Dane County will be starting on Monday, August 4, 2025, their County Highway N improvement project from the City of Sun Prairie limits (Progress Way) to the north Dane County line.  The highway will be closed to through traffic during this project, but all homes, businesses and emergency services will have access.  Most of the culverts will be done with a daily closure from 7:00 am to 4:00 pm., but some will require an overnight closure.  For everyone's safety, travelers are encouraged to slow down and be alert when in the construction zone.  If possible, avoid the area during the active construction hours.
