The Pont de la Liberation is a road bridge in Villeneuve-sur-Lot in the Lot-et-Garonne department ( France ) that crosses the Lot River and connects the Rue de la Fraternité with the Allée Jeanne de France and the Place de la Révolution.
history
The bridge was built between 1914 and 1919, with interruptions due to the First World War, for the Tramways du Lot-et-Garonne according to a design by Eugène Freyssinet by the company Mercier, Limousin & Cie. The bridge was called the Pont du Tramway accordingly , but was also known as the Pont Neuf .
description
The Pont de la Liberation is now a two-lane road bridge with two walkways. It is 100 m long and 10.90 m wide.
The bridge is an example of the construction method originally developed by Paul Séjourné for brick arched bridges with an overhead carriageway, which he put into practice in particular for the Adolphe Bridge in Luxembourg and which subsequently became the model for numerous concrete bridges. Two arches made of unreinforced concrete , narrow in relation to the bridge deck, form the essential part of the structure . On top of them are pillars made of brickwork, connected by round arches, which support the reinforced concrete deck.
With a span of 96.25 m, it was the world's largest arch bridge made of stone masonry or unreinforced concrete when it opened. It surpassed the Friedensbrücke in Plauen, opened in 1905 and spanning 90 m, made of quarry stone and cement mortar masonry. Only the Ponte del Risorgimento in Rome planned by François Hennebique , built from reinforced concrete and opened in 1911, was even larger with a span of 100 m.
