The new Kruunuvuori Bridge of Helsinki is an exceptional infrastructure project in terms of scale and execution, connecting Laajasalo with the city centre via light rail, pedestrian and bicycle routes. The bridge is a marked improvement to cross-city traffic in Helsinki and strengthens the competitivity of low-emission modes of transport while also providing a new, impressive marine landmark in the townscape.
With a length of 1191 metres, the Kruunuvuori Bridge is a composite cable-stayed and beam bridge with a concrete deck. Its pylon, rising to 135 metres, is a rarity in Finnish infra construction.
The development and use of advanced concrete technology in the project, such as special concrete types as well as real-time temperature and strength monitoring, aimed at a 200-year service life.
The construction stage was characterised by exceptionally precise design, challenging underwater concrete casting and consideration of the special conditions in an environmentally sensitive area.
According to the jury, the Kruunuvuori Bridge is an example of how technical quality, sustainable development, and architectural ambition can be combined in a large-scale infra construction project.
