a long, elevated structure that carries a railway or road across a valley or river, typically held up by a series of arches

Examples

1. Fanciful viaducts compliment the natural landscape.

2. And that meant long viaducts over river valleys.

3. What's more, Chinese high-speed rail lines include a lot of viaducts.

4. So a Victorian railway viaduct, Brunel's extraordinarily elegant spare and an amazingly flat bridge across the Thames at Maidenhead has carried the high speed trains for years and years.
