CT 41 is a north/south route passing through the northwest corner of Connecticut. It begins at the point where Dutchess CR 2 touches the state line and runs north through Sharon to Lakeville. It is multiplexed with US 44 for a little over a mile to the northeast from Lakeville to Salisbury. It then splits off to the north and continues to the border with Massachusetts, where it becomes MA 41.
