in Centurion, the Ben Schoeman Highway becomes the N1 to Johannesburg, and the N14 continues as the intersecting west-south-western highway towards Krugersdorp. The R114 parallels the N14 from Centurion to Muldersdrift. The R21 provides a second north–south highway, further east. It starts from the Fountains Interchange south of the city centre, heading south-east to Monument Park, when it becomes a highway and a toll road. It crosses the N1 at the Flying Saucer Interchange and runs north–south towards Ekurhuleni (specifically Kempton Park and Boksburg). Importantly, it links Pretoria with the OR Tambo International Airport in Kempton Park. The R80 highway is a highway in the north-west of the city. The highway begins in Soshanguve and it terminates just north of the city centre at an intersection with the M1. Pretoria is also served by many regional roads. The R55 starts at an interchange with the R80, and runs north–south from Pretoria West to Sandton. The R50 starts from the N1 in the south-east of the city, and continues south-east towards Bapsfontein and Delmas. The R511 runs north–south from Randburg towards Brits and barely by-passes Pretoria to the west. The R514 starts from the M1, north of the city centre, and terminates at the R511 in Hartbeespoort. The R513 crosses Pretoria's northern suburbs from east to west. It links Pretoria to Cullinan and Bronkhorstspruit in the east and Hartbeespoort in the west. The R566 takes origin in Pretoria's northern suburbs, connecting Pretoria to Brits. Finally the R573 starts from the R513, just east of the town and heads north-east to KwaMhlanga and Siyabuswa. Pretoria is also served internally by metropolitan routes.
