Nella notte fra mercoledì e giovedì anche la Valposchiavo è stata colpita da colate detritiche dovute alle forti precipitazioni. Il materiale franato dalla Val Beton e dalla Val d'Urezza ha causato l'interruzione parziale della strada del Bernina.
I franamenti hanno iniziato a verificarsi presumibilmente verso le 23.00 di mercoledì, ha spiegato a Keystone-ATS Davide Zanolari, il responsabile della Polizia cantonale grigionese in Valposchiavo. Le colate di materiale fangoso sono precipitate dalla Val d'Urezza, poco sopra San Carlo, e dalla Val Beton, poco dopo il borgo di Poschiavo. Interrotto al traffico anche il tratto fra San Carlo (GR) e la frazione di Angeli Custodi.
Momentaneamente il traffico privato è stato deviato attraverso strade secondarie, mentre rimane completamente chiuso per il traffico pesante. I lavori di sgombero stanno procedendo velocemente e la riapertura della strada potrebbe avvenire già nel primo pomeriggio di giovedì. La prossima comunicazione è prevista per le ore 14.00.
