The Norwegian Road Authority Nye Veier and BERINOR ANS, a joint venture of BESIX and Rizzani de Eccher, have signed a contract for the next phase of the world’s longest bridge using structural timber.

Under the contract, the partners will be responsible for the design and development of the E6 Moelv-Roterud infrastructure project.

The project will include a 1km main bridge over Lake Mjøsa, along with an 11km section of four-lane motorway.

The bridge concept will involve sustainability aspects such as limited greenhouse gas emissions and quality landscape integration.

BESIX and Rizzani de Eccher are working with the Norwegian contractor AF Gruppen, the designer and consultant Multiconsult and architect Knut Selberg for the project.

BESIX Europe area manager Nic De Roeck said: “This is an important step in the project we signed today. It allows us to move forward together towards the realisation of a bridge that will be remarkable and unique, especially from a technical and environmental point of view.

“I look forward to the dynamism and professionalism of the collaboration, which all project stakeholders are enthusiastically signing up for.”

Last September, BESIX and Rizzani de Eccher collaborated to successfully execute the Crown Princess Mary Bridge (Kronprinsesse Marys Bro) in Denmark ahead of schedule.

The project included an 8.2km four-lane motorway and a 1.4km bridge over the Roskilde fjord.

This January, Swedish construction firm Peab secured a contract valued at Nkr784m ($80.8m) from Nye Veier for the extension and maintenance of the E6 highway between Kvål and Melhus in Norway.
