The R24 is a major East-West provincial route in the Gauteng and North West provinces that links OR Tambo International Airport with Rustenburg via Johannesburg, Krugersdorp and Magaliesburg. The process of renaming the streets and freeway that form the route from Krugersdorp eastward to OR Tambo International after anti-apartheid stalwart Albertina Sisulu was completed in 2013.

Provincial routes are the second category of road in the South African route-numbering scheme. They are designated with the letter "R" followed by a number from 21 to 82, formerly with the letter "P" followed by a number from 66. They serve as feeders to the national routes and as trunk roads in areas where there is no national route.
