and yet she’s gonna leave behind a lasting legacy.”
The Virginia General Assembly mandated in 2017 that the project be completed by July 1, 2025. The groundbreaking for the project was held last fall.
“It’s a good day for all of us,” said Delegate Elizabeth Bennett-Parker (D-45). “We were able to get $40 million additional dollars in this year’s state budget for this project, which will help us see it to completion.”
The tunnel project is partially funded through a $321 million loan from the Environmental Protection Agency’s Water Infrastructure Finance and Innovation Act and $50 million from the American Rescue Plan Act.
