I think Bordeaux ringroad is too large to be made one-way. This arrangement may only work for small inner city ringroads (1-2 km in diameter), like in Charleroi or Treviso, where driving 3/4 of the circle instead of 1/4 isn't a big detour.

The Bx ringroad is 45 km.
I don't imagine a roundabout of this length with 6 lanes.
But, does anybody know where in the world is the longest roundabout ?

Maybe Petite Ceinture (R9-E420) in Charleroi (5.1km)?

Thank you.
But I would rather have imagined that in a country with high density like Japan or in the USA.

I wrote maybe, so I'm not sure. There may be a longer one in USA, Japan, or somewhere else that I don't know.

Nagoya, Japan has a 'roundabout expressway' around the city center.

Well that's no problem for today's French politicians, they might as well close these city streets because some pollution/safety/health/whatever concerns.

I'm sincerely waiting for the moment when some flamboyant French major decides to close his or her entire city to automobiles declaring it to be the world's greenest, healthiest and cleanest city, and the subsequent chaos results in that major not being reelected. It will happen sooner or later.

No matter how stupid, if it can be done they will do it. And they'll do it even if it can't be done.

There was someone advocating the permanent closure of the Boulevard périphérique.

N19 Port-sur-Saône

Construction started Tuesday on a 7.9 kilometer segment of 2x2 voie express of N19 around Port-sur-Saône. This expressway will connect to the existing expressway west of Vesoul. It is planned to be completed by late 2020.

A20 Limoges - Brive

A20 between Limoges and Brive-la-Gaillarde.

1. Magnac-Bourg.

A20-78 by European Roads, on Flickr

2. Toulouse is still a good 2.5 hours away.

A20-79 by European Roads, on Flickr

3. Saint-Germain-les-Belles.

A20-80 by European Roads, on Flickr

4. Masseret.

A20-82 by European Roads, on Flickr

5. Uzerche, the largest 'city' between Limoges and Brive.

A20-85 by European Roads, on Flickr

6. The green signs are very helpful to locate routes to major destinations. Otherwise it kind of falls within the load of white signs to villages.

7.

A20-89 by European Roads, on Flickr

8. The first A89 interchange.

10. Lyon and Clermont-Ferrand.

11. Donzenac.

12. Allassac. There is a long descent into the Corrèze River Valley.

13. Ussac, and the east side of Brive. They built a bypass of Brive some 8 years ago.

N7 Varennes

The first stage of the bypass of Varennes-sur-Allier (N7) will open to traffic in Mid-December. It is 4.8 km long. Construction started in 2009, so progress is very slow.

It runs from D46 to N209, so it won't directly connect to N7 on either end, and will neither bypass the entire built-up area of Varennes.

Presently traffic through Varennes runs through two one-way streets, at times narrow and curvy. It is considered the most urgent part of the N7 from Moulins to Vichy / Roanne.

A8 Nice - Menton

The new Tunnel de la Borne Romaine on A8 east of Nice opens to traffic on 18 October 5 a.m.

It is a 755 meter long three-lane tunnel for eastbound traffic that bypasses a hillside prone to rockslides.

Construction took 3 years and has cost € 60 million. It is 5 m high, 12 m wide and 755 m long.

The first construction will likely start in July. The cost is € 120 million.
I drove there in early October but there were no construction works for new bridges. I just saw renovation works west of the easternmost A85 viaduct to be widened.

N2 upgrade

According to wikisara, two N2 sections should be upgraded to expressway standard by 2019. I saw construction works east of Lévignen (map) when I drove there 2 weeks ago. On the 2nd section, east of Villers-Cotterêts (I think it was here: map), I've only seen a big signpost but no works in progress. Does anyone have more info about these sections (when works have been started or are expected to be started, section lengths et cetera), for instance a project page link?

A20 Brive - Cahors

Some photos of A20 from Brive to Cahors, on a gloomy August day. Surprisingly the temperature here was 15°C lower than in Northern France the day before.

1. Brive-Centre.

A20-104 by European Roads, on Flickr

2. Brive-Ouest, old E70 sign.

A20-106 by European Roads, on Flickr

3.

A20-108 by European Roads, on Flickr

4.

A20-109 by European Roads, on Flickr

5. The last exit before the toll.

A20-111 by European Roads, on Flickr

6. The pavement instantly becomes the best you could possibly wish for on the toll road.

A20-112 by European Roads, on Flickr

7. Rocamadour.

A20-114 by European Roads, on Flickr

8. The toll station. It seemed rather small for peak summer traffic.

A20-116 by European Roads, on Flickr

9. The terrain becomes more hilly, characteristic of the Dordogne. It's not as spectacular as the Cévennes or Ardèche though.

A20-118 by European Roads, on Flickr

10. Souillac.

A20-120 by European Roads, on Flickr

11.

A20-121 by European Roads, on Flickr

12. Viaduc de la Dordogne. Possibly the largest viaduct on A20.

13.

A20-124 by European Roads, on Flickr

14. Cahors-Centre.

A20-127 by European Roads, on Flickr

15. Toulouse still an hour away.
