List of longest masonry arch bridge spans
- List of longest masonry arch bridge spans
The masonry arch bridges of stone or brick are the most genuine of arch bridges, some lasting a thousand years. Because they are made of worked stone, there is a slight chance they might even stand without mortar, like the Pont du Gard aqueduct. Arches with a core of reinforced concrete covered by facade stone for decoration are not to be included in this list, the load bearing part of the arch should be cut stone or brick. The Syratal Viaduct is a special case as the arch is made of "un"reinforced concrete and would not stand without mortar. The Maidenhead Railway Bridge may have the two longest arches made of bricks, convert|39|m|ft|0.
This list contains the longest masonry arch spans ever built exceeding convert|50|m|ft|0. Only eleven bridges with spans this large were built before the 20th century. Building new masonry arch bridges today is a solely Chinese business.
