What makes such an indication of disbelief that Old AT road is a black topped road? The road indeed looks like a kutcha mucky road. In fact the road is a mucky one with mucks, made of mud of silt being left behind by trucks every now and then, covering the entire width of the road at the stretch between Mazirgaon and Garal. A number of trucks carry silt from the bed of the Brahmaputra via this road, and while carrying the muddy silt the trucks leave behind bulk of the material, and muck the road up.
