What Is On Lagos/ibadan Expressway:

In economics,I learnt that one of the factors that affects location of an industry is nearness to raw materials.
This principle seems to have lost its important role in the thinking of those who have turned the Lagos/Ibadan expressway to religious industrial estate.

Did u see this factor playing itself high here?

If no,fellow Nairalanders,please tell me what are the likely factors that influence their influx into this area.
