The R57 is a provincial route in South Africa that connects Vanderbijlpark with Phuthaditjhaba via Sasolburg, Heilbron and Reitz.

The R57 takes over the name Golden Highway from this junction southwards and makes up the border between the Muvhango Township & Vanderbijlpark Central.

After this intersection, the R57 becomes a highway (dual carriageway; passing under roads with off-ramps at certain junctions) and continues southwards for 4 kilometres, through the south-western suburbs of Vanderbijlpark, to cross the Vaal River into the Free State province.

[1] From the Vaal River crossing, it continues for another 3 kilometres, bypassing the Vaalpark suburb, to meet the R59 Sybrand van Niekerk Freeway at a major interchange north of Sasolburg Central.

It bypasses the town to the east and proceeds southwards for 24 kilometres to meet the R712 road (accessed by an off-ramp) next to the University of the Free State Qwaqwa Campus, marking its entrance into Phuthaditjhaba.
