Water Main Break in Arlington County, Virginia: Road Closure to Lift by Sunday Morning
A water main break occurred on Saturday, August 9, 2025, at the intersection of Columbia Pike and S. Dinwiddie Street in Arlington County, Virginia. The break caused a significant disruption, with S. Dinwiddie Street being closed from 8th Road to Columbia Pike in both directions.
Crews have been working tirelessly on the repairs, focusing on a 20-inch feeder main. The estimated completion time for the repairs was early Sunday morning around 2 a.m., and service was restored roughly an hour after isolating the break at about 2:15 p.m. Saturday.
Due to the repairs, pedestrian traffic was also closed off. However, with the repairs nearing completion, the road closure on S. Dinwiddie Street is expected to be lifted by 10 a.m. on Sunday morning.
Officials have advised drivers to expect delays and seek an alternate route. The exact alternate routes were not detailed in the sources provided, but it is advisable to avoid the Columbia Pike and S. Dinwiddie Street area due to the closure and follow posted detours.
Unfortunately, the water main break led to a significant environmental impact, including a mass fish kill downstream in Four Mile Run due to discharged chlorinated water.
