History
editConstruction of Lethabo started in 1980 and by December 1990, the station was fully operational. The station has been built on 11 000 concrete piles which were sunk 25 metres deep. The reason being to alleviate the heaving clay problem after some 190 000 bluegum trees were removed during site clearing. At the time, it was the largest piling contract ever awarded to a South African contractor.
