Bridges presentation
Later, the use of artificial cement combined with more sophisticated understanding of the
mathematical principles of arch theory resulted in renewed interest in stone and masonry arch
bridges in Europe. Beginning in the mid-19th century, masonry railroad viaducts were an important
civil engineering technology for continental Europe. The most impressive were the 1969ft (600m)
long Chaumont Viaduct (1857) and the 240ft (73m) high Sainte-Brieuc (Barentin) Viaduct (1860),
both in France, and the Goltzschtal Viaduct in Germany, which used 26 million units of brick.
The French engineer, Paul Séjourne, expressed the most elegant modern restatement of the
principles of this most ancient material in his masterpiece bridges of stone, the 279ft (85m) span
Pont Adolphe in Luxembourg (1903) and the bridge at Plauen, Germany (1905), which was the
longest ever achieved in stone masonry, with a span of 295ft (90m).
