The R29 is a provincial route in South Africa that connects Johannesburg with Leandra and Kinross via Germiston, Boksburg, Benoni and Springs. For much of its route it is named Main Reef Road. The R29 used to end near the Golela border post, however the section from Evander to Ermelo is now part of the N17 (prior to construction of the N17 extension from Leandra to Evander, the N17 followed the alignment of R29 from Leandra; however, the extension of the N17 highway has resulted in the old section of the road being given to R29) and the section from Ermelo to the Golela border post just after Pongola is now part of the N2.
