Plans for a £64 million bridge designed by Knight Architects in Helsinki, Finland, have been approved
The bridge is the centrepiece of a wider £222 million scheme, called Kruunusillat, which is being drawn-up in collaboration with WSP Finland. It will be nearly a mile long (0.7 miles) and run across the Kruunuvuorenselkä bay in Helsinki.
Once completed, it will be the longest bridge in Finland.
The structure will provide a crossing for pedestrians, cyclists and trams from the Kruunuvuorenranta development to the east of the capital - a scheme providing 580,000m² of residential space and 6,000 housing units by mid-2020 - to the city centre.
Knight Architects won a design competition to land the project in 2013. The proposals by the bridge specialists include a central, 135m-tall pylon with symmetrical cables attached.
Tom Osborne, an associate at Knight Architects, said: ’[The bridge] will extend Helsinki’s excellent public-transport system, significantly reduce journey times, and create a critical link to new developments.
’This will be a high-quality, lasting piece of infrastructure, which will be instantly recognisable and synonymous with Helsinki. We look forward to progressing the design with WSP Finland.’
Construction is due to start on site in autumn 2018, with the tramway set to be opened in 2025.

The design makes direct reference to the historic crown ownership of the bay area: the distinctive form of the central 135m pylon of the symmetrical cable-stayed design is a tall slender diamond, with multi-faceted surfaces designed to catch light and shadow both by day and night.
