Amsterdam: Underground Instability

It’s possible to get almost anywhere in Amsterdam by foot, tram, bus, and, of course, the trusty Dutch bicycle. Since 2003, the city, recognizing a need for speedier transit, has been digging for a subway. In a city lined with canals and soggy earth, a dig of this sort presents some unique challenges.

Yesterday’s Boston Globe had an interesting look at the logistics. Let’s just say that Amsterdam is a “city in motion”…

Most of Amsterdam is supported by a system of underground wooden poles and pilings, and the land itself tends to shift and sink a couple millimeters a year. And if digging wasn’t a big enough problem, large, rumbling trains could affect this delicate balancing act once the subway’s up and running.

Best of luck with your dig, Amsterdam. We wish you stability.
