I remember reading (a very long time ago) that one of the primary use cases for using airships for carrying cargo was in regions that don't have an existing highway system to support fleets of big trucks. Africa in particular doesn't have superhighways crisscrossing the continent. A quick search suggests that one Airlander costs about as much as 10 miles of two lane highway.
