Heavy rain damages Mirik causeway, disrupting heavy vehicle traffic
Heavy rain made the Balason river rise quickly near Mirik.
The fast-moving water washed away a temporary road crossing called a causeway.
This means large trucks cannot travel directly between Siliguri and Mirik.
A nearby Bailey bridge is still open for small vehicles and motorcycles.
Large vehicles must take a longer route through Sukhiapokhri, Ghoom and Kurseong.
Another temporary crossing over the Rangbhang river was also damaged.
A landslide cut off a road between Sirikhola and Rammam.
Officials say more rain and storms may continue across north Bengal and Sikkim.
Heavy rain washed away the Dudhia causeway over the Balason river early Friday.
The damage disrupted direct heavy-vehicle movement between Siliguri and Mirik.
A 58-metre Bailey bridge remains open to light vehicles and two-wheelers.
Heavy vehicles must use routes through Sukhiapokhri, Ghoom and Kurseong.
Landslides and road damage were also reported in Darjeeling district and south Sikkim.
