The Making of Calatrava's Bridge in Seville

Cultural icon, daring engineering spectacle, and highly controversial structure, the Alamillo Bridge stands almost 150 meters tall, with an inclined pylon whose own weight balances that of the deck and traffic. Built for the 1992 Universal Exposition in Seville, Spain, the bridge immediately received great international attention that continues to this day.Santiago Calatrava received a direct commission to design the bridge and seized the opportunity to create a design breakthrough -- a stunning, harp-shaped bridge that defies both gravity and traditional bridge design.
