Ships, boats, ferries, planks are an integral part of the Brahmaputra. There are only three bridges on the river, whose entire length spans 2900 kms !
The one at Sariaghat, near Guwahati, Assam has a rail bridge. Currently this is the only railway link to the all north eastern states of India. A fourth bridge is under construction at Dibrugarh and will be a road cum rail.
Thousands of people still cross the river daily to go to work, school, shops or to get medical aid. Hence it is a common site to see ferries filled with people, motorbikes, cycles, live stock, daily shopping that varies from vegetables, large Godrej cupboards to vehicles of all kinds.
The Kaziranga sanctuary also relies on boats donated by the International fund for animal welfare and wildlife trust of India to rescue animals during floods and move them to safety.
I have put together some visuals that tell a wonderful story.
