Back in July 2016, as part of the “Quadrilatero Marche-Umbria“ project, Arianna illuminated the junctions along the SS 318 state road, in the municipality of Perugia.
In particular, public lighting systems were built at the critical points, represented by the intersection areas in the two Pianello and Valfabbrica junctions, in order to increase the level of safety during road use at night. The two junctions in question include acceleration and deceleration lanes, and the Valfabbrica junction also features a roundabout illuminated by a lighting tower.
