This short suburban pass dates back to Johannesburg's early pioneering gold rush days and is one of only a handful of official passes in South Africa that are shorter than 1 km. Within that 900m of distance you will experience gradients as steep as 1:7, a full hairpin pin and many very old dressed stone walls on either side of the road. It connects Upper Houghton with Houghton. The low, rocky ridge that separates downtown Johannesburg from the northern suburbs is called Linksfield Ridge and this little pass is one of three that were first built to give residents of a rapidly expanding city, access to new places to live to the north. The other two are Stewarts Drive and Sylvia's Pass. The ridges cutting through Yeoville and Observatory/Linksfield are a natural barrier between the northern and southern areas of Johannesburg. These ridges were first populated in the late 1800s and early 1900s.
