The project includes the setting up of both the input and output ramps for the construction of the new Chiomonte interchange on the A32 highway Torino-Bardonecchia. The ramps are on a viaduct and are connected to the highway at the Viadotto Clarea, a P/C viaduct on continuous beam with variable inertia, pre-stressed by post-tensioned cables, made with precast ashlars.
The decks, on a curvilinear layout, are in a steel-concrete mixed structure with the static scheme of a continuous beam on multiple supports and spans from 40 up to 50 meters long. The standing piers are up to 47 meters high.
In addition to the two ramps, the project also includes two mixed-structure decks, the first one with three spans of 35 meters and the other one with a single span that is 41 meters long.
