List of bridges

Organizing principles

Common ways to organize bridge lists include:

• Structural type: arch, suspension, beam, truss, cable-stayed and movable bridges.
• Function: road, rail, pedestrian, aqueducts or utility crossings.
• Technical metrics: main span, total length, deck height, clearance, number of spans.
• Geography and history: by country, river, city, era or conservation status.

Typical fields included

Reliable entries commonly record a consistent set of fields so items can be compared and filtered. Typical fields are name and known aliases, location (city, river, country), coordinates, type and materials, opening year, designer or builder when known, principal dimensions and current status (in use, demolished, reconstructed).

Selection criteria and sources

Clear inclusion criteria prevent ambiguity: for example, whether temporary, pedestrian-only or ruined crossings are included. Primary sources include national bridge registers, engineering journals, heritage lists and government transport inventories. Secondary sources and vetted databases help fill gaps but should be cited.

Notable examples

Well-known bridges often cited in lists include the Golden Gate, Brooklyn Bridge, Tower Bridge, the Millau Viaduct and the Akashi Kaikyō crossing; these illustrate different types, historical moments and engineering milestones. Such examples are useful as reference points when explaining categories.

Records and distinctions

When ranking bridges it is important to distinguish metrics: longest main span is different from longest overall bridge length; highest deck differs from greatest clearance under the structure; oldest surviving crossing is distinct from continuously used routes. Each metric highlights different engineering or historical significance.

Uses and maintenance of lists

Researchers use lists to study transport networks, longevity and material performance. Planners and asset managers rely on inventories for maintenance and risk assessment. Digital formats and GIS allow filtering, mapping and periodic updates; crowdsourced contributions can help but require verification.

Best practices

Good lists state their scope, define terms and use consistent units. Every factual claim should cite a verifiable source. Where uncertainty exists—dates, attributions or dimensions—note the ambiguity rather than assert precise but unverified values.

Further considerations

Thematic and regional lists—by designer, by river basin or by heritage status—make large catalogs more usable. Preservation lists support conservation, while technical catalogs support research and safety assessments. Maintaining accuracy requires routine review to reflect new constructions, reconstructions and demolitions.
