the coordinates are the nearest transition point north of the city. Transition point being some point of intersection. It seems like this is a point where it appears 5 roads came together, if i remember correctly. I remember stopping to make sure we hit the right road. From your image posted earlier. i am not sure where the re-routed came from. It may be north of the point i am referencing. and north of workman mountain. I was trying to provide reference going north of that point. and keeping south of that point along the route in tact.
