Tunnels are “wounds” inflicted by mankind on natural topography to facilitate human movements. Their history is ancient, glorious and sometimes painful, but today techniques have been refined to the point of making their excavation similar to endoscopic surgery.
The tunnel Vedeggio-Cassarate that connects the area of the Lugano stadium to the Milan-Zurich highway became the new gateway to the city from the North pending the completion of the link to the new highway system: the entrance and exit from the tunnel needed a temporary arrangement to mask the structural works until the second phase of roadwork and their final landscaping.
A “ruled surface” (a curved surface obtained by the translation and rotation of rectilinear sections) moves in space adapting to the existing constraints. A large sinuous “screen” – reaching heights of ten meters and undulating between concave and convex forms – visually permeable or opaque depending on the points of view, it presents itself as an “environmental sculpture” displaying a temporary entrance to the city. A parterre of white pebbles conceals the wooden poles entering the ground, making every structural detail disappear in favor of the dynamic perception and the interplay of light and shadow at different times of the day as in a big sundial.
