Which risk increased during Roman road construction due to timber bridging soft terrain during wet seasons?

💡 Explanation

When timber bridging crossed weak ground, soil consolidation occurred because the timber’s weight compressed the saturated soil. Therefore, subsidence resulted, rather than corrosion, erosion, or thermal deformation requiring different environmental conditions or material properties.
