Back when the Pont d’Aquitaine was still the ‘Nouveau Pont de Bordeaux’
A few weeks ago, I picked up a pamphlet that was produced around 1960 and which provided a full overview of the ambitious project to build a suspension bridge over the Garonne between the Bacalan quarter of Bordeaux and Lormont. The bridge, referred to at the time as the “Nouveau Pont de Bordeaux”, went on to be inaugurated in 1967 and is now a familiar local landmark: the Pont d’Aquitaine.
Of course, the bridge was already the subject of a full Invisible Bordeaux report a few years ago, along with a video clip taking in the view from the cycle paths! But what more would I learn from this unusual fold-out pamphlet, credited to Ponts et Chaussées de la Gironde and comprising an impressive amount of originally handwritten data and information, along with a series of pre-computer age technical illustrations and cartography? And how did the technical drawings and maps compare with the finished product, 50 years on from completion?
For a start, the financial structure of the project is detailed. The bridge itself and the left-bank viaduct were set to cost 97 million “nouveaux francs” (France had just switched systems) which, when accounting for inflation (using calculation methods developed by national statistics institute Insee), represents around 154 million euros in today’s money. The French State was delivering on two-thirds of the budget, while the Gironde département and the city of Bordeaux split the remainder in two. Throw in the right-bank connecting road and the bridge amounted to a 100-million-franc project.
The document also lists the quantities of the main raw materials that would be needed to build the bridge. To highlight but a few, these included 132,000 cubic metres of ordinary and reinforced concrete, 8,500 tons of steel for the reinforced concrete, 1,900 tons of cables for the support and suspension system and 4,350 tons of rolled steel for the bridge's main framework. In its initial configuration, the surface area of the bridge and viaduct amounted to 25,000 square metres.

This is how it translated into reality: note the pedestrians over to the right! Picture taken soon after the bridge opened by blog reader Jean-Claude Déranlot. Thanks Jean-Claude! |
The cycle path (which lies just behind the red barriers) now loops around the exterior of the pylons. |
Leafing through the technical drawings, it does look as if the design of the top of the pylons must have been revised ahead of construction, with slightly slimmer horizontal sections connecting the vertical pillars on the finished product.
Reassuringly, the engineers’ calculations regarding the viaduct’s 4.66% gradient and the curvature of the suspension system translated seamlessly into reality.
The deck now spills over the edge of the structure (where the cycle path passes) when it must have been perfectly aligned in the bridge's original configuration. |
The pamphlet also provides a cross-section view of the bridge's original suspension cables, each of which was made up of 37 individual cables that were 78.5 millimetres in diameter. Elsewhere in the document, it is explained that those individual cables comprised 208 4.7-millimetre steel wires. In all, each 48cm x 55cm suspension cable weighed in at 1.15 ton per metre. During the 21st-century renovation, all that changed was the diameter of the individual cables (72.6mm) and associated steel wires (127 4.1 mm wires), along with the overall size of the suspension cables (45cm x 51cm).

The way it was planned in the 1960s and the way it is now (via Googlemaps): the humble roundabout has become a spaghetti junction. |

I was recently approached for an interview by the Bordeaux tourist office ahead of the launch of their new webzine, Un Air de Bordeau...
Introducing 'Un Air de Bordeaux', taking locals out of their comfort zone!
A few weeks ago, Invisible Bordeaux teamed up with la Mémoire de Bordeaux Métropole to head inside one of the city’s most famous la...
Three things you (possibly) didn’t know about Bordeaux’s Pont de Pierre
The resulting video interview was subsequently published by Mémoire de Bordeaux Métropole on social media, and here is what Laurent taught us about the inner secrets of the emblematic bridge.
1. The Pont de Pierre is hollow!
Inside view of the Pont de Pierre! |
"In August 1944, the Spanish guerilla Pablo Sanchez saved the bridge simply by walking through these tunnels. The Germans had positioned explosives inside each pillar in order to blow up the bridge. Pablo Sanchez defused all the explosives; sadly he was shot when exiting the bridge on the left bank. There is a plaque in his honour on the waterfront and his name was recently given to a road in the new dockside developments."
2. Instruments permanently monitor the bridge
Laurent Rascouailles: "There are instruments inside each pillar and in its abutments, to monitor all the bridge's movements. There is a displacement sensor in each abutment and each pillar, to keep track of how much the pillars are sinking into the ground. Then there is an inclinometer to know which way the pillars are leaning in relation to the river, whether it's upstream or downstream. And a mechanical level enables us to monitor the transversal and longitudinal rotations of its supports."
3. Steps that now lead nowhere... used to provide underground access to toll collection offices!
Stairway to nowhere. |
"The toll system stopped in August 1861 when the State acquired the bridge with the support of the city of Bordeaux and the département. One of the conditions was to make the bridge free to cross, so that Bordeaux could expand on the right bank, towards La Bastide. The toll booths were then used to collect octroi duty tax from 1861 until its abolition in 1927, and the buildings were finally demolished in 1954 when the bridge was widened, from a width of around 15 metres to 19 metres. At ground level, the pavements you walk on these days were added when that extension took place. The duty collection buildings had become a hindrance for movement and, therefore, hindered access to the bridge."

