viaduct (plural viaducts)
- A bridge with several spans that carries road or rail traffic over a valley or other obstacles.
1918, W. B. Maxwell, chapter 7, The Mirror and the Lamp:
- […] St. Bede's at this period of its history was perhaps the poorest and most miserable parish in the East End of London. Close-packed, crushed by the buttressed height of the railway viaduct, rendered airless by huge walls of factories, it at once banished lively interest from a stranger's mind and left only a dull oppression of the spirit.
