Put your brain into thinking mode and ask yourself how you would both design and actually make a network of practical and lasting roads all across the African continent without disrupting needlessly the present ecosystem and livelihood of the peoples? Additionally make sure this system uses ONLY locally sourced and manufactured raw materials preferably those that are readily available. Remember be “ORIGINAL” in your thinking do not simply regurgitate what you read in text-books as the solution as these roads need to be maintained locally and not dependent on western tools or man-power etc.
