The transit connections between Calcutta and Dhaka are very poor. Each city has well over 10 million people, and the two cities are less than 200km apart. But the road and rail connections are very poor. Obviously history plays a big role here, but will the situation ever be fixed? There could be a lot more commerce and transit if these two megacities had a high-quality motorway and rail line between them, including a bridge across the Padma River.
