| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Arches and Domes (arches_domes) | required | 86% | review | The scoped bridge form is defined by masonry arches, so arch construction is a direct structural prerequisite. |
|
| Roads (roads) | enabling | 72% | review | Pons Fabricius connected urban road movement across the Tiber Island, so road and urban-circulation needs enabled the bridge class. |
|
| Concrete (concrete) | common_dependency | 50% | weak_inference | Concrete is relevant to some later Roman bridge engineering, but the Pons Fabricius anchor is a stone masonry bridge; this is contextual, not required. |
