  About the highway: 
  According to the latest Bing satellite image, which is certainly several years old, the marking corresponds to the slightly more winding and busy track in the Mauritanian border town of Choum.
  In view of the expansion of other tracks in border areas, a continuously tarred highway can also be assumed here (2022).
