A new study shows how an aluminium bridge could be a cost-efficient and climate-friendly alternative for the new coastal highway in Norway. Hydro and an external team of renowned structural engineers, business experts and researchers have investigated the feasibility and cost of replacing conventional steel with aluminium as a construction material for long-suspension bridge girders. The proposed Langenuen bridge, part of one of the largest infrastructure projects in Norway, the new E39 Coastal Highway Route, aims to reduce travel by replacing ferries with bridges, among other things. The “Langenuen suspension bridge – Aluminium bridge girder alternative” report demonstrated that it’s possible to save time and money on production, material and maintenance by switching from steel to aluminium. Moreover, the technology could potentially be used in other suspension bridge girders.

The report was created by the independent structural engineering consultancy Dr.techn. Olav Olsen, Hydro, leading EPC (engineering, procurement and construction) supplier Leirvik AS and the Norwegian University of Science and Technology (NTNU). DNV GL has also been involved as a third-party verification agency.

Now the project team goes into a phase 2 to review the remaining technical questions and methods to deem whether the project could be a reality.
