D173 Ille-et-Vilaine

A 6.8 kilometer segment of 110 km/h, 2x2 voie express opened to traffic on January 31 (according to Wikisara) between Retiers-Sud and a locality known as La Noë Jollys.

It is part of the Axe Rennes - Angers, a four lane road that links those cities. Not all of D173 is a grade-separated expressway, there are a few roundabouts closer to Rennes. The newly opened segment appears to end at a temporary terminus north of Martigné-Ferchaud.

Another segment southeast of Martigné-Ferchaud to the Maine-et-Loire boundary is also under construction, which according to Wikisara will open in September 2017.

Gotta love the skiing trip to France. Only 3 hours delay between Lyon and Moûtiers.

TomTom says there is alternating traffic east of Moûtiers, which results in 1.5 hour delays in both directions.

N145 La Souterraine - Guéret

Some photos of N145, an east-west voie express in Central France. It links A20 with A71 near Montluçon, and is part of the RCEA concept. It was built mainly in the 1990s and 2000s, the final segment opened in 2011 around Montluçon.

From a landscape perspective, it was a positive surprise, possibly the most interesting autoroute or voie expresse in Central France, north of Auvergne. It is fairly hilly and the road keeps you entertained despite its 110 km/h speed limit.

An amateur video shot yesterday which shows the eastern harbor of Réunion's seaport, where the elements of the piers as well as the 'voussoirs' (upper segments of the bridge which will rest over the piers) are manufactured. The mega-barge Zourite comes to the eastern harbor of Réunion's seaport to load each element of the piers one by one, and then travels to lay them on the ocean seabed a few kilometers away.

A9 Montpellier

It has been announced that the new A9 around Montpellier will be inaugurated on 10 March. The opening to traffic will be 'before 15 June'.

Was it really so necessary to displace it a few hundred meters? Or maybe the old one will remain as a "tangenziale" or local bypass?

The old A9 will remain in place for local traffic (it will be renumbered A709). The new one means that traffic will be free-flowing (no toll booths) around Montpellier, and capacity will be doubled.

It will drastically reduce summer congestion. On busy summer days, traffic volumes on A9 approach 170,000 vehicles per day which overwhelms the toll plazas and mixes with local traffic.

With the new A9 bypass, through traffic will stay within the closed toll system while traffic to, from and within the Montpellier area will use A709 (old A9). They say it will become a 'boulevard urbain' but I don't think they will install traffic lights or roundabouts. This also doesn't make sense as it will remain a high-volume motorway and it runs mostly through industrial and commercial areas on the edge of Montpellier. It doesn't slice the city in half like the former A4 in Reims.

N19 Sevenans

Construction has started on a new N39-A36 interchange near Sevenans, just south of Belfort. It will link N19 from the west, N19 to Switzerland with A36. Construction will last until 2020.

A9 Montpellier

The new A9 around Montpellier was officially inaugurated today. However, the project is not yet completed and may not open to traffic for at least several months, so it seems a bit like a political ploy ahead of the presidential elections in late April.

At least in Spain that's also very common, even when there's just a single road on each side of the highway; I guess it has to do with lower construction costs: building a single roundabout above the highway needs two different bridges, while a roundabout on each side just requires a single albeit wider bridge.

In any event, newer interchanges in Spain have, when possible, a single roundabout above the motorway rather than two different roundabouts on each side of it.

No presidential inauguration apparently!

It is not yet known whether the bridge will then be opened to car traffic, or whether it will just be an official inauguration to make departing ministers and president feel good about themselves, as in the case of the new A9 around Montpellier. In any case, even if they open the bridge to car traffic, it will take until at least the summer for the Brazilian authorities to finally have an operational customs house on their side of the bridge, so that in any case truck (freight) traffic won't be allowed before the end of the year.

Let's also note that the final stretches of the muddy track between the international bridge and Macapá (capital of Amapá state) won't be paved (and proper bridges built over the rivers) by the Brazilians before the end of 2018 (the pavement of this road is 40 years behind schedule, and the federal authorities of Brazil have now decided to take over the project themselves, with the army if necessary...).

This report from 2014 shows the state of the Brazilian road between the international bridge and Macapá during the rainy season of 2014. According to the report, 113 km of dirt/muddy tracks still needed to be paved (and proper bridges built; currently there are only rickety wooden bridges) to complete the 500 km road between the French border and Macapá. Brazilian people in the report say local corruption in the state of Amapá is responsible for this (federal funds sent to Amapá are embezzled and do not achieve anything). The former governor of Amapá has been indicted for embezzlement of public funds, the new governor appears to be more dynamic, and federal authorities have now taken over the issue themselves like I said.





On the French side, the new bridge over the Comté River, which will allow heavy trucks to cross the river (currently the old one-lane bridge allows only small trucks weighing less than 28 tonnes) is under construction and will open to traffic this coming July. The new bridge will be a two-lane bridge allowing trucks weighing up to 100 tonnes.

That's the current bridge over the Comté River. It's a portable, pre-fabricated Bailey bridge that was installed in 1973 at a time when French Guiana was 5 times less populated than today:







And that's the new bridge that will open to traffic in July (the old bridge will be entirely dismantled, piers included):





A report from last January showing the new bridge over the Comté River under construction:



So heavy trucks should be able to drive between Cayenne and the Brazilian town of Oiapoque by the end of the year, but do not expect any heavy truck between Cayenne and Macapá before early 2019 at best! Anyway, we're slowly getting there... The bridge was completed in August 2011 and has been sitting unused for 5 and a half years now.

The answer is simplicity and familiarity. One aims for junctions which are simple and familiar. The traffic flow on two small roundabouts is easier to understand than on one large oddly shaped dogbone.

Now that I'm watching the last stage of the Paris-Nice cycling race, I remember noticing the other day this 45 km/h speed limit sign: https://goo.gl/maps/g6Uvx5g1Rk72

I reckon that the sign must be at least 30 years old. Are such _5 km/h speed limit signs still used in France?

You can occassionally still spot those. They seem pretty rare though.
