The M31 road is a metropolitan route in the City of Tshwane in Gauteng, South Africa. It connects the southern suburbs of Centurion, from the Rietvlei Nature Reserve to Rooihuiskraal via Irene and Highveld.

Route

The M31 route begins just south-west of the Moreleta Park suburb in southern Pretoria, at a junction with the R50 route (Delmas Road). It begins by heading south-west for 4.5 kilometres, forming the northern border of the Rietvlei Nature Reserve and bypassing the Rietvlei Dam, to reach a junction with the M57 (Goedehoop Avenue). It proceeds westwards as Nellmapius Drive to cross the R21 highway and enter the southern suburbs of Centurion. It enters the Irene Village and reaches the Irene Village Mall just after the R21 interchange, where it meets the southern terminus of the M28 (Van Ryneveld Avenue).

The M31 proceeds westwards to reach a junction with the M18 (Main Road) in Irene before crossing the Hennops River south of the Centurion Country Club and entering the Highveld suburb, where it meets the southern terminus of the M19 (John Vorster Drive, which connects to the Centurion CBD). Still named Nellmapius Drive, the M31 proceeds westwards from Highveld to meet the M36 before flying over the N1 highway (Ben Schoeman Freeway) and entering the Rooihuiskraal suburb.

Just after the N1 overbridge, the M31 reaches a junction with the R101 route (Old Johannesburg Road). It proceeds westwards through Rooihuiskraal as Uitsig Drive for 2 kilometres to reach its end at a junction with the M37 (Rooihuiskraal Road).
