Hi there waldyrious! In my mind the basis data is not the best in Portugal, as you may have noticed;) If you are still serious about this note, I could add dozens like this just in Braga. Let alone Viana. Here I would like to help blind people over the road, so I'd ignore the fact, that there's obviously a duplication. And I'm not able to tinker with OSM generic data btw, but I'm open for a discussion on what to do :) best regards
