Which risk dramatically increased as the Roman road network extended into mountainous regions?

💡 Explanation

When roads traversed mountainous regions, increased loading stress promoted creep in soil/foundations because gravity acts down-slope on unstable terrain, resulting in deformation over longer periods. Therefore increased foundation creep results, rather than transport costs, speed reduction, or flooding, all requiring different geographic and material constraints.
