26 1 Innovations and nuances The City of Helsinki organized an international design competition City Council's decision The winner was a cable-stayed bridge. An undeniable merit of the entry is the openness of the underside of the bridge, which diminishes its intrusive effects on the landscape. The purpose of the competition is to find a first-rate solution for the extremely demanding environment.. The bridge should be part of Helsinki s heritage to future generations.. The winner bridge Gemma Regalis was design by a Finnish- British team coordinated by WSP Finland. 4 6 Esityksen / Esittäjän nimi
