A water main break has shut down roads in the Arlington area Thursday morning, Arlington Water said.

The eight inch water main break has shut down the area of S Glebe between 18th and 20th Streets South.

Crews have responded and are working on repairs. It will take between six to eight hours for crews to fix it, Arlington Water said. The water has been turned off.

There is no estimate on how many people are impacted. The water main break was first reported around 3:15 a.m.
