MILAN (Reuters) - The CEO of Autostrade per l'Italia and Atlantia ATL.MI told Italian daily La Stampa on Friday that he felt responsible, but not guilty, for the deadly collapse of a motorway bridge operated by Autostrade.

When asked whether the government could revoke the motorway concession on the part of the network where the disaster happened, Giovanni Castellucci said it was not possible to separate that part of the concession from the rest.
