Talk:R21 (Gauteng)

From Wikipedia, the free encyclopedia

[edit] P157

The R21 is referred to as the P157 in official documentation, and on the signs on the side of the road. The section closer to Pretoria is called the P157-1 and the section closer to the airport (past Olifantsfontein) seems to be the P157-2. Someone who understands the significance of this alternative numbering scheme for roads (K and P) should add that detail to the article. 168.209.98.35 20:11, 10 February 2006 (UTC)
