How many rivers would an ancient Mesopotamian have to cross to get from Borsippa to Eshunna, traving the most direct route?

Between Borsippa and Eshunna, in a direct line, there were two rivers for crossing.

Explanation:

Ancient Mesopotamia was one of the major river valley civilizations, in fact, it was the first one to develop. The population was concentrated heavily along the river shores, thus all cities were built on these places, and the reason was that those were the only suitable places for people to live in larger groups in the area.

Two of the many cities in ancient Mesopotamia were Borsippa and Eshunna. They were located relatively sloe to each other. If an ancient Mesopotamian wanted to travel from one to the other and chose the most direct route, he/she would have two rivers for crossing. The first river that would need to be crossed from Borsippa to Eshunna would be the Euphrates, and after that obstacle is passed the Tigris River will need to be passed to reach the city of Eshunna.
