Which outcome occurs when the construction of substantial Roman roads crossed unstable alluvial plains?

💡 Explanation

Increased road subsidence becomes a risk, because soil compaction causes differential settling under the road’s weight, and the mechanism is consolidation settlement. Therefore, the road surface deforms, rather than maintaining its flat state or leading to military/economic effects.
