Which effect limited long section road construction in pre-Roman Europe before 300 BC?

💡 Explanation

Before extensive Roman road infrastructure, inadequate drainage techniques in pre-Roman Europe caused rapid roadbed saturation and collapse especially when sustained across long runs Because uncontrolled water flow accelerated erosion damages, roads constructed with simple materials became easily damaged Therefore, inadequate drainage accelerates erosion, rather than causing problems with supply, stability, or loads alone. These came at later times.
