Roman arch – Stone Arch Bridges

Bridge Abutments

Stone arch bridges must have substantial and properly designed abutments in order to resist the enormous thrust of the arch without yielding.

Essentially a cross between Roman and segmental arches, the basket-handle arches form a unique group of intriguing arch designs.

Mutli-span stone arch bridges can be modestly challenging to build, but open up several possibilities for increasing waterway, if planned correctly.

The fill material within a stone arch bridge not only provides a roadway for vehicles, but also can strengthen the bridge… or cause trouble.

Segmental arches allow an arch bridge to achieve long spans without excessive rises, but require the ends of the arch to be firmly secured.

The Roman arch is a half-round arch shape and is a sturdy choice for small spans. Due to its rise and thrust lines a Roman arch has its limitations.
