Given the same construction materials (originally stone) an arch is tremendously stronger than a post and lintel. You can pile much more weight on an arch without causing it to collapse, as compared to the post and lintel; the lintels break much more easily.
The arch's weight is transfered over instead of straight across.
The Roman arch improved on the post and lintel system by distributing weight more effectively, allowing for larger and more stable structures. Unlike the rigid horizontal beams of the post and lintel design, the arch utilizes a curved structure that redirects forces downward and outward, reducing the risk of collapse. This innovation enabled Romans to build monumental architecture, such as aqueducts and bridges, with greater height and span than Greek constructions. As a result, the arch became a fundamental element in Roman engineering and architectural design.
