All the world's roads, mapped

 I love a map, and I particularly love a map of things that are interesting. This is a map of roads in the world. You can select it to get a much bigger and more complete picture. Africa is interesting here since the north around the Mediterranean is not connect to south of the Sahara.

The dense spots in Africa are South Africa, Zimbabwe, and Zambia in the south and Ethiopia in the east of the continent.
