Hurricane force winds cause 18-wheeler to flip on Alligator River Bridge in Outer Banks, North Carolina

The Alligator River Bridge, which connects Tyrrell and Dare counties, closed around 10:15 a.m. when the big rig turned over. The National Weather Service says winds at the bridge were clocked at 77 miles per hour, which is just above hurricane force. The cab of the 18-wheeler is on the bridge, while part of the trailer is hanging over the side.
