would connect up with an east/west motorway running just south of the Johannesburg CBD. A third section involved the reconfiguration of roads to form an eastern CBD bypass connecting the north/south motorway with Saratoga Avenue. 1958 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. Where Harrow Street met Louis Botha Avenue in Berea, this was to become an underpass of the latter. At the southern end of Harrow Road, a flyover would cross Saratoga Avenue and would eventually connect with the redesigned Siemert and Sivewright Roads. 1959 Planning began for six-lane bridge that would have to cross the Braamfontein Railway Yard and would be part of the M1 motorway to connect the city with its northern and southern suburbs. 1962 Construction finally began in 1962 on the Braamfontein Railway Bridge in Braamfontein required to connect the future M1 north and southern motorways. The Johannesburg City Engineer Department began its planning for the M1 motorway, that included a motorway from the Braamfontein Railway Bridge under construction, south to a future Westgate Interchange and included a double-decker section above Goch Street. The construction on the Sivewright Road / Berea Street and the Siemert Road / End Street reconfiguration, important to connecting the future eastern bypass connecting the M1 in the northern suburbs at the proposed Killarney interchange with the M2 East at the proposed Heidelberg Interchange, was nearing completion. Both road reconfigurations were situated in Doornfontein, east of the Johannesburg CBD. 1963 The Johannesburg City Engineer Department continued its engineering work on plans for Goch Street double-decker section of the future M1 North route. Planning also started on a future M1 South bridge and interchange at Xavier Street in Robertsham. 1964 Johannesburg City Engineer Department’s planning was completed on the Goch Street double-decker section on the future M1 northern route. The design called for a 1,100 m section made up of a 500m double-decker motorway and two 300m sections on either end of the main section. Planning begun on the M1 motorway, heading northwards, in Braamfontein to construct a cutting through what then was known as the University Ridge. This route would separate the Witwatersrand Agricultural Society grounds and the University of Witwatersrand. Also planned was a forty-metre bridge allowing Showground Road (now Enoch Sontonga Avenue) to cross the new motorway
