Which outcome increased the limitations of pre-modern stone arch bridge spans?

💡 Explanation

Increased arch bridge span required withstanding greater loads; however, bending moment capacity reduction occurred due to stone's limited tensile strength causing potential cracking because stone couldn't effectively resist tension. The bending moment, therefore, constrained larger span construction rather than compressive strength increases.
