Which outcome occurred due to Roman roads intersecting marshes?

💡 Explanation

Road collapse became frequent because saturation increased pore water pressure in poorly compacted roadbeds, exceeding the material's shear strength, leading to deformation via the mechanism of soil liquefaction; therefore, constant repairs became vital, rather than drainage adjustments alone.
