The designated highway ran along Mission Road's entire length for several years until being decommissioned by 1980 by the New Jersey Department of Transportation (NJDOT).
Mission Road, the former alignment of Route 160 begins at an intersection with US 206 in the Parsonville community of Bordentown Township.
Passing far to the east of Northern Community Park, the highway intersects with several dead-end residential streets.
Paralleling US 206 to the east, Mission Road continues northward, forking to the left at an intersection with Liberty Avenue.
On that day, Route 39 was decommissioned in its entirety, leaving the divided highway only US 206, and the alignment of Mission Road received the designation of 160.
