Dissing+Weitling is part of the team picked for developing the preliminary project for a suspension bridge solutions for crossing the Sula Fjord and for a suspension bridge across the Halsa Fjord.

  • As bridge design experts, Dissing+Weitling will work together with Aas-Jakobsen, COWI and Multiconsult with Johs Holt to assist the Norwegian Public Roads Administration in developing the best bridge solutions for the E39 where it crosses the Sula Fjord and Halsa Fjord. The consultancy team has been awarded five in eight preliminary projects for the two fjord crossings in Møre and Romsdal.

    - It is a great pleasure to be able to continue our work in Norway. This exiting task is a continuation of the great collaboration on the Bjørna Fjord bridge and the team's experience gained through our involvement in advanced long-span bridges, floating bridges and marine structures in Norway and abroad. The bridges will be located in a dramatic and magnificent scenery, and for this reason, it is our goal to design the bridges in respect of the natural surroundings, says Partner and Architect Jesper Henriksen.

    The Bjørna Fjord floating bridge contains a lot of new technical breakthroughs.
  • Pushing boundaries

    The project is beyond any kind of standard solutions and requires expert skills within transportation and bridges, offshore and other marine projects as well as the developing new technology:

    - We won thanks to the solid solutions we presented and our team’s unique competencies, and we’re very delighted to be recognised by the Norwegian Public Roads Administration. It’s a feather in the cap of the entire consultancy team’s bridge specialists, and now that we’ve signed the contract, we are excited to get started, says Erik Sundet, Vice President of Bridges and Geotechnical Disciplines in COWI in Norway.

    The Sula Fjord spans from Hareid and Sula and measures between 3.5 and 4.0 kilometres in width and down to 450 metres in depth where the bridges will be located. The section is exposed to severe winds and waves.

    The depths of the fjords

    The team will explore different solutions and depending on the final result, this may be the longest bridge span in the world on a suspension bridge; the Halsa Fjord is a so called fjord arm in Nordmøre district, measuring two kilometres in width and 500 metres in depth at the future bridge location. For this location, the consultancy team will explore a concept for a two-span suspension bridge on a floating foundation in the middle of the fjord, anchored to the fjord bed.

    The study of the different concepts will start in May and must be completed by 1 April 2022.
