I've done a little search on the net, looking for some other informations. These are the results:
a new map. The caption says:
A street circuit used for GT racing in the 1970s. The most memorable occurance is the collapse of the spectator bridge on the Start/Finish line during the 1972 event. The town was subsequentlt renamed Huambo.I looked for Huambo and Luanda in my atlas and they are two different cities, Luanda being the capital city of Angola, located on the coast, whilst Huambo is located about in the center of the country. Nevertheless in the sites I visited both the tracks, Luanda and Huambo, are also named "Nova Lisboa", probably the name of the capital, dating to the colonial era. What I wander is: are Luanda and Huambo different names of the same circuit, different circuit in the same city, or different circuit in different cities? boh?
this is the official site of the Angolan Motor Racing Club:
