Cubzac-les-Ponts (; ), also referred to as Cubzac, is a commune of the Gironde department in Nouvelle-Aquitaine, a region in southwestern France.Commune de Cubzac-les-Ponts (33143), INSEE Located 20 km northeast of Bordeaux, it is a crossing point of the river Dordogne. Cubzac has three bridges, one designed by Gustave Eiffel.
During the Middle Ages, Cubzac served as a watchtower through the Four Sons of Amon castle. Different means of crossing the river in Cubzac have historically been used, from pontoon bridges and horse-powered ferries to steel and concrete bridges. Part of a vibrant wine region, Cubzac has several wine castles, including the Terrefort castle. It has developed its own sparkling wine, in what is now called the Café de Paris. The limestone quarries of Cubzac supplied for the typical white constructions found in Bordeaux and its region. Cubzac has two Monuments Historiques; the first is a painting in a church, the other is the ruins of the Four Sons of Amon castle.
Geography
Cubzac is located about 20 km northeast of Bordeaux, on the north riverbank of the Dordogne.Google Maps Several transport networks converge in Cubzac to cross the river. These include the A10 motorway, the N10 trunk road and the Bordeaux-Nantes railroad. The LGV Sud-Ouest, a high-speed railway line running between Tours and Bordeaux, is in the process of being built.Réseau ferré de France Cubzac has an elevation ranging from 1 m to 42 m, the highest points being limestone cliffs dating from the Oligocene epoch, some of which have been used as source of stone.Haute-Gironde.comDufaure 1970, p.5 In oenological terms, Cubzac is near the appellations d'origine contrôlée (AOC) côtes de Bourg and Fronsac, with its own wine castles.Sylvette Quancard 2009, p. 11
Population
Climate Cubzac's climate is oceanic, part of the Dfb group in the Köppen climate classification. Periodically, the river Dordogne causes flooding. Nowadays Cubzac is protected by a dam, but is still vulnerable to flooding during high tides and strong winds. Flooding occurred last in the 1999 Martin and 2010 Xynthia storms.prim.net The 1999 storm destroyed many trees from the Terrefort castle park.Sylvette Quancard 2009, p. 333 In 1708, a temperature extremum of -15 °C caused the river and vineyards to freeze.Sylvette Quancard 2009, p. 77
Administration Administratively, Cubzac-les-Ponts is a commune part of the Nouvelle-Aquitaine region, the Gironde département, the arrondissement of Blaye and the canton of Le Nord-Gironde. Before 2006, it was part of the arrondissement of Bordeaux. The current mayor of Cubzac is Alain Tabone, re-elected in 2020.
Economy In 2007, 890 inhabitants were professionally active, the unemployment rate for the population between 15 and 64 was 6,7% for men and 10,0% for women, and the average net taxable income was €21 593. Of the 310 jobs available in Cubzac, only 34,9% were given to its inhabitants.INSEE statistiques, pp. 5, 9 As of 1 January 2010, there were no hotels and no camping sites in Cubzac.INSEE statistiques, p. 17 Agriculture in Cubzac is mostly dedicated to vine, corn and hay. In 2000, 244 ha of Cubzac's land was farmland, representing 25% of the total 987 ha.INSEE statistiques locales, p.16
History The first traces of settlements in Cubzac date back to the Magdalenian epoch.Bardeau 1988, p. 11 Those were discovered in the late nineteenth and early twentieth centuries, with scrapers, chisels, nuclei, and harpoons found. Cut and polished axes, arrowheads, scrapers, awls and flint strikers, and a few fragments of pottery from the Neolithic epoch are plentiful in Cubzac, especially on the mound of the "Four Sons of Amon".Bardeau 1988, p. 12 A very large bronze deposit for making weapons was found from the time of the Bronze and Iron Ages. The town was mentioned in the Roman epoch as a surveillance post. Already, crossing the river Dordogne was done at Cubzac. The town has been reconverted through the centuries. The territory was occupied from the 6th century BC by a Bituriges Vivisques tribe. The village was occupied in 1250 by Simon de Montfort, 6th Earl of Leicester.Reigniez 2009 The centre of Cubzac is built on a small hill that dominates the Dordogne valley.
The village has developed from the domain of Cupitius, a wealthy landowner of the Gallo-Roman era, from which the name Cubzac derives.Cassagne 2001
Ancient crossing methods The first ferries crossing the Dordogne were flat-bottomed boats driven by oars or keelboats driven by a sail. The passage was very risky and accidents occurred, especially during high tides and storms.art-et-histoire.com From 1754, a cable ferry crossed the 550 m wide river. The cable lay above the waters and stretched obliquely to the current.Bardeau 1980, p. 25 In 1821, the cable ferry was replaced by a two-part ferry powered by a carousel of twelve horses. The horses set in motion gears which in turn powered a large paddle wheel. In good weather, the crossing time was improved to 30–45 minutes, but in bad weather the trip remained uncertain.
