Great St Bernard Tunnel Closure Extended After Avalanche Damage

The Great St Bernard Tunnel, a crucial transportation link between Switzerland and Italy, remains indefinitely closed following significant avalanche damage. The closure, triggered by heavy snowfall in canton Valais last week, has completely halted traffic through this vital north-south Alpine route. The tunnel management company confirmed on Tuesday that no reopening date has been established, leaving travelers and freight operators seeking alternative routes.

The avalanche near the Toules tunnel on the Swiss side has caused extensive damage to approximately 300 meters of tunnel infrastructure. Boulders and trees swept down by the avalanche have compromised the tunnel's structural integrity, necessitating thorough safety assessments and repairs. The simultaneous closure of both the tunnel and the mountain pass has effectively cut off the route to Italy via Bourg-Saint-Pierre, significantly impacting cross-border movement.

The impact extends beyond the tunnel closure, affecting the broader Valais region. Approximately fifteen cantonal roads remain closed across Upper and Central Valais, though alternative routes have been established for most affected areas. Notable closures include the sections between Stalden and Embd, and between Vercorin and Itravers due to landslides. The Ayer – Zinal road has been closed due to ongoing avalanche risks. Local authorities continue to implement safety measures, including restricted access to various pedestrian areas in Sion and Sierre.

The indefinite closure of this key Alpine route has significant implications for both commercial and personal travel between Switzerland and Italy. The Great St Bernard Tunnel typically serves as a crucial artery for international freight transport and tourism. Local businesses in the affected regions are experiencing disruptions, while logistics companies are forced to utilize longer alternative routes, increasing transportation costs and delivery times. Swiss authorities are working closely with their Italian counterparts to manage the situation and provide updates to affected stakeholders.
