Crown Bridges granted first environmental permit
The Regional State Administrative Agencies of Finland granted the City of Helsinki a permit on 5 January 2017 to build two of Kruunusillat – the Crown Bridges – between Nihti and Kruunuvuorenranta, to dredge and fill the local sea area, and to build the necessary structures on shores.
The Finkensilta bridge connecting Nihti (in Sompasaari) and the Korkeasaari island (home of Helsinki Zoo) will be a beam bridge constructed of reinforced concrete and supported by eight piers. The span will be about 300 metres. The Kruunuvuorensilta bridge connecting the Korkeasaari island and the Kruunuvuorenranta area in Laajasalo will be a single-pylon, cable-stayed bridge spanning about 1.2 kilometres.
Construction in accordance with the environmental permit can be commenced once the detailed plan of the area is legally binding.
The Crown Bridges project will give the growing district of Laajasalo in eastern Helsinki a smooth public transport connection to the city centre. The bridges will serve trams, cyclists and pedestrians but no cars. The project involves 10 kilometres of trams lines, a cycling connection, pedestrian paths and plazas.
The project will improve connections in the entire Helsinki region, as it will form an integral part of the region’s public transit rail network and cycling network.
The most visible part of the Crown Bridges project will consist of three new bridges, the longest one of which, the Kruunuvuorensilta bridge, will be the longest bridge in Finland.
