The route is not very long. It starts at Fortuna Heights, and climbs it's way up a hill, past Overlook, and connects up to Highway 142 there. If you stay left, you will go over a bridge crossing the highway, and then the road will merge with the highway going north. If you turn right, the road will almost instantly merge into the highway, which is going south.
