WASHINGTON — Arlington fire officials are investigating a 20-inch water main break near South Dinwiddie Street and Columbia Pike.
Crews are in the area — south of route 50 and west of George Mason Drive — to fix the break. It is unclear how many people are without water service or how long it will take to restore.
More information as it comes.
