Westbound I-66 was temporarily blocked approaching the N. Glebe Road overpass due to a crash involving two vehicles this afternoon.
One of the vehicles ran off the side of the road into a ditch and overturned, according to scanner traffic. Another vehicle could be seen on traffic cameras stopped in the left-hand shoulder, but has since been moved to the right-hand shoulder.
Both lanes of WB I-66 were briefly blocked by debris and the emergency response, causing a lengthy backup that appeared to extend to the Rosslyn area.
So far, no serious injuries have been reported.
