Ci sarà una sola corsia di marcia per ogni canna, dopo l'apertura al traffico del secondo tubo autostradale sotto il San Gottardo e dopo il risanamento di quello vecchio.
La precisazione è arrivata lunedì per iscritto direttamente dal Governo, nel quadro della tradizionale ora delle domande al Consiglio nazionale. La seconda corsia, d'emergenza, non potrà essere utilizzata neppure in modo temporaneo. Anche per un uso provvisorio occorrerebbe modificare la Costituzione, ha spiegato l'Esecutivo rispondendo ad un'interpellanza della deputata Regula Rytz (Verdi/BE).
Oltre alla modifica costituzionale - aggiunge il Consiglio federale - occorrerebbe anche cambiare la Legge federale sul transito stradale nella regione alpina (LTS), appena accolta in votazione. Modifiche in questo senso sono, per il Governo, "fuori discussione".
