Lunedì sono iniziati i lavori di costruzione del cunicolo di drenaggio a Brienz/Brinzauls (GR), il paese minacciato da una frana. Il sistema misurerà 2,3 chilometri e dovrebbe proteggere il villaggio da ulteriori danni causati da frane e caduta di massi. Lo ha reso noto oggi il comune di Albula/Alvra, a cui appartiene Brienz.
Dopo i lavori di preparazione del cantiere, i primi brillamenti sono programmati per fine maggio. I lavori di perforazione dovrebbero durare fino all’estate 2026; le trivellazioni saranno completate nell’estate 2027. L’appalto è stato vinto da un’impresa ticinese.
Il costo dell’intero cunicolo è circa 40 milioni. Il Cantone e la Confederazione si faranno carico di 18 milioni ciascuno; i restanti 4 milioni saranno suddivisi tra il Comune e i proprietari di strade e tubature.
