The iconic 135m diamond pylon of the 1.2km Kruununvuori Bridge is nearly at deck height.

The bridge, Finland’s tallest and longest, will be for use only by public transport trams, pedestrians and cyclists; but it is also designed with access for emergency vehicles.

The design by Knight Architects and WSP Finland includes an iconic diamond pylon, which is presently being concreted, as we reported last year (link opens in new tab). The main contractor for the project is a joint venture, TYL Kruunusillat. It consists of YIT Suomi and Kreate. Steel structures on the bridge are by Nordec.

The bridge will open to trams in 2027, and it may be opened slightly earlier to foot and cycle traffic. It is one of five new bridges in Helsinki’s Crown Bridges project.
