N19 is a long-term plan to upgrade the route to serve Paris - Switzerland traffic.

Very very long term project as the essential part between Port-sur-Saône and Langres will remain a simple road for decades are there is still no planning to make it an express way (or a possible highway like they were talking...) and the actual objective is for 2030-2050...

Maybe this could change with a strong political lobbying from local politicians, but most likely not...

(My family lives there, that's why I follow the news about this road... )

No, it is talking about population for green signs, but they are also saying that population levels are only an indication on the sheet and that the classes III, IV and V are determined by the ministery (V = national/european interest ; IV = regional/national interest and III = departemental/regional interest)...

It's interesting that Google Maps takes Paris - Basel via A5-N19 already - despite it having long stretches of two-lane roads. It's still the fastest and by far the shortest route, being 52 kilometers shorter than A6-A36 and 104 kilometers shorter than a northern route via Metz.

Although A6-A36 is only slightly (minutes) longer in travel time, it's also more expensive due to the tolls (almost twice as much).

A20 Vierzon - Châteauroux

A20 is one of the four major north-south axes in France, it runs over 406 kilometers from Vierzon to Montauban. The only major city en-route is Limoges. It ends north of Toulouse.

A20 serves the Limousin region, as well as the more popular Dordogne region. From a landscape perspective A20 is less interesting than A75. The hills are lower and the landscape is sometimes just flat. The landscape between Châteauroux and Limoges is very similar to that of central Germany; low hills with a lot of forest. The northernmost part is more open and rural.

The motorway was built in stages, mostly during the 1980s and 1990s, when it replaced N20. The first segment opened near Pierre-Buffière in 1979, the final segment opened in 2003 near Cahors.

The majority of A20 is untolled. The tolled segment runs from Brive to Montauban (through the Dordogne). The toll rate from Paris to Perpignan is exactly the same when you use A20-A61 or A71-A75.


1. A20 starts at an interchange with A71 in Vierzon. Exit numbering starts at 5.

2. The next larger town is Châteauroux.

3. Vierzon has three interchanges along A20. Its central position in the French autoroute network (A20, A71, A85) gives the city of 40,000 some status among long-distance travelers.

4. The northern part of A20 was built mostly over or next to the old N20, except at towns and villages.

6. Graçay.

7. Vatan. This village has two partial interchanges.

8. Brion.

9. Châteauroux is slightly larger than Vierzon and the second-largest in the region, after Bourges.

10. A20 runs west of Châteauroux. The 17 km distance is going to the southern interchange, and then drive all the way back into town.

N353 Strasbourg

Construction has been accelerated on the N353 extension southwest of Strasbourg. They will construct a four-lane voie express from the D1083 cloverleaf to A35.

It's only about 3.5 km long. The southern bypass of Strasbourg is a relatively new development, planning started in the late 1980s, but the first section did not open until 2000 (including the cloverleaf with N83 - now D1083). The Rhine Bridge to Germany opened in 2002.

The western extension to A35 is planned to open in 2020. The detailed schedule can be found here (gotta love the French regional website URLs... )



The N353 / D1083 cloverleaf. Not much work is needed here.

Montpellier

The consultation for the western bypass of Montpellier has started today.

The western bypass of Montpellier will link A750 and A9 by a voie express. It is presently mostly a two-lane road with roundabouts.

The planned upgrade is budgeted at € 230 million. Construction could start in 2020.

You can download some graphics and information here (lots of visuals, also understandable for those who don't speak French).

Only 67 characters for the domain? That's way too short . Anyway they are renaming the region to Grand Est (Greater East), although I still recognize it as the three separate regions of Alsace, Champagne-Ardennes and Lorraine.

That's a very important improvement in a metro area with almost no expressways. Traffic conditions in Montpellier will be a lot more bearable with this and the new A9. I hope it doesn't get washed down to a two-lane road with roundabouts like in Antibes.

Montpellier is very sprawled out. There are a large number of villages in the region that have grown to nearby and distant suburbs of the city.

Both A9 and A750 play only a limited role for metropolitan traffic. Most traffic is handled through two-lane or sometimes dual carriageway departmental roads, often riddled with roundabouts.

They built D68 as a northern bypass, but it's on the outer fringe of the region, not doing much for intra-regional travel.

A304

A304 is a new untolled motorway in Northern France, from Charleville-Mézières to the Belgian border, and further on N5 to Charleroi. It has been delayed several times.

The northern half of the project is less advanced.

Yes, that's right. The plan is to build a Charleroi - Reims dual carriageway.

Dual carriageways in Belgium have a 120 km/h speed limit by the way, even when they don't have motorway status and even when they're not grade-separated and allow cyclists.

I was in France on holiday at the beginning of September. From driving quite a few roads there are some curiosities.

Adverse cambers, say on a long sweeping left curve of autoroute, the road crossfalls to the right.

Again, adverse cambers, this time on roundabout. I presume this is to slow traffic circling the roundabout? Plus a lot of cases where a two lane carriageway will funnel down to a single lane approaching a roundabout.

Entry angles onto roundabouts are tight, so much so that traffic taking the first exit will drift towards the middle of the roundabout rather than hug the outer edge - a bit dodgy if the entry to the roundabout is more than one lane, promoting the greater risk of entry path overlap.

Yea adverse camber on French motorways puzzles me out too. There are a few examples on N113 and A54 East of Arles. Car stays planted on the road because the bends are gentle, but I haven't seen it anywhere else.

Yes, I also saw that, it's quite weird. But maybe the best explanation is because they precisely want to prevent this from happening:

D177 Axe Rennes - Redon

A new segment of 2x2 voie express between Rennes and Redon in Western France will be inaugurated on 9 November. It's a 4 kilometer segment between Guignen and Lohéac. Traffic will already be using it next Monday when one side opens to traffic with one lane each way.

Bordeaux

Proposals for a second ring road of Bordeaux have been floated around for some time. A new proposal says the current ring road could be made a one-way road, with 4 to 6 lanes in one direction.

A problem arises with that, it would increase traffic on nearby city streets that wants to travel against the direction of the 'roundabout', and through traffic from A62 to A63 for example would need to take a huge detour to get around Bordeaux.

A completely stupid new proposal by a local politician who never takes this ring.
I often drive on this ring and since 1996 the only improvement was the widening to 2x3 lanes on the south and east sides.
A second ring road must be built by the east (for me) to connect the four highways that arrive in Bordeaux more the RN 10 borrowed by thousands of TIR trucks daily.
But all good proposals since I drive there were stopped by politics due to the cost of this second ring and by crossing the vineyards, rivers, and villages.
A toll would be necessary and unavoidable.
