Erosion from the torrent of water unleashed by the break in the 36-inch distribution line washed away a portion of the trail that connects the southern section that’s accessible from the Roosevelt Island parking lot with the section north of Chain Bridge.
“The Potomac Heritage Trail is currently closed south of the Arlington County parking lot at the intersection of Glebe Road and Chain Bridge Road,” says an alert the National Park Service’s GW Parkway website. “The NPS is working with Arlington County and the PATC to identify a temporary re-route and a plan to reopen.”
NPS spokesman Aaron LaRocca confirmed to ARLnow that the closure was “due to trail damage as a result of the water main break on Glebe Road.”
So far there’s no word about when the trail might reopen.
