The N3 is a national route in South Africa that connects Johannesburg and Durban, respectively South Africa's largest and third-largest cities. Johannesburg is the financial and commercial heartland of South Africa, while Durban is South Africa's key port and one of the busiest ports in the Southern Hemisphere and is also a holiday destination. Durban is the port through which Johannesburg imports and exports most of its goods. As a result, the N3 is a very busy highway and has a high volume of traffic.
Johannesburg is heavily dependent upon freeways for transport around the city due to its location 1,500 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. In addition, three new freeways are planned: the G5, G9 and G14. Freeways are sometimes called highways or motorways colloquially.

The N3 Eastern Bypass is a section of the Johannesburg Ring Road that forms a beltway around the city of Johannesburg, South Africa, as part of the N3. The first section of the freeway opened in 1971, from Buccleuch to the interchange with Main Reef Road in Germiston. This is one reason why Germiston is listed as the southbound destination of this route, from the Buccleuch to Geldenhuys Interchanges, rather than to the Elands Interchange south of Germiston. The remaining section from Main Reed Road to Black Reef Road, which included the construction of the Geldenhuys Interchange, was opened in 1977, linking the Eastern Bypass with the N3 freeway to Heidelberg. The interchange at Main Reef Road was removed.

Known at the time as the Concrete Highway, the freeway was initially opened in 1975 as a route to avoid the city centre of Johannesburg and to provide access to the western areas of the Witwatersrand. From the south, the Western Bypass begins at the Diepkloof Interchange in Soweto, where it splits from the N12 freeway and ends at the Buccleuch Interchange, where it merges with the N3 Eastern Bypass, M1 South and N1 Ben Schoeman freeways.
The N12 Southern Bypass is a section of the Johannesburg Ring Road that forms a beltway around the city of Johannesburg, South Africa, as part of the N12. The freeway was the last section of the Ring Road to be built, with the final section opening in 1986. As part of the old South African Freeways, It was initially called the N13. The entire Southern Bypass freeway was an e-toll highway from 3 December 2013 to 11 April 2024.
