Which structural problem rapidly reduces the lifespan of historic Viking-age 'rope bridges'?

💡 Explanation

Rope abrasion caused by dynamic load reduces bridge lifespan, because repeated flexing grinds the ropes; therefore integrity degrades faster from use, rather than corrosion because suitable metals don't naturally interact that severely.
