The Western Bypass is a section of the N1 and the Johannesburg Ring Road located in the city of Johannesburg, South Africa.
 The freeway was initially opened in 1975 as a route to avoid the city centre of Johannesburg and access for 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.
 The Western Bypass ends at the Buccleuch Interchange, where it merges with the N3 and M1 freeways.
 The interchanges with which it coincides are (from south to north): Rand Show Road, Soweto Highway, ("soon to be an interchange with the N17 highway"), Maraisburg Road, Gordon Road, 14th Avenue, Beyers Naudé Drive, Malibongwe Drive, William Nicol Drive, and Rivonia Road.
The Technikon Witwatersrand was a technikon located in Johannesburg, South Africa.
 On 1 January 2005, it merged with Rand Afrikaans University and the Soweto and East Rand campuses of Vista University to form the University of Johannesburg.
 The former Vista University East Rand Campus has subsequently been permanently closed.
The Rand Show, also called the Rand Easter Show is an annual show held in Johannesburg, South Africa, and is the largest consumer exhibition in Southern Africa.

Troyeville is a suburb of Johannesburg, South Africa.
 It is a small suburb found on the eastern edge of the Johannesburg central business district (CBD), with the suburbs of New Doornfontein, Bertrams and Lorentzville to the north, Fairview to the south and Kensington to its east.
 The main road through the suburb is "Albertina Sisulu", has its eastern end in the suburb and connects the CBD to Johannesburg's eastern suburbs and towns of the East Rand.
 It is located in Region F.
The mansions of Parktown (a suburb of Johannesburg, South Africa) are an important part of the history of the city of Johannesburg.
 They were the homes of the Randlords, accountants, military personnel and other influential residents of early Johannesburg, dating back as early as the 1890s.
 The first of these mansions, "Hohenheim" was designed by Frank Emley and was built for Sir Lionel Philips and his wife Lady Florence Phillips.
 The name Hohenheim had been used originally by Hermann Eckstein, one of the first Rand Lords to name his house after the place of his own birth.
 When Philips became the head of Eckstein & Co, he moved in to Eckstein's house but due to the expansion of the city decided to build the new Hohenheim in an enviable site further from the mine workings.
 Sir Lionel Philips was banished from the Republic for his involvement in the Jameson Raid.
 It is perhaps fitting that the next occupant of this famous house was none other than Sir Percy Fitzpatrick, the author of the best selling book 'Jock of the Bushveldt'.
 The house was demolished but a plaque remains in honor of this important building.
