TheM2 is a majorhighway andmetropolitan route inGreater Johannesburg,South Africa. It is named theFrancois Oberholzer Freeway. It runs just to the south of theJohannesburg Central Business District eastwards where it connects with theN3 (only a short segment goes to the west of the Johannesburg CBD) and entersGermiston, ending near its CBD. The north–southM1 intersects with the M2 just to the south-west of the Johannesburg CBD.
The M2 route begins just west of theGermiston city centre (capital ofEkurhuleni).[1]: 111 It begins by heading westwards from Jack Street at the junction with theM93 Refinery Road, immediately becoming a freeway (Francois Oberholzer Freeway).[1]: 111 The motorway continues westwards and reaches the Geldenhuys Interchange with theN3/N12 highway (Johannesburg Eastern Bypass), where it exits Germiston and crosses intoJohannesburg.[1]: 110 Crossing under the N3 highway, it continues westwards as the road separating the two industrial areas ofHeriotdale andCleveland and reaches its first off-ramp with theM33 Cleveland Road.[1]: 110 It continues westward to the Denver Interchange at Chilvers Street.[1]: 109 Shortly after that interchange, there is an exit and on-ramp from the M2 West at theM19 Ruven Road and the same for the M2 East intersection at New Goch Road.[1]: 109 The motorway continues westward past the Kaserne Railyards to the Maritzburg Street Interchange.[1]: 108 A short distance past that interchange, it passes through the Heidelberg Road Interchange.[1]: 108 This interchange connects with theM31 North Joe Slovo Drive (which is an eastern bypass of the CBD to the northern suburbs and theM1 North) and the M31 South Heidelberg Road toAlberton.[1]: 108 It then passes shortly over theM11 Mooi Street allowing traffic to exit the M2 East and enter the M2 West.[1]: 108
Passing over Rosettenville Road, it reaches Eloff Street where off-ramps on M2 West allow exits to Stott Street and theM9 Rissik Street while the M2 East allows an exit to the M9 Rissik Street and an on-ramp from Village Road.[1]: 108 Continuing westward it crosses over theM27 Simmonds Street with an on-ramp to the M2 East and then the route crosses Booysens Road and reaches the Westgate Interchange.[1]: 107 Here vehicles can enter and exit the M2 from Ntemi Piliso Street, leave the M2 and exit north on theM1 crossing the CBD via the Goch Street double-decker overpass or exit south to M1 and the southern suburbs.[1]: 107 The M2 continues westward to the Crown Interchange that allows vehicles from M1 South to head east or west along the M2.[1]: 107 Passing through the Crown Interchange, it flies over Treu Road into the suburb ofCrown and ends shortly thereafter at a junction with theR41 Main Reef Road, which heads toRoodepoort in the west and theJohannesburg CBD in the north-east.[1]: 107
Both the M2 and M1 motorways have their beginnings in a 1948 traffic planning scheme developed by theJohannesburg City Council and examined by American traffic engineering consultantLloyd B. Reid in 1954.[2]: 577 Two 10-year plans examined among other things the idea of new urban motorways and improving existing highways. The plan called for two motorways, one running east–west along the southern CBD and the other running north–south on the western side of the CBD.[2]: 577 The plan was linked to the national and provincial governments plan by the National Transport Commission for theWestern andEastern Bypasses, the future N1 and N3/N12.[2]: 577 The East-West Motorway (M2) would have its beginning at the Eastern Bypass now known as theGeldenhuis Interchange, though it presently begins further eastwards inGermiston at Refinery Road.[2]: 577
The motorway would then continue westwards over old mining properties and original gold-bearing reefs ending at Main Reef Road near Church Street.[2]: 577 The plan was for it to eventually reach the proposed Western Bypass, but it never did.[2]: 577 Apart from several diamond interchanges connecting to existing main roads in and out of the city, there would be two largeinterchanges that would be built onmine dumps.[2]: 578 The first would be constructed near New Kazerine and would connect Heidelberg Road to the south and Harrow Road (now Joe Slovo Drive) northwards while the second large interchange, further on, would connect the North-South Motorway (M1) and the laterCrown Interchange.[2]: 578 Provisions would be made for the vertical and horizontal movement of land due subsidence of undermined land especially where old mine stopes had not been properly filled.[2]: 578
A two-three-lane motorway was planned with large medians for breakdowns, elevated where required, and the speed limit set at between 80 and 100 km/h (50 and 60 mph).[2]: 577–8 The motorway is named after City of Johannesburg councilor J. F. Oberholzer, who was the head of the council's Works and Traffic committee.[2]: 405
An early long-term motorway plan was envisaged for a future Johannesburg. The first was a north–south motorway of 18.4 km stretching from Westgate just south of the Johannesburg CBD to connect up with the existing main Pretoria Road, 5.6 km outside the Johannesburg municipal boundary in the north suburbs.[3]: 328 The Westgate section would connect up with an east/west motorway running just south of the Johannesburg CBD.[3]: 328 A third section involved the reconfiguration of roads to form an eastern CBD bypass connecting the north–south motorway with Saratoga Avenue.[3]: 328
Improvements began on Harrow Road (Joe Slovo Drive) to widen and deepen the road and included new bridges crossing over it at Joel Road, Alexandra Street and Barnato Street's.[3]: 328 Where Harrow Street (Joe Slovo Drive) metLouis Botha Avenue inBerea, this was to become an underpass of the latter.[3]: 328 At the southern end of Harrow Road (Joe Slovo Drive), a flyover would cross Saratoga Avenue and would eventually connect in the future with a redesigned Siemert and Sivewright Roads.[3]: 328
The construction on the Sivewright Road / Berea Street and the Siemert Road / End Street reconfiguration, important to connecting the future eastern bypass with the M1 in northern suburbs, at the proposedKillarney interchange, with the M2 East at the proposed Heidelberg Interchange, was nearing completion.[3]: 329 Both road reconfiguration's were situated in Doornfontein, east of the Johannesburg CBD.
