Bridge across the Fontaine gully - on the Reunion island

The gap is formed by a 110 m deep gully at the bottom of which no support can be built.
The bridge is a 200 m long arch bridge.
The unique arch is made up of steel and has a 170 m span. It supports a composite deck (steel and concrete) by means of radiating steel columns.
The foundations are composed of concrete massifs casted in two indentations made in the gully banks.
The arch has been built with the cantilever method from each bank with a truss made of temporary diagonals and by anchoring the strain component with active anchors in the ground.
