Sailing in and immersion of tunnel elements Noord/Zuidlijn

In September and October 2012, the last connection of the Noord/Zuidlijn metro line (a new metro line that will connect the North and South of Amsterdam) was made: the tunnel under the IJ River. The gap between Amsterdam-Noord and Amsterdam Central Station was closed over a span of three consecutive Tuesdays.
