South George Mason Drive was been shut down from Route 50 to Columbia Pike today due to an accident involving a construction vehicle.
It happened near the National Guard Readiness Center, where a considerable amount of construction is taking place.
The raised boom of an excavator struck overhead power lines while it was traveling north on George Mason Drive, police said. The impact caused an adjacent transformer power pole to splinter and collapse, and caused live power and communications lines to fall onto the street.
As of 2:30 this afternoon, the road has partially reopened. It is expected to fully reopen in time for the evening rush hour. It will then close again around 7:00 so Dominion Power crews can make further repairs.
