The national highway company NDS confirmed the information of the opposition party OĽaNO that Italian firm Salini Impregilo is laying off 160 workers from the building of the Višňové highway tunnel between Žilina and Martin. NDS is “concerned”, but can’t influence the move. OĽaNO alleges Salini Impregilo is leaving the project altogether, to minimize its losses. The tunnel might be delayed further. Dúha, which is building the tunnel in a consortium with the Italians, did not comment on Thursday.
