Why these 20
Total length as recorded in Wikidata, converted to metres. Long causeways and elevated roads over lakes, bays and wetland lead the world list; each country page shows its own long crossings. Some record rail viaducts have no length in Wikidata yet, so they are missing until editors add it.
Built from the regions below: the best 20 of all of them.
