Lets talk a little bit about the industries and why some regions are important for the world of transport.
I will start from south.
In Mostar there is a aluminum factory. As you can see on photos, this is a very big factory. (In some of my previous posts I have posted some important roads in Bosnia and Herzegovina)

As you can see there is a road M17 which on north goes to Sarajevo and on south to the border crossing with Croatia.
In Sarajevo there are many factories, for example factory of cigarettes and so on... but I dont have some good photos to show you.
In Tuzla there are factories of Salt (Tuzla is recognized in world as a "Salt City"), Cement factory, Beer factory, there are also the thermal power plants and so on...
Beer Factory is located in the center of the city Tuzla.

This route uses trucks (if they are entering from east in Tuzla) to load their cargo in the Beer factory but I know that people from SCS know that. This road M4 goes on east to the city of Bijeljina. Bijeljina is the agricultural area.

On the second turn there you can see this building which is finished now and looks like this:
The factory of Salt is located here:
