The Door County Highway Department says County T will be closed to traffic east of Ridge Road, in the Town of Sturgeon Bay, Monday. Patrol Superintendent Thad Ash says the closure is needed because of the replacement of a large culvert. He says the hope is to have the road open to traffic by the end of the day on Tuesday or as soon as it is safe to travel. The department apologizes for any inconvenience the closure on County T may cause.
