KnowraViaductViaductA long bridge or series of connected spans carries a road or railway across a valley, gorge, or other low ground.BriefConnectBridge: A structure that carries a path, road, railway, or utility over an obstacle. A viaduct is a bridge form distinguished by its length and repeated spans.Arch bridge: A bridge whose curved structure carries loads mainly through compression toward its supports. Masonry viaducts often use repeated arches to transfer deck loads into piers.Railway: A transport system that moves trains along fixed tracks. Viaducts let railway lines maintain manageable gradients across valleys.Millau Viaduct: A cable-stayed road viaduct spanning the Tarn valley in southern France. Its tall piers and long deck demonstrate modern valley-crossing design.Bridge span: The section of a bridge between two adjacent supports. Repeated spans let a viaduct cross broad low ground.Beam bridge: A bridge in which horizontal beams span between supports and resist loads through bending. Beam construction offers a different way to bridge each gap between viaduct supports.Highway: A major public road designed to carry substantial motor traffic. Road viaducts keep traffic moving above low ground and intersecting routes.Glenfinnan Viaduct: A curved concrete railway viaduct in the Scottish Highlands, completed in 1901. Its repeated concrete arches carry the railway across a broad valley.Pier: A vertical support that transfers loads from a bridge deck to its foundations. Piers commonly support the successive spans of a viaduct.Cable-stayed bridge: A bridge whose deck is supported directly by inclined cables connected to towers. Cable stays can replace repeated piers where long clear spans are needed.Show all 24Linked from 8 pagesBridge pierBroader topic: Its repeated spans commonly rest on a line of piers.Railway bridgeRelated: Railways use viaducts to maintain a steady gradient across broad terrain.Trestle bridgeNarrower topic: A trestle bridge can form a viaduct from repeated short supports.Danyang–Kunshan Grand BridgeNarrower topic: The bridge is predominantly a viaduct, with repeated elevated spans across eastern China's landscape.Vasco da Gama BridgeNarrower topic: Long viaduct sections extend the route beyond the central cable-stayed crossing.Show all 8
