M2 Freeway, with Brixton Tower in the background, Johannesburg, Gauteng province

Johannesburg is heavily dependent upon freeways for transportation around the city due to its location 1500 metres above sea level, far from the coast or any major bodies of water.

There are 10 freeways in the Greater Johannesburg Metropolitan Area: the N1, N3, N12, N14, N17, R21, R24, R59, M1 and M2. The M2 runs the length of the central part of the city east-west, from Germiston to Main Reef Road.

Sentech Tower, a 237 metres high TV tower in the Brixton suburb of Johannesburg, South Africa, is a well-known and easily identifiable landmark in the city, shown here in the background at left. Originally called the Brixton or Albert Hertzog Tower, it is 237 metres high.
