Madagascar Overpass (France)

Today we share with you one of our works carried out in France.

The project includes the executive design and the assembly project of the Madagascar overpass, a left bank access work to the Flaubert bridge included in the project for the construction of approximately 1.1 km of highway between the Stalingrado junction of the current Sud III highway.

The structure is composed of two separate decks: the east deck is 13.50 m wide and the west deck is 12.68 m wide. The total length of the structure is 116 m on 3 spans 36 m + 44 m + 36 m. The route is partly straight and partly curved. Each deck is made up of 2 metal beams of constant height and equal to 1.70 m and prefabricated concrete pre-platforms. The deck constraint system is composed of reinforced elastomer bearings. The framework of the deck was assembled on site and moved by SPMT. The macro-segment composed of the two beams and the crosspieces is positioned at height, on temporary supports, by tandem lift. Once the deck was positioned, the prefabricated slabs were installed. The deck was completed by closing the joints of the slabs by casting in place and finally the finishing works were carried out.

We had already shared a video on our Youtube account, which you can watch again HERE.

The video https://www.acces-pontflaubert-rivegauche.fr/fr/actualites/video-mise-en-place-du-viaduc-madagascar that we are sharing today, however, was published on the site https://www.acces-pontflaubert-rivegauche.fr/, and shows not only the work itself, but also the technicians and operators involved in the various phases of construction of the viaduct. Enjoy!
