The southernmost autoroute in France is this one. It's not officially called "autoroute", but it's an autoroute in all but name. Even the signs are blue as you can see in the video, just like on autoroutes. It's located by 22°13 South, the same latitude as Rio de Janeiro. I let you guess where it is.

The videos show essentially the most urban parts of the motorway. Further from the city it becomes more like a French autoroute through the countryside, but I couldn't find videos of these parts.

The autoroute starts at 0:23 in the video:


On a busy day in the most urban stretches of the motorway:


The "péage" (toll gate) at the end of the motoroway (when coming from the countryside to the city):

Route des Tamarins in la Réunion is not officially an autoroute either.

I had posted this video in the thread "France, one bridge a day", I think it is worth to be shared here:

By the way the construction of the "nouvelle route du littoral", between Saint-Denis and La Possession, is due to start in mid-2013.

I see no 'chopsticks', therefore not an autoroute!

or even a 'happy car' sign. Though looking on the map, it will have these given it is classed as voie express.

And your videos are of the wrong road as the southernmost voie express(which is not the same as autoroute, even if the signs are incorrectly blue) in New Caledonia is a tiny little one in Magenta.

That's currently the most impressive motorway project in the world outside of China probably. I didn't know it was starting this year already. How much is it costing?

The name appears in one of the videos I posted. 18.5 km are under motorway regulations if WikiSara is correct, although the speed limit is 110 km/h. The motorway then continues as an expressway for a further 6.2 km in the more urbanized parts of Nouméa, with a speed limit of 70 km/h since July 2011 (before July 2011, the speed limit was 80 km/h).

The motorway should be extended to Tontouta Airport in the future, so that should be a further 18 km of motorway (at 110 km/h I suppose). Initially they planned to bypass the Col de la Pirogue ("Pirogue Pass"), which is at an altitude of 172 meters above sea-level, by deviating the future motorway towards the south (i.e. towards the coast), but now apparently they plan to go in a straighter way under the pass via a tunnel, the first road tunnel in New Caledonia (and a 4-lane tunnel at that!). The tunnel would cost between 10 and 15 billion Pacific francs (90 to 125 million euros), depending if they chose the option of a 1.1 km tunnel plus a 700 meter viaduct (125 million euros) or the option of a 550 meter tunnel (90 million euros), but with the 2nd option the motorway would be 1.6 km longer than with the 1st one (the 1st option is straighter).

Here are the two options. "Tracé court" (short route), with the long tunnel, would cost 125 million euros. "Tracé long" (long route), with the shorter tunnel, would cost 90 millions euros.

According to the article below, the results of further studies will be released in April, then it's up to the Congress of New Caledonia to decide. Digging the tunnel could start in 2015. The current 2-lane road on both sides of the mountain (from the bottom of the mountain to Tontouta Airport to the north, and from the bottom of the mountain to the current motorway to the south) will be simply enlarged to four lanes (2x2) because it goes through flat land and is not surrounded by suburbanization yet, but they need to hurry because suburbanization north of Nouméa is progressing rapidly.

Un tunnel pour passer le col de la Pirogue

Les Nouvelles calédoniennes
15 mars 2013

Passer le col de la Pirogue sans virages et en 2x2 voies ? Le projet, étudié par le gouvernement, prévoit la construction d’un tunnel et pourrait coûter entre 10 et 15 milliards. Avec en ligne de mire un prolongement de la 2x2 voies jusqu’à Tontouta.


Les premières estimations financières seront affinées dans l’avant-projet sommaire, attendu en avril. Mais il est certain qu’un tel tronçon avec tunnel coûtera jusqu’à cinq fois plus cher qu’une 2x2 voies classique en rase campagne.

Avec son tracé sinueux, le Col de la Pirogue est le point noir de la RT1 entre Nouméa et Tontouta. Dix-huit accidents corporels, dont six mortels, s’y sont produits ces cinq dernières années, selon la DITTT (*). Pas moins de seize sorties de riverains sont recensées sur les quelques kilomètres qui séparent Port-Laguerre et La Tamoa. Creusée sur le coteau, la route subit régulièrement des glissements de terrain, comme lors du passage de Vania il y a deux ans. Au-delà de la sécurisation de ce tronçon, c’est aussi et d’abord la nécessité de desservir correctement l’aéroport depuis Nouméa qui motive la recherche d’une solution par les élus du pays, avec en ligne de mire, le rêve d’une 2x2 voies sur l’ensemble du parcours. « Aujourd’hui, ce n’est pas le trafic, mais bien le temps de parcours qui justifie un passage à 2x2 voies », relève Pascal Jolly, directeur de la DITTT. Un rêve qui a un coût. Le projet de contournement du col bien plus au sud côté mer, étudié en 2006 par la province Sud, avait été abandonné dès 2009 devant les difficultés budgétaires de la collectivité. Cette fois, c’est le gouvernement qui a repris le dossier, avec la ferme intention d’aboutir, sous la houlette de Gilbert Tyuienon, vice-président en charge des infrastructures et des transports.

