Collegamento tra A2 e A13: l’ultimo studio di fattibilità dell’USTRA rivaluta la variante “pianura”, quella che si sviluppa parzialmente in parallelo alla linea ferroviaria.
Ha il migliore rapporto costi-benefici, può essere eseguita a tappe nel più breve tempo di costruzione, risulta vantaggiosa secondo i criteri di valutazione qualitativi, gode del sostegno di tutte le parti interessate e comporta costi di costruzione minori (1'023 milioni di franchi, ai prezzi 2010).
Le altre due varianti tutt’ora in gioco sono quella "strada esistente" e la variante "libera" che prevede una galleria tra Cadenazzo e Quartino.
Per motivi di sicurezza lo studio prevede infine gallerie a canne separate.
Il Consiglio di Stato ha ora trasmesso l'incarto all'autorità federale affinché venga integrato con carattere prioritario nella pianificazione dei futuri interventi realizzativi sulla rete delle strade nazionali.
