the bridge and approach slabs will be collected by a traffic bearing grated inlet. All areas in which fill slopes impact existing ditches will be replaced by a swale or inlet to maintain
existing drainage patterns. All pipe outlet locations will discharge to a rip rap dissipator pad at pipe outlets and sheet flow towards the river
