The N21 is a proposed national route in South Africa in Cape Town. It mainly forms the Peninsula Expressway ring road. Once complete, it will link the northern suburbs on the Atlantic seaboard (Melkbosstrand & Bloubergstrand) with the southern suburbs on False Bay (Muizenberg). The R300 Freeway is entirely part of the proposed route (the freeway will be extended at both ends). Background Proposed Route The proposed freeway will include sections of the existing R300 freeway and will be tolled. The name of the consortium involved in the construction of the Expressway is "Penway", short for Peninsula Expressway. The Penway has also become the local nickname for the Expressway. Explosive growth of the Cape Town metropolitan area, especially in terms of local and international tourism, the wine industry, and the film industry, has pushed the traffic situation to a critical point. Environment A number of environmental impact studies have been done, to determine whether new sections of the freeway will upset the delicate ecological systems in the Cape Town area. New sections will run south of the N2 towards Zeekoevlei, which is a wetland area, and north of the N1, up to the area near Melkbosstrand. Projects Project R300 During the 1990s and 2000s, the national road agency and Western Cape Department Of Road And Transportation began the final construction of the R300, the first section of the highwa.y Project N21 The Peninsula Expressway will have junctions with three National Roads, the N1, the N2, and the N7 as well as the M3 and the M5 which are Cape Town metropolitan freeways. The proposed N21 project requires upgrading the current R300 Road as well as joining it to the N7 highway to form the ring road. Opposition The Project to extend the R300 has been opposed by some members of society due to them wanting to preserve the areas in which the proposed road is meant to pass (such as wetlands & sanctuaries).
