Virginia State police told us the driver came up on a rolling road block, as road crews worked on the bridge by exit 17.
"He wasn't paying attention, and it was either hit the truck that was in the running road block or hit the ditch. He close to hit the ditch, and it overturned. He lost control," said Ron Hughes, Master Trooper with Virginia State Police.
No injuries were reported, but traffic was backed up for a few miles as a wrecker worked to clear the scene.
