The only sensible thing to do about Stickle Road is to close it off from the highway completely.
Anyone along Stickle Road can access the highway by travelling north, along Pleasant Valley Road to Swan Lake, and anyone heading south will just have to head into Vernon, along Pleasant Valley Road, to get out on to the highway.
What is so difficult about that?
The people in the RV park across the highway from Stickle Road will just have to live dangerously until a middle lane between the highway lanes on the highway is constructed, so the RVs can cross the highway more easily.
There is no need for a light at Stickle Road.
