Who are the idiots doing the planning? If you are trying to solve the traffic mess on Highway 20 and Ferry Street, a roundabout will not help. The problem with traffic at that location is that there is not enough distance between that light and the traffic light at Highway 9 junction just to the west. Why not look at changing the light to where the Cook Road originally joined Highway 20 and eliminate the light at it's present location. That would give more distance between traffic lights and possibly eliminate some congestion.
A roundabout makes about as much sense as putting a Waste Disposal Site next to the High School. Another DUMB plan by our city officials who seem to have NO foresight and apparently DO NOT care what the citizens of Sedro-Woolley want.
