The development of roads, starting with the invention of the wheel, is briefly traced. Th e development of geometric design, specifically as reflected by changes in design manuals, starting with the motor car leads into discussion of the specifics of manual development in South Africa. Published documents up to the SANRAL G2 manual, published in 2002, are addressed. Dramatic changes in the philosophy of geometric design in the last fifteen years amount to paradigm shifts of note. These include a substantial increase in the adoption of human factors in design, the Contest Sensitive Solutions approach to design and a broader understanding of the environmental issues that impact on and are impacted by the provision of roads. The publishers Taylor and Francis are developing a text titled The geometric designer's handbook, which is due to be published towards the end of 2014, addressing these issues. This will hopefully support the adoption of current research by practitioners and enhance general understanding of the new philosophy of design.
