Which construction risk increased when Roman road builders used improperly seasoned timber for bridge supports?

💡 Explanation

Using wet timber leads to wood shrinkage by desiccation stress, weakening joinery, which decreases structural integrity. This causes premature collapse because the timber warps and fails, rather than maintaining its intended stiffness under compressive loads, thus decreasing the lifespan.
