Hi !
• This message is translated in English, but if you're French, feel free to ask in French ! :)
• You can ask clarifications to the contributor via https://www.openstreetmap.org/changeset/111352776
• The concerned way is https://www.openstreetmap.org/way/984471515
• According to satellite imagery, which is from months and years ago, the road doesn't seems to exist.
• The road isn't visible on some layers because OSM datas aren't refreshed immediately, depending of the layer/tile provider, it could take hours/days/weeks/or months (rare !)
• The road isn't visible on every scale, possibly due to OSM servers overload. It now seems fixed. If not, you may need to refresh you cache – press CTRL + SHIT + R.

Hope it helps !
