Minnesota Department of Transportation is urging drivers to plan ahead and be cautious in work zones when heading out of town for Labor Day.

"Although major construction projects will be on hold for the weekend, motorists may still encounter lane restrictions and traffic delays," Transportation Commissioner Charlie Zelle said in a news release. "Your safety is important to us, so we ask that you plan your routes, stay alert and drive carefully in work zones."
