A tree has reportedly fallen, blocking the ramp from westbound Lee Highway to I-66, near Rosslyn.
Both lanes of the ramp are currently blocked. Drivers, including the driver of a commuter bus, could be seen heading back up the ramp in reverse. An Arlington County Police officer and VDOT sign truck are now on scene and blocking off the ramp.
Those on Lee Highway hoping to reach I-66 should continue heading westbound to the entrance near Spout Run.
No injuries have been reported as a result of the tree falling.
