“A Class 6 road section of Cobble Hill Rd not open to motor vehicles.”
— Eric LaRoche
This is the "Class 6" section of Cobble Hill Road. The classification means the road has been discontinued or is no longer maintained so it can be traveled at the users' own risk. It's not on a lot of maps, but it is there and can be used as a bail-out or as an access route. Additionally, it can be used as a pretty easy loop by adding in a piece of Old Chesterfield Road
and Cobble Hill Road.
