The design pays particular attention to:
A) Road safety and function;
B) Links with the existing road network;
C) The structures required (in particular the Sangone Torrent crossing consisting of a three bay bridge with central span of 65 meters and bank spans of 43 meters);
D) Site organization and relevant building stages to avoid negative repercussions on the road network affected;
E) The "earth moving balance" (use of ground stabilization techniques with lime in order to reuse material from the excavations to build road embankments);
F) Environment, with special focus on the preservation of surface and underground water, sound mitigation and landscape setting.
