The article presents information on the structural design of the Bridge Pavilion in Zaragoza, Spain. The bridge, conceived by architect Zaha Hadid, places particular emphasis on water and sustainable development. The bridge's undulating form evokes images of waves or ripples on the surface of a river, while the exterior cladding resembles the skin of a shark. It spans 270 meters long and widens from 5 meters to as much as 30 meters. Its foundations take the form primarily of 22 drilled piles, 4 of them on the south bank, 8 on the north bank, and 10 beneath the central pier.
