Amsterdam To Build Underground City Beneath Canals
To help relieve some of the pressure from overcrowding and soaring land prices, Dutch engineers have recently unveiled plans for an underground city to be constructed below Amsterdam, beneath the canals. The £7.4 billion project, called Amfora, will eventually materialize into a six level, one million square foot subterranean city, complete with retail, leisure and parking facilities.
Because Amsterdam was originally built on drained marshland and many of the cities classic houses still sit upon aging wooden beams, it was decided that building down was the best option. The plans call for the water in the canals to be temporarily pumped out while a combination of natural clay and concrete will be used to reseal the canal floor, making it possible for the water to pour back into the canals and for construction to safely continue below.
