Some folks are concerned about impacts to scenic beauty due to changes to road template. I think – they project another major re-sculpting of landscape like what happened on 385 re-construction. Other possible concerns – improper culvert designs interfering with fish travel within surface waters, run off from road effecting water quality in streams, especially Spearfish Creek, that supports American dipper..
