The construction of the new Noord/Zuidlijn (North/South metro line), which will improve transport links between the north and south of Amsterdam, means that large parts of the city centre are less readily accessible. The digging work was started in several places at the same time, so that things would proceed more quickly.
The Amsterdam metro system
Amsterdam’s metro network is recent. The first metro lines were only laid in 1977. Most of those lines led to residential areas outside the centre, so there remained a need for a metro line that would pass under the city centre. That was a problem, because Amsterdam was built on swampy ground. Every building in the city centre is supported by wooden posts driven deep into the ground. A metro network would have to be tunnelled under those posts. That was - initially – considered technically and financially unfeasible.
The Noord/Zuidlijn complete
In the end, the decision was taken to construct the Noord/Zuidlijn – a metro line running from the northern part of Amsterdam under the river IJ to Central Station. From there it will continue to Dam square, and then via Rokin on to Station Zuid/WTC. The actual construction work began in 2003. It was expected that the 9.2km-long line would be completed by 2011. That proved to be unfeasible. After the opening date having been postponed eight times, the metro line will officially open on 22 July 2018.
