Top 10: World’s longest bridges
A structure spanning the English Channel wouldn’t come close to Earth’s 10 lengthiest bridges.
Many have floated the idea of a bridge between England and mainland Europe. This Channel-spanning bridge would need to be 35km long, a distance that would make it the lengthiest bridge in Europe – well beyond Portugal’s 17km Vasco da Gama Bridge. However, such a construction still wouldn’t break into the world’s top 10 longest.
