The construction of this bridge will cost 240 million euros and could be completed in 2025


By 2025, the longest wooden bridge in the world may be finished. It will be built in Norway, it will be more than a kilometer long. Let’s see it together.


# The record bridge

The longest wooden bridge in the world will be built by the Berinor joint venture, which includes the Italian company Rizzani de Eccher of Udine and Besix of Brussels.

The Norwegian road authority Nye Veier chose the Berinor joint venture above all candidates for the attention to sustainability which is the fulcrum of this project.

The two companies appear to be a winning couple, in fact they have already collaborated previously for the realization of other important projects and firsts in Europe, including the Crown Princess Mary bridge in Denmark, which included a four-lane highway of 8.2 kilometers. and a 1.4 kilometer bridge over the Roskilde Fjord.

Their new record-breaking project could mark the future of the sustainable construction field.

# The structure


The project consists of the design and construction of the section of the E6 motorway between the towns of Moelv, north of Oslo, and Roterud.

The project involves the extension of the highway, the construction of a new infrastructure and the arrangement of some nodes represented by several bridges and underground channels.

The length of the bridge will exceed one kilometer and will be part of the 11-kilometer four-lane motorway section.

The E6 Moelv-Roterud infrastructure project will be the longest structural timber crossing in the world and will be a benchmark for the use of sustainable materials in major infrastructure projects.

The structure includes foundation piles in steel, reinforced concrete foundations with rounded arched pillars but the entire load-bearing structure will be in wood.

Where did the choice of this material come from?

“We had to design an infrastructure that was both light in its form, sustainable from an environmental point of view and strong from a constructive point of view. We therefore thought of a structure that would also have a low environmental impact in terms of CO2 emissions: the intensive use of wood makes it possible to achieve these three objectives “, these are the words of Gilberto Dreas, Rizzani de Eccher technician.

# The bridge above the lake


The wooden bridge will rise over Lake Mjøsa, the largest lake in Norway which with its 80 meters is also one of the deepest in Europe.

Building a bridge above a lake has brought with it some precautions, it has made it necessary to find solutions capable of minimizing the effects of water pollution and emissions produced by the use of barges and boats.

The bridge will be built from below and involves the use of poles ranging up to 80 meters deep.

The goal of this project is to create a structure that has sustainability as its main value: they want to limit greenhouse gas emissions and integrate the bridge into the surrounding environment and wood seems to be the perfect material for this.

The construction of this bridge will cost 240 million euros and could be completed in 2025.
