For most of its length, this road is tagged with name=Обход на Смолян as well as noname=yes These cannot be both correct ;) Does the road have an official name, and if so, what is it? FYI on https://kais.cadastre.bg/bg/Map the western end is named Коста Аврамиков and somewhere halfway it is named Околовръстен път... Cadastre data are full of mistakes, though.
