 This latest construction project comes after a new study from the North Dakota Department of Transportation that says roundabouts have helped save lives in the state. We first told you about that study last week on WDAY News. In North Dakota, overall crash numbers have been cut by a third, and crashes resulting in severe injury or death are down 59%. State officials say roundabouts are part of the reason for that. John has the 10-day forecast now, and mild weather will return next week, John.
