A Bridge and An Arms cache

My take on this is that making provision for a railway line is sensible and farsighted. It maybe that this new line may never be constructed – as with those to Namibia and Mozambique. But if, for whatever reason, a railway line to Zambia becomes a priority, an entirely new bridge would not need to be constructed, at probably crippling cost.  

However, the geography worries me. Many people, being aware that Rhodes’ bridge across the Falls links Zimbabwe and Zambia will wonder why a new link between thtis country and Zambia is necessary.
