One of Johannesburg’s iconic landmarks, the Sentech broadcasting tower near Auckland Park, is literally falling apart. Bits of concrete are flaking off the 237 metre-tall structure. The tower is in a state of disrepair thanks in large part - it’s suspected - to acid rain that has rusted steel reinforcements in the tower. However, Sentech has assured residents in the area that the problems don’t pose a danger to them. There is no risk of the tower collapsing.The structure, which was erected in 1961 at a cost of just R300 000, will soon receive a major maintenance upgrade to fix the problems. Demolishing the structure is not an option: a new one would cost about R300m to erect.
