Arlington Ridge Road is closed between I-395 and 20th Street S. tonight due to a water main break.
Crews are currently digging up a portion of the road near the Hume School in an effort to repair the water main. The closure is expected to remain in effect through the evening rush hour.
Traffic is backed up on I-395 approaching the Ridge Road exit. Drivers attempting to head south on Arlington Ridge Road from Army Navy Drive are being directed onto I-395.