The decision to establish a bridge in Cubzac is taken by Napoleon Bonaparte on 30 January 1812 and 3 February 1813. The bridge was originally to be completed in 1820. However, Cubzac's first bridge was a suspension bridge for which construction works started in 1834, under Louis Philippe I.Bardeau 1988, p. 45 Works lasted four years, and public inauguration occurred on 17 August 1839 by the Duc and Duchesse of Orleans.Bardeau 1988, p.46 The bridge had cost an estimated 3 million gold francs, was 545 m long and had 5 bays. Shortly after its construction, the pillars sank about one metre. During its 30 years of existence, it withstood storms despite the large amplitude oscillations caused. However, on 2 March 1869 a large storm, causing oscillations of more than two metres, partially destroyed the bridge and rendered it useless.Bardeau 1988, p. 47 Ancient methods to cross the Dordogne where reinstated. At first, barges and steamboats were used. Then, starting from October 1870, a large steam tub was used,Bardeau 1988, p. 49 measuring 21 m by 13 m. To cover the expensive construction costs, a toll was levied for the first 27 years.Bardeau 1988, pp. 46-47
Current bridges
Eiffel bridge
When the suspension bridge fell in 1869, the idea of a new bridge was discussed at length.Carmona 2002, p. 159 The initial project dates from 1875, which proposed that the new bridge had accompanying rail tracks, and that it be built on the remaining foundations of the suspension bridge, using scaffolding. Actually, given the height of the bridge and the river's depth and current, scaffolding is almost technically impossible to implement.Carmona 2002, p. 160 In the final project from 1878, a jetting alternative was offered, despite very few companies mastering the technique at the time. The problem of fitting rail tracks, which was later abandoned, delayed the project.Carmona 2002, p. 161
In 1873, masonry works had started on the right bank.Bardeau 1988, p.49 In 1879, Gustave Eiffel, who had waited more than ten years for a positive response to his project, took in hand the large undertaking in Cubzac, which finished in 1883. The Cubzac bridge is the most important roadwork by the Eiffel company.Carmona 2002, p. 158 It necessitated 3284 tonnes of metal, measures 552 m, and is divided in eight bays. The parapet consists of iron braces rather than solid walls, alleviating the structure. The company manufacturing the iron pieces later provided those used for the Eiffel Tower.Carmona 2002, p. 162
As the Allies landed in Normandy, the German troupes, in their escape, partially destroyed the Eiffel bridge using explosives.Bardeau 1988, pp. 52-53 Starting from 21 August 1944, all traffic on the bridge was restricted for the retirement of the German troupes.Bardeau 1988, p. 53 On 28 August 1944, as the last soldiers passed, German engineers arrived in bicycles and fitted explosives which detonated at 9:20pm. Three of the eight bays had fallen in the waters and the North abutment was seriously damaged. The delicate repair works where operated by the company Anciens Ets Eiffel with the help of the Entreprise Générale Industrielle du Sud-Ouest, which coincidentally was directed by Jacques Eiffel, the grandson of Gustave Eiffel.Bardeau 1988, p. 55 For this reason, the bridge is sometimes called "the twice Eiffel bridge".Carmona 2002, p. 168
The bridge is now part of the Route nationale 10 which runs between Hendaye and Paris.Centre d'Études Techniques de l'Équipement, p.1 Both viaducts to the bridge date from 1839 and each measures approximately 250 m. Over time, large settlements occurred, causing serious disturbances in the masonry and requiring the replacement of many vaults in 1880, 1903 and 1934.
Railway bridge
The rail bridge was constructed by Lebrun, Dayde and Pile by the compagnie Deyle et Pillet.Bardeau 1988, p.52 Its style resembles that of the adjacent Eiffel bridge. It was commissioned by the Chemins de Fer de l'État for the Chartres-Bordeaux line, and the construction lasted from 1884 to 1885. Inaugurated in 1886, it is 561,60 m long above the Dordogne are divided in eight bays. The rails are 21.80 m above the highest waters. The bridge is made of iron pillars fitted in braces. Despite being younger than the Eiffel bridge, the construction necessitated more funds and effort. The constructions hidden under water and earth make up the bulk of the value and volume of materials used. Foundations only total to 57,800 cubic meters. Even though less damaged than the Eiffel bridge, it also sustained damage from German bombing on the same day. The reconstruction works ended on 15 June 1946, having taken less than two years to complete.
Motorway bridge In 1957 it was decided to study the implementation of a bridge to relieve the old Eiffel bridge which allowed only one lane per direction, and reduce traffic jams. From 1957 to 1963 various solutions where studies. In 1971 the construction works were tendered and given to the company Campenon-Bernard-Europe. The works should have lasted only two years but were completed in 1974. The new motorway bridge made of reinforced concrete, having relieved the traffic jams, was celebrated on radio, and by the song "Ne partez pas en vacances, ne partez pas!" (Do not, do not go on holiday!) by Pierre Perret.Bardeau 1980, p. 33 In 2000, the bridge was doubled to 2x3 lanes.Meynard

Saint-Julien church
The Saint-Julien church is named after Julian the Hospitaller, patron of Cubzac. Julian is a legendary saint destined to kill his parents, and informed about his destiny by a stag. He fled to escape his fate, but the prophecy realized nonetheless, and he became a hermit, helping people cross a river. One day, the Christ arrived to announce his pardon.catholic-saints.info From the Middle Ages to the French Revolution, the town would have been called Saint-Julien-de-Cubzac.Bardeau 1988, p.73 The church is made of limestone and underwent important modifications in the 19th century, when in particular the steeple was rebuilt. The façade, however, still contains Roman remains.Christophe Meynard The church holds an 18th-century painting of the Baptism of Christ, classified Monument historique in 1913. The church is surrounded by a cemetery which was excavated in August 1978 by archaeologists under the direction of Richard Boudet.Bardeau 1988, p.71 Coins dating from the time of Francis I, Henry III, Henry IV, Louis XIII, Napoleon III, and Victor Emmanuel II were uncovered. A gold Merovingian signet ring bearing the Christian symbol Ichthys was also discovered under many potsherds.
