The developers are not yet committing to an exact line - they are deliberately avoiding fixing the path of the road so that they can allay people's fears with comments such as "we will take that into consideration when we decide the final alignment". However, the broad path of the road is shown below.
The Wetlands bisected
In the picture below you can see how False Bay is fed by several rivers that are filtered by wetlands. If these wetlands are damaged, the flow of unfiltered water into False Bay itself will affect fishing around the Cape, the quality of the beaches, and the recreational capability of the Marina Da Gama.
The road passes between the Waste Water treatment works and the Rondevlei reserve. The birds that breed in the Reserve, would need to cross over the 6-lane highway to get to their feeding grounds in the treatment works. These are large seabirds, that are likely to fly low into the South Easter en route to their feeding grounds. The ornithologist for the environmental consultants says that birds can always fly somewhere else. Where else is left within a 1000 kilometers?
The area just north of the Zandvlei wetlands is the last remaining feeding ground of the Western Leopard Toad. By pouring a highway over this part of the Zandvlei Nature Reserve, the reserve loses viability for these toads and for several land-based species (duiker, tortoise, mongoose and various plants). The road will exterminate the Western Leopard Toad. The Zandvlei reserve is also frequented by the Cape clawless otter, and this very shy creature will not tolerate this destruction of its habitat, nor the air and water pollution associated with a highway.
