So you have a crowd of people holding a rope to get a single person over one at a time. Obviously there's some demand for that bridge. Why go a half mile out of the way when there's a bridge *right there*? Even niggers were able to figure that out, well it does kind of fit their laziness tendency...
Ethiopia didn't rebuild it because they moved their capitol 80 years prior, making the bridge obsolete.

There is a bridge half a mile down the road.