Contournement. Une étude de faisabilité, achevée mi-2012 par la DITTT, a permis de sélectionner deux tracés parmi une dizaine d’hypothèses. Plus longs, les itinéraires de contournement, passant plus au sud, en pied de col, ont été éliminés. Avec les deux scénarios retenus, il ne s’agirait plus de contourner le col, mais bien de le franchir de façon plus directe, d’où la nécessité de construire un tunnel qui, s’il voit le jour, serait le premier sur le Caillou. Le premier tracé, plus court, prévoit une route à 2x2 voies de 3,6 km, avec un tunnel de 1,1 km, ainsi qu’un pont de 700 mètres, d’où une première estimation grossière à 15 milliards de francs. Un peu plus long (5,3 km), mais aussi a priori moins cher (10,7 milliards) le second tracé ne nécessiterait qu’un tunnel de 550 mètres et plusieurs petits ouvrages hydrauliques.

Pour préciser les coûts et la faisabilité de l’opération, un avant-projet sommaire (APS) a été commandé au bureau d’études Infratech, qui rendra ses conclusions courant avril. Charge à lui de rentrer notamment dans le détail des études géotechniques : en fonction du type de roche (sa dureté notamment), le coût du tunnel peut énormément varier. « Selon nos hypothèses actuelles, nous aurions des sols aptes qui permettraient de réaliser les travaux avec les moyens actuellement disponibles sur le territoire », indique le directeur de la DITTT.

Transit. « Dès que nous aurons l’avant-projet sommaire, nous le présenterons aux élus de la commission des infrastructures du Congrès. Ce sera à eux de décider si nous allons plus loin », explique Gilbert Tyuienon. Vu les études encore nécessaires, les travaux ne débuteraient pas avant 2015. Selon le vice-président du gouvernement, ce projet s’inscrit dans une vision à long terme, faisant de la route Nouméa-Tontouta un itinéraire de transit, avec un temps de trajet optimisé. Et ce d’autant plus que le gouvernement s’apprête à lancer une étude de faisabilité sur le transfert du trafic de l’aérodrome de Magenta vers l’aéroport de La Tontouta (lire ci-dessous). Le développement de l’agglomération se poursuivant vers le nord, le long de la RT1 : « Les gens de la Zac Panda iront plus vite à Tontouta », illustre Gilbert Tyuienon, qui a demandé à la DITTT de se pencher dès cette année sur l’étude d’un passage à 2x2 voies des tronçons entre Païta Nord et Port-Laguerre, ainsi qu’entre La Tamoa et Tontouta. Un élargissement qui est « encore possible à réaliser sur place, car les abords de la route restent peu urbanisés. » D’où une certaine urgence à geler les lieux. Mais la Pirogue reste le premier nœud à dénouer et l’avenir dira si cet ambitieux projet quittera enfin ses habits d’Arlésienne.

Until Mayotte will be declared an overseas department on 01.01.2014 La Reunion is the southernmost part of France.

New Caledonia is not a French possession. France hasn't had possessions since 1946. New Caledonia is an integral part of France, with a different status than the overseas departments. Claiming that New Caledonia is not part of France because it has more autonomy than the overseas departments is as stupid as claiming that Scotland is not part of the UK because it has more autonomy than the English counties.

1- La Réunion is more to the south than Mayotte.

2- Mayotte is already an overseas department of France. 2014 is the date at which it will officially enter the EU.

That's a lot of money. 1.6 billion € for 840,000 people. Compare that to the 27 billion euros that will cost the Grand Paris subway that will serve 12 million people.

What's this exit on the right not covered by Street View? From the map it seems there's a tunnel under the Arch of Triunph.

Boulevard Périphérique

The boulevard périphérique in Paris turns 40 years today.

On 25 April 1973, the final segment of the BP opened to traffic. Construction on the 35 kilometer inner beltway of Paris lasted 15 years from 1958 to 1973.

A63 Bordeaux - Bayonne

Two stretches of the N10 in Les Landes are now widened to 2x3 lanes and tolls are imposed as of today. They are the northernmost 15 km of the former N10 and the southernmost 10 km. The speed limit on these stretches is now 130 km/h.

About time. It was a pain to drive 110 km/h through that endless land.

http://www.a63-atlandes.fr/
yes, normally 130 km/h between both new tolls, but only 110 km/h on a big stretch because there is still works.
Toll payment at 50 % of the final value for cars up to the end of the year and 80 % for heavy vehicles.
I drove on this new part today, but 300 meters with queue to pass the northern toll for people without electronic system.
End of works and opening of the entire section in december ,normally.
