The Big Trunk Route runs through:

The Mediterranean The North Atlantic Ocean The South Atlantic Ocean North Pacific Ocean

The North Atlantic Ocean

The Northern Atlantic Sea Route This links North-eastern U.S.A. and North western Europe, the two industrially developed regions of the world. The foreign trade over this route is greater than that of the rest of the world combined. One fourth of the world’s foreign trade moves on this route. It is, therefore, the busiest in the world and otherwise, called the Big Trunk Route. Both the coasts have highly advanced ports and harbour facilities.
