"There was no collapse of plaster nor of concrete in the Quiliano tunnel on the A6, only a small cloud of paint dust detached from the side of the tunnel occurred". Autostrada dei Fiori, the company that manages the A6, explains this, further specifying that the tunnel "has never been closed".
The A6 is the same highway where, on 24 November, a piece of viaduct collapsed overwhelmed by a landslide.
