Is a design exception required for a gore area? AASHTO shows shoulder widths requirements for gores?, so if those are not meant, is a DE required? If so, under which of the FHWA 13 controlling criteria does it fit in? Thanks!
 
I'm not sure what you mean. Could you explain more about what you think might need an exception?
