I lavori per lo scavo della seconda galleria autostradale sotto il San Gottardo, approvata da popolo e cantoni, cominceranno nel 2020, secondo la migliore delle ipotesi.
Doris Leuthard ha tracciato a grandi linee le prossime tappe, che prevedono l’elaborazione di un progetto da parte dell’Ufficio federale delle strade, in collaborazione con cantoni e comuni interessati. Dopo il via libera del Consiglio federale si procederà al rilascio dei permessi di costruzione, ed è proprio in questa fase che si rischia di accumulare ritardi.
La durata dei lavori di costruzione è stimata a 7 anni. Dal 2027 potrà dunque aprire il nuovo tunnel e si potranno avviare i lavori per risanare quello esistente. Il Governo conta, entro il 2030, di avere a disposizione due gallerie, una nuova e una risanata.
