The architectural image is one of a tree-lined city street, with a row of metal “trees” whose branches cover Viale Galli and the lateral ends of the motorway, with a maximum height of 8.50 meters. These modular elements in tubular steel varying in diameter and with cast-iron joints, are aligned with a centre distance of 10.50 meters. The foliage and the slanted walls are made of sound-proof panels with 18-mm Plexiglas.
