Prendono avvio oggi, mercoledì, con il primo brillamento,i lavori di scavo del tunnel destinato a collegare Vinadi e Samnaun. La messa in esercizio della galleria, come precisato in una nota diffusa dal canton Grigioni, è in programma per l'estate del 2024.
La strada che allaccia le due località retiche, come si sottolinea nel comunicato, è un elemento importante della rete cantonale e rappresenta il solo collegamento stradale su suolo elvetico. Ma nell'intera zona legata al progetto è anche molto stretta, esposta a molti pericoli naturali e deve a più riprese restare chiusa in inverno a seguito di valanghe.
La nuova struttura consentirà di migliorare la situazione. Con due corsie, una lunghezza di 630 metri, un'altezza pari a 4 metri e mezzo e una larghezza di carreggiata di quasi 6 metri, il tunnel consentirà di ottimizzare i flussi del traffico, rafforzando in misura sensibile la sicurezza degli utenti della strada.
