I like Turbo Roundabouts, but they are confusing for a nation taught to use multi-lane roundabouts properly.
But overall the two lane roundabout is pretty odd with the concentric lane marking. How is that thing supposed to actually work? (rather... what do you do in the inner lane?)

The type with the lane markings that try and send the outer ring in tangential directions (ie straight or right, or straight and left for UK) while left (right) turns are for the inner circle seem easier to figure out... but still a bit of a leap of faith not to have your door smashed

@joshsam: It's an original and good campaign "minder zuur achter 't stuur". But these things are not limited to Belgian roads only. It's a general thing. Also in the Netherlands, France, ... people often don't use indicators, ...

This creates possible conflicts, especially if straight through traffic is heavy.

Turning it into wide single lane roundabouts is a bit unorthodox, perhaps inspired by the huge unmarked traffic circles in Paris.

Basically, three solutions are possible;
* turn it into a turbo roundabout. Leads to more efficient use and predictable behavior. Requires complete reconstruction if done properly.
* narrow the road to single lane just before the roundabout. Only possible with low volumes. Relatively cheap.
* turn it into a signalized intersection. Preferred if it is a busy road with a lot of through traffic. Substantial investment needed, plus operational costs of traffic lights.
Drivers behaviour in a multi-lane roundabout is no less predictable. Drivers in the right hand lane can only turn left where this is clearly marked. Such a design is rare, however. In most other case is the left lane for left-turns, the right lane for right-turn and both lanes for straight-on traffic or maybe the middle and right hand lane for the latter. I really don't know where you see difficulties with multi-lane roundabouts. They work pretty fine actually. They are in fact the saving grace for the entire British road network.

R4 Gent

A new segment of R4 opened to traffic in Gent.

The southern part of R4 around Gent consists of two one-way roads on either side of the canal. However, a part of the eastbound road was missing, forcing motorists to take strange detour routes near Zwijnaarde.

The currently opened segment of R4 utilizes a new bridge across the canal and the offramp of the eastbound road extension.

Question...

What are the names of lighting column manufacturers who made those curvy steel poles on Belgian motorways and highways (seen with Schreder GSO as an example)?

I know Baert en Zonen which is a big player in lighting poles. But there are several.

Hello, isn't any of you familiar with this building? It is probably in Belgium and was shot in 1930.

There are probably hundreds of churches like those in Belgium... I can't tell.

It depends on whether the design is older or more recent.

The image above compares two designs in the UK. Both allow traffic approaching on the left lane to go straight ahead (the green line), whilst right turning traffic can simultaneously turn right (the yellow line). The top image is an older design. The bottom image is a new design built to the latest standards.

On the latter newer design the much tighter approach angles and deflections (as required by standards) is supposed to slow traffic down as you are expected to turn sharply as you enter the roundabout to keep to the correct lane, rather than the old design that almost guides you in a more natural line into the correct path. As the green and yellow lines show people will still want to take a more natural line and the new layout shows how it encourages drives to take a racing line across the roundabout. This is dangerous as there are far too many numpties that will move across all lanes to go straight ahead without checking whether there is someone alongside them turning right.

Thanks to this backward step in design standards, I've nearly been sideswiped many times on these types of roundabouts. The geometry in attempting to slow traffic just encourages traffic to appropriate them badly.

Why do you think this is in Belgium? Doesn't look Belgian too me. And the cars drive at the left hand side of the road.
Edit: maybe Sweden?

E313 Viaduc de Boirs

The regional newspaper Het Belang van Limburg reports the E313 Viaduc de Boirs will reopen with all lanes in the next week. The 1964 viaducts have been replaced, a job which took 7 years. The project was critized for its slow approach. The old viaducts were in very poor condition with chunks of concrete falling down and rebar being visible. They were judged to be beyond repair. There was a 7-year 2-0 workzone, but there wasn't much congestion due to the low traffic volumes (<20,000 vehicles per day).

Thanks for posting that info. I been there every summer since 2010 and I was always rather suprised that they were still working on that road and that it seem to take years. I always thought it took so long because the E313 crossed the Flemish-Walloon border around the Viaduc de Boirs.

A11 Brugge - Westkapelle

Construction of the new A11 officially began today. This is the first new greenfield motorway in Belgium in nearly 15 years. The new motorway is 12 kilometers long and improves access to the Port of Zeebrugge. The new motorway is planned to open in late 2017.

Because I found it in a photo album where the rest of images were surely made in Belgium. And actually the architecture style, too, is quite Belgian-Dutch.

Can you say something about the other pictures? Were they all in the same region? And are the cars driving at the right side of the street?

Sorry, I don't want to conduct an abszolute off topic discussion in this thread, it was only a quick try :-)
You may be right about left side traffic, however it is possible that the image was processed in a mirrored way. If I check the clock of the tower, it seems to be mirrored. If the image is mirrored, it means that the cars actually drive in the right side.

All the rest of the album are definitely photos about the World Fair of 1930, Liege and Antwerpen. None of them has any cars.

Actually, I don't think it's a church. It seems much more to be a town hall or something similar, photograhped from aside. The main facade is in the left hand side of the picture. Possibly neogothic style, 19th century, but it is only a guess :-) I checked lots of buildings in Belgium and even in the Netherlands but did not find anything, so I asked here, hoping that perhaps someone recognizes it immediately. It didn't happen. Life goes on :-)

It could be a belfry (bell tower and townhall), but that would narrow the search down a lot. There are only 56 belfries in French Flanders and Belgium.
However, belfries are much older than the building in the picture and usually situates on an central square of the city.

This looks like a suburban church
