A chain bridge is a historic form of suspension bridge for which chains or eyebars were used instead of wire ropes to carry the bridge deck. A famous example is the Széchenyi Chain Bridge in Budapest.

Construction types are, as for other suspension bridges, a stressed ribbon bridge, a true suspension bridge, and special forms, such as the Tower Bridge and the Albert Bridge, London.

Chain bridges were the first bridges able to cross wider spans than the previous wooden and stone bridges, combined with shorter building times and at lower costs.[1]

History

[edit]

The first chain bridge in Europe was the Winch Bridge, built around 1741 across the Tees in North-eastern England.[2] It served mainly miners entering the nearby mine. It collapsed in 1802, and was replaced in 1830 by a suspension bridge with suspension chains.

A chain bridge was built in the 1780s and 1790s in the Wörlitzer Park which crossed a canal between artificial rocks. The light construction was intended to move, to create sensual sensations[clarification needed] for the visitors of the park.[3][4] The Steinfurter Bagno park had a chain bridge from 1794.

In 1820, Samuel Brown opened the Union Bridge over the River Tweed on the Scottish-English border, which was the first suspension bridge in Europe suitable for carts. It is the oldest such bridge still used for traffic.

Claude Navier published the first fundamental paper about suspension bridges in 1823.[5]

The first chain bridge on the European continent was opened in 1824, the Kettensteg in Nuremberg. A little later, the Rotundenbrücke [de] crossing the Donaukanal in Vienna was opened for pedestrians and carriages. To celebrate this event the Chain Bridge Waltz was written by Johann Strauss.

In 1849, the Széchenyi Chain Bridge over the Danube in Budapest was opened, designed by William Tierney Clark, spanning 200 m. The Empress Elisabeth Bridge over the Elbe at Tetschen (today: Děčín) was completed in 1855, and the same year the Nicholas Chain Bridge in Kyiv, which spanned the Dnieper in four segments of 143 m.

The Tower Bridge in London was opened in 1884, a unique combination of suspension bridge and drawbridge, and the Elisabeth Bridge in Budapest was opened in 1903, marking the peak of chain bridge building.

Later bridges of the type included the Kaiserbrücke in Breslau (today: Grunwaldbrücke in Wrocław) of 1910, and the Deutzer Hängebrücke, which opened in 1915. The Three Sisters were three similar bridges in Pittsburgh, Pennsylvania, built from 1924 to 1928 over the Allegheny River. The Hercilio Luz Bridge in Brazil 1926 had the longest span of all chain bridges at 339,5 m. A similar bridge was built two years later, the Silver Bridge over the Ohio River. It collapsed in 1967.[6] The last large chain bridges were the Reichsbrücke in Vienna (1937) and the Krymsky Bridge in Moscow (1938).
