Nei Grigioni prendono il via i lavori per la costruzione di un nuovo tunnel ferroviario sotto il Passo dell'Albula.
E' stata una cerimonia sobria, cominciata senza nessun colpo di piccone ma con la posa di uno strumento di misurazione a poca distanza dagli scavi, con pure alcune riflessioni su quanto costruito oltre cento anni fa.
L'attuale traforo di 6 chilometri è stato aperto all'inizio del secolo scorso e l’incontro ha sollecitato qualche paragone sulle tecniche costruttive di allora rispetto a quelle odierne. La nuova galleria costerà 345 milioni e sarà terminata nel 2020.
