During the month of July 2016 Arianna lit up the road junction in the S.S. 318, near the municipality of Perugia, as part of the project “Quadrilatero Marche-Umbria”.
In detail, the installation of public lighting has been realized next to some critic points, represented by the crossroads of the junction between Pianello and Valfabbrica. Its purpose was the increase of the security level during the night circulation. The road junction near Pianello includes only acceleration and deceleration lanes, while the one in Valfabbrica features also a roundabout.
