Peninsula Expressway (Cape Town)

The Peninsula Expressway is a proposed ring road around the city of Cape Town, South Africa. It will link the northern suburbs on the Atlantic seaboard with the southern suburbs on False Bay. Known as the N21, the 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.

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.

A number of environmental impact studies have been done, to determine if 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.

List of bus routes in Nassau County, New York

The following bus routes are operated in Nassau County, New York. Most of these routes are operated under Nassau Inter-County Express (NICE), formerly MTA Long Island Bus, except in Greater Long Beach, where that city operates its own bus service through Long Beach Bus. Some of them are the direct descendants of streetcar lines (see List of streetcar lines on Long Island and in Queens), and most were previously privately operated prior to 1973. These routes are designated on the buses, bus stop signs, and timetables with a lowercase "n". Previously, the routes were designated with an uppercase "N", akin to routes in bus systems surrounding the area. Note that the buses purchased secondhand from Foothill Transit still display the uppercase "N" on their signs.