On almost every street in Bordeaux there are bricked-up windows that add a sense of mystery to the associated buildings. What can the sto...
The phantom windows of Bordeaux
Rue Croix-de-Seguey. |
While this is the primary reason for so many windows having disappeared into thin air, there can be others: in some cases, owners may have added window-shaped designs as a "trompe l’œil" feature to add coherency and/or symmetry to an exterior, or to visually break up an otherwise monotonous empty space. Finally, some may have simply chosen to block off their windows for structural reasons or because they were having to deal with too much sunlight!
In many cases, phantom windows of the like are to be found on buildings located on street corners; having two walls to play with obviously provided owners with more leeway, such as pictured below on rue Commandant-Arnould (also featured in the lead photo) and rue Barennes. In both cases, the brickwork and smooth lines suggest these may be trompe l'œil features.
The phenomenon is by no means restricted to tall buildings in the city centre. Bourgeois townhouses in residential neighbourhoods are also short of a few windows, as can be seen here on rue Rochambeau, rue des Deux-Ormeaux and cours Marc-Nouaux. In each case, anything between four and seven windows (and even a large arched doorway) have either disappeared from view, or else were never there to begin with!
Smaller homes have also played the phantom window game, such as here on rue Henri-Matisse (where no less than three of the six first-floor windows have been cancelled out) and rue de l'Arsenal.
Meanwhile, at the other end of the Bordeaux class system spectrum, Château Pape-Clément, out in Pessac, also boasts its own mystery windows!
In some cases, bricked-up windows, whatever their reason for being, have been cultivated as bona fide trompe l’œils. That is the case for instance on rue Mandron, where the windows in the row over to the left of the picture below are full-on optical illusions, the non-windows convincingly painted to look like genuine ones.
But perhaps my favourite use of a ghost window, pictured below, is to be found on rue d'Arcachon. A board which has been affixed to the window features, appropriately enough, an interpretation of Salvador Dalí's "Figura en una finestra" (Figure at the Window). The picture is signed/credited to "B. Bodin d'après Dalí".
A few days ago I attended a concert by the Australian folk and indie pop duo Angus & Julia Stone at l'Espace Médoquine in Talen...
Inside l'Espace Médoquine for the last time
The multi-purpose venue, best known as a concert hall but also used by local associations and businesses for meetings, conferences and miscellaneous events, was built in the late 1980s to the designs of the Gujan-Mestras-based architect Bernard Vayssière. French singer Yves Duteil was the first headline artist to perform there on March 4th 1989.
The venue could be configured according to the event at hand, catering for attendances of anything between 250 and 1,000 if seated, and up to 3,000 standing. The standing configuration is the one with which I am most familiar as a concert-goer; during my first stay in Bordeaux in the 1990s I saw many personal favourites there including Joe Jackson, Lloyd Cole, Stephen Duffy and Tears For Fears. In more recent years, my occasional Médoquine concert outings have included the electronic rock outfit Archive and alternative pop band Metronomy.

But the local music history books will probably associate the venue with more notable appearances by the likes of the Michael Hutchence-led INXS in June 1993. They had just made the uncomfortable move of downsizing from stadium gigs to more intimate mid-sized venues, and la Médoquine fitted the bill nicely. And, in June 1997, one David Bowie brought his Earthling tour to Talence; this was the only time Bowie was to perform in the area.
Beyond my personal concert-going memories of the venue, my day-job duties in the Communications team at Thales have enabled me to view la Médoquine in a whole new light, spending full days there working on the organisation of new year all-staff meetings. This has meant I have enjoyed the enviable privilege of sitting behind a big mixing desk feeling like I’m important or, with the whole venue to myself pre-event, wandering about on stage secretly pretending I’m Joe Jackson or David Bowie.
On stage: take the seats away and you more or less have a Bowie-eye view of la Médoquine. |

La Médoquine's futuristic design will soon be a thing of the past... |
Elsewhere on the outskirts of Bordeaux, Théatre du Casino Barrière and suburban venues like Théâtre des Quatre Saisons in Gradignan have also drawn potential artists and clients away from la Médoquine. Finally, over in Floirac, the cutting-edge Bordeaux Metropole Arena will shortly be opening for business, with a capacity ranging from 2,500 to 11,300, simultaneously overshadowing la Médoquine and replacing the acoustically-challenged Patinoire Mériadeck in central Bordeaux. Meanwhile, Cenon is also considering building an additional 2,500-capacity venue alongside the Rocher de Palmer!
