A two-vehicle collision has destroyed the traffic control box at the intersection of Washington Blvd and N. Kirkwood Road, near Clarendon, cutting off power to the intersection’s traffic signal.

The t-bone crash happened at about 10:45 a.m. The driver of one car was transported to the hospital with minor injuries, a police officer at the scene said. A passenger in that vehicle and the driver of the other car involved were relatively unharmed.

As a result of the traffic signal outage, Arlington County police have set up cones in the intersection, diverting all southbound Kirkwood Road traffic to a right turn on Washington Blvd and preventing left turns in either direction on Washington Blvd.

Arlington County workers, after inspecting the damage to the power box, said it would take “all day, maybe until tomorrow” to repair. We’re told that they hope to restore at least some functionality in time for rush hour, perhaps finishing repairs on Tuesday.
