Infrastructure branch Making all the difference

Leader in the engineering structures sector

Eiffage Infrastructures is an international player recognized for its ability to carry through all types of engineering project via the brand names Eiffage Génie Civil and Eiffage Metal, in France, Smulders in Belgium, SEH in Germany, ICCI in Canada and Puentes y Torones in Colombia.

From simple truss bridges to complex viaducts, we have the design, engineering, works and maintenance skills to meet our clients' expectations and their requirements in terms of cost, deadlines and quality.



    We have in-depth expertise in design and build projects with reinforced and prestressed concrete, steel or a concrete/steel mix frame.


    Since the construction of Millau Viaduct, our specialist roads, civil engineering  and metals teams have developed extensive experience in working together to ensure the success of the project.


    We hold a key position beyond the borders of Europe, thanks to our African successes (Faidherbe Bridge renovation in Senegal and structures in Madagascar) and our Canadian and Colombian subsidiaries.

Road, motorway and rail structures Road, motorway and rail structures

Eiffage Génie Civil is responsible for the most significant French engineering structure projects, such as Millau Viaduct, Normandy Bridge and Gustave Flaubert vertical lift bridge in Rouen and the many structures built on the country's high speed rail lines.

Our teams are able to operate at design stage, taking charge of both preliminary studies and construction on bridge, viaduct, footbridge and other engineering structure projects.

Eiffage Infrastructures' teams of experts can meet the needs of all types of steel, concrete and mixed structures including cantilevered, incrementally launched, mixed, cable-stayed, suspension, vertical lift and modular bridges, steel bridges with orthotropic decks, and footbridges.

Innovation et ouvrages d'art

Innover par les matériaux ou par les structures, tel est le défi quotidien des équipes. Maîtrisant parfaitement les techniques traditionnelles, elles sont aussi capables de proposer des ouvrages d’exception. Grâce à l’utilisation de matériaux innovants,  BSI®, précontrainte, aciers à très haute limite d’élasticité, polymères renforcés…, les équipes de la division Ouvrages d’art proposent des solutions inventives dans le respect des contraintes environnementales.

  • Ponts à poutres métalliques : les poutres métalliques reconstituées soudées (PRS) sont largement utilisées pour la construction d’ouvrages métalliques ou mixtes. À partir de tôles, on reconstitue une poutre en forme de I. On peut ainsi constituer des poutres de résistance parfaitement adaptées a chaque ouvrage. Ce produit est utilisé massivement pour la construction des ouvrages routiers, autoroutiers ou ferroviaires.
  • BSI® : le BSI®, Béton Fibré à Ultra hautes Performances (BFUP), et grâce à ses performances mécaniques exceptionnelles, a permis le développement de nouveaux concepts de tabliers de pont ultra minces (Poutres en I à talon élargi : ITE®), et de nouvelles techniques innovantes de renforcement d’ouvrages (Procédés Orthodalle, R6Pont…).


  • Hochmosel  Viaduct - Germany
    Hochmosel Viaduct - Germany

    This viaduct will cross the Moselle Valley and will require 33,000 tonnes of steel. It has a steel box girder structure with an orthotropic deck and is 29 m wide and 1,700 m long, with a maximum span of 210 m. The apron will rise to over 150 m above the valley, and was put into place by incremental launching, a process already tried and tested on Millau Viaduct.

  • Kamoro Bridge - Madagascar
    Kamoro Bridge - Madagascar

    This structure is a suspension bridge on the River Kamoro, comprising a large 206.5 m span. It will continue the island's major north-south axis, national highway RN4, which the existing structure is no longer able to do. The apron has a mixed framework and comprises  a steel mesh of main beams topped with a substrate of prefabricated concrete slabs.

  • Grande Chaloupe Viaduct - Reunion Island
    Grande Chaloupe Viaduct - Reunion Island

    This structure, 239 m long by l29 m wide and comprising 4 spans, is located offshore on a particularly sensitive site. The deck is a 4-web single prestressed concrete box girder built in  cantilevered segments using the mobile rig.
