Though ribbed arches are usually associated with concrete, it is possible to build a stone arch bridge out of separate parallel arch ribs, thereby saving centering.

Why Stone Arch Bridges?
There are several advantages inherent to the stone arch bridge. Aesthetics, a valuable use of local resources and longevity all are factors in favor of stone arch bridges.
Lighter Stone Bridges
Stone bridges are inherently quite heavy. This can sometimes cause foundational or arch problems, prompting designers to come up with ingenious solutions.
Choosing Quality Rock
Even with a given type of stone, there can be considerable variation. It helps to recognize some basic signs of poor stone to ensure long-term durability.

Different Classes of Masonry Part 3: Rubble Masonry
While rubble masonry is considered the lowest class of stone work, it still can be used to make enduring structures and is peculiarly suited to DIY projects.
Different Classes of Masonry Part 2: Squared-stone
Squared-stone masonry is a method of building masonry to achieve a highly durable structure without resorting to the difficulty and labor required for ashlar.
Different Classes of Masonry Part 1: Ashlar
Ashlar is the highest grade of stone work, and features extensive stone cutting and tight fitting joints. Ashlar work is difficult, but very durable due to the precision required.
Building Better Masonry
Masonry is rewarding undertaking. There is no “magic” behind building enduring structures, rather, stone masonry is easily learned with practice.
Building an arch that is tapered by making the haunches thicker than the crown is a clever way to make a strong bridge without increasing the “hump.”