An investigation began on the planned route of the east/west freeway to examinesoil quality of the mine dumps andslime dams as well the position and depth of mine tunnels.[3]: 329 Contracts were issued for the section of the M2 freeway from the Westgate Interchange eastward to Mooi Street.[3]: 329 Contracts were also issued for the planning of the Heidelberg Interchange and its connection to Harrow Road (Joe Slovo Drive) bypass.[3]: 329
The Harrow Road (Joe Slovo Drive) scheme was completed.[3]: 329 Improvements on Harrow Road (Joe Slovo Drive) widened and deepened the road and included new bridges crossing over it at Joel Road, Alexandra Street and Barnato Street's.[3]: 328 Where Harrow Street (Joe Slovo Drive) metLouis Botha Avenue inBerea, this had become an underpass of the latter.[3]: 328 Work continued on the Berea-Sivewright motorway bypass works.[3]: 329
Work that had started on the eastern-bypass, the Berea-Sivewright Street section, was completed. At the southern end of the M1 Goch Street double-decker section, work began on the Westgate Interchange that would connect the M1 and M2 motorways but work was problematic when mine workings below the site became an issue.[3]: 331
The Heidelberg Interchange was put out to tender and would cost R3.9 million.[3]: 331 The rest of the M2 motorway was under tender or construction was beginning on the motorway.[3]: 331
Work on the Siemert Road / End Street route making up part of the eastern bypass was completed.[3]: 331
By this year, the Heidelberg Interchange was nearing completion.[3]: 332
Construction of the Crown Interchange that would connect the M1 North–south route with the M2 was postponed when the tenders received were consider too expensive.[3]: 332
The Crown Interchange tender on the M1/M2 was finally awarded and a completion date set for 1974.[3]: 332 Heidelberg Interchange on the M2 eastern section was opened and connected the eastern CBD bypass to the M1 in the northern suburbs.[3]: 332 A section of the M2 freeway between the Maritzberg Interchange and Heriotdale off-ramps had been completed and was opened to traffic between those two sections.[3]: 332 Work on the section called the Kazerne Viaduct east of the Heidelberg Interchange was still under way.[3]: 332
Part of the route connecting the Crown Interchange to the Westgate Interchange was now open to traffic.[3]: 332 Work on the section called the Kazerne Viaduct east of the Heidelberg Interchange was still not completed.
The M2 was now fully open with the completion of the Kazerne Viaduct east of the Heidelberg Interchange. Work connecting the M2 to the N3 Eastern Bypass on the eastern border with Germiston was not completed as the Geldenhuys Interchange was still being built by the Transvaal Roads Department.[3]: 333
This year saw the completion and opening of the Geldenhuys Interchange which saw the M2 connected to the N3 Eastern bypass.[3]: 334
The final cost of the twelve-year M1 and M2 project was R85.5 million through the awarding of twenty-seven contracts. The Provincial and National government's contributed R21 million of the final cost while land acquisitions represented 19% of the final cost. The project moved 8.3 millioncubic metres of land made up of 0.3 million cubic metres of rock, 8 million cubic metres of slime and earth. Eighty new bridges were constructed and ten mine dumps moved. Seventy kilometres of drainage pipes were laid and 500,000 cubic metres of concreted poured.
