The Virginia Department of Transportation is closely monitoring wind speeds on bridges in the Northern Neck and Middle Peninsula regions from today into early next week. High-profile vehicles should not cross bridges when a High Wind Advisory is posted. An Advisory will be posted when sustained winds reach 30 mph over a period of 30 minutes, or there are frequent wind gusts of 45 mph or greater. When sustained winds reach 45 mph or above over a period of 15 minutes a bridge closure notice will be posted.
