La tenuta dell'importante ponte di Riddes, opera nevralgica per la mobilità regionale, preoccupa il Vallese. Stando a quanto riportato dal quotidiano Le Nouvelliste, l'autorità cantonale ha deciso lunedì di proibire il transito ai veicoli superiori alle 3,5 tonnellate.
Il responsabile dei servizi della mobilità, Vincent Pellissier, non esclude uno scenario di chiusura totale, una volta che saranno noti i risultati dei nuovi esami predisposti sull'opera.
Secondo le prime stime, una ristrutturazione costerebbe 22 milioni di franchi, di cui 8 a carico del cantone. L'intervento sarebbe però problematico, come succede per i ponti costruiti negli anni '60-'70. Secondo Pellissier non si può perciò escludere che l'opera vada completamente rifatta. Questo comporterebbe un onere di 80 milioni di franchi.
