Eiffage Génie Civil: launching the Langangen bridge

Infrastructures Division

On January 24, teams from Eiffage Norge, accompanied by Eiffage Metal, achieved this technical feat as part of the E18 Langangen Rugdvedt project. The 135 m bridge, weighing over 800 tonnes, is a feat of engineering.

The steel structures for the bridges are shipped to Larvik from Eiffage Métal's welding yard in Lauterbourg. On site, the elements are assembled and then pushed onto temporary structures, sliding on Teflon pads and skids.

The next step is to weld the following steel sections to the rear edge before repeating the process. Around 135 meters are pushed at a time, at approximately two-month intervals.

This bridge marks the start of a series of projects, demonstrating our contribution to the development of Norwegian infrastructure with Nye Veier AS.
