N21 (Cape Town)

The N21 is a proposed national route in South Africa in Cape Town. It mainly forms the Peninsula Expressway ring road. It links the northern suburbs on the Atlantic seaboard with the southern suburbs on False Bay. Known as the N21. Currently the ring road is partly complete with most of the road being a Dual carriageway, with parts of the N1 and N2 and N7 being a dual 4 lane freeway.[1]

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.[2]

Proposed Intersections

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.[1]

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[3][4][5]

Unfinished Freeways in Cape Town

The Foreshore Freeway Bridge, also known as Cape Town's Unfinished Bridge, is an incomplete section of what was intended to be the Eastern Boulevard Highway in the city bowl of Cape Town, South Africa. This is only one of the other examples left unfinished due to no funds. In recent years, after the economic growth with in the are, a new idea was proposed.[6][7]

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 highway[8][9]

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.[1] The proposed N21 project requires upgrading the current R300 Road as well as joining it to the N7 highway to form the ring road[8][10]
