Spijkenisse (Dutch pronunciation: [spɛikəˈnɪsə] ) is a large town in the province of South Holland, Netherlands. Following an administrative reform in 2015, it is part of the municipality of Nissewaard, and has a population of 72,500. It covers an area of 30.27 km (11.69 sq mi) of which 4.15 km (1.60 sq mi) is water. It is part of the Greater Rotterdam area.

Zuidvleugel (Dutch pronunciation: [ˈzœytˌfløːɣəl], literally "south wing") is the band of cities and towns located along the southern wing of the Randstad in the Netherlands. It is that part of the Randstad that is located in the Province of South Holland. This developing conurbation extends around 60 kilometres from Dordrecht to Leiden. The two main focal points are the area around Rotterdam (called Rijnmond) and the area around The Hague (called Haaglanden).

With a population of around 3.5 million people, the Zuidvleugel is one of the largest urban areas in Europe.

The Rotterdam Metro (Dutch: Rotterdamse Metro) is a rapid transit system operated in Rotterdam, Netherlands and surrounding municipalities by RET. The first line, called Noord – Zuidlijn (lit. 'North – South line') opened in 1968 and ran from Centraal Station to Zuidplein, crossing the river Nieuwe Maas in a tunnel. It was the first metro system to open in the Netherlands. At the time it was also one of the shortest metro lines in the world with a length of only 5.9 km (3.7 mi).

In 1982 a second line was opened, the Oost – Westlijn (lit. 'East – West line'), running between Capelsebrug and Coolhaven stations. In the late 1990s, the lines were named after two historic Rotterdam citizens, the Erasmus Line (North – South) after Desiderius Erasmus and the Caland Line (East – West) after Pieter Caland. As of December 2009, these names were dropped again in favour of a combination of letters and colours, to emphasise and clarify the difference between the separate branches, especially of the former East – West line.
