Executive design and assembly of steel bridges.
The works include the creation of approximately 1.1 km of expressway between the Stalingrad interchange of the current South III expressway and the left bank access viaduct to the Flaubert bridge.

This new portion notably includes three reinforced soil embankments and two engineering structures, including a railway crossing.
The Madagascar structure consists of two separate decks: the east deck is 13.50 m wide and the west deck is 12.68 m wide. The total length is 116 m over 3 spans 36 m + 44 m + 36 m.

The layout is partly straight and partly curved; the longitudinal profile is a ramp with a constant slope. Each deck is made up of 2 metal beams 1.70 m high; the metal beams are reconstituted welded profiles.
The beams are connected to a fully prefabricated reinforced concrete slab 30 cm thick. Each beam rests on a laminated elastomer bearing. Four of the metal spacers are used.

Common type except C5-C6, C11 and C12, C5-C6, C11 and C12 type (before and after pier spacers), pier type and abutment type. The framework of the deck will be assembled on site and then moved by SPMT and, finally, set up by crane using pairs of cranes. Once the deck has been placed on temporary supports, the prefabricated slabs will be put in place. The deck will be completed by concreting the keying strips and completely deck finishes and equipment.
