County crews are working to repair a “large water main break” in Pentagon City.
The break happened this morning near the intersection of S. Hayes Street and 15th Street S., resulting in a partial road closure and some 100 units in a high-rise building to lose water pressure.
Repairs to the 12-inch water main are underway and expected to take until midnight tonight, according to the Arlington Dept. of Environmental Services.
“The street is partially closed, with traffic being diverted,” DES said.
Photos from around 11 a.m. show water bubbling up from the sidewalk and pooling in the roadway, a block from the mall and from Costco.
UPDATE #2: Some 100 customers in a high-rise building could be experiencing impacts to water service. The street is partially closed, with traffic being diverted. Updated estimated repair completion: 12 AM Friday. Questions? Call 703-228-5000 or 703-228-6555 after 7PM.
