A colossal pedestrian bridge has opened near Helsinki, Finland, claiming the title of the world's longest bridge dedicated exclusively to trams, pedestrians and cyclists. The 1,200-metre (4,000ft) structure connects the islands of Laajasalo and Korkeasaari, and is also Finland's tallest bridge.
Designed by British firm Knight Architects, the Kruunuvuori Bridge cost €150 million (£126 million) and is part of a £505 million project extending the tram network by around six miles from the city centre to Laajasalo, where a new housing development is under construction. An average person can walk across in about 15 minutes.
Architect Tom Osborne said the bridge's central diamond tower is a major new addition to Helsinki's skyline and a catalyst for sustainable growth. The structure's width varies from 49 to 62 feet, with a 65-foot maximum clearance. Designed to last 200 years, it incorporates features to withstand harsh Finnish winters, including stay cables that remain in slight motion to prevent ice buildup and a wind warning system.
Osborne highlighted the bridge's long-term perspective: 'Taking a 200-year position on the returns of that investment – in both financial and climate terms – shows that big projects need to be paired with a long-term view.' The bridge prioritises sustainable movement, redefining its role from transport infrastructure to a civic space.
