That would have been a better motorway.

The speed limit has nothing to do with the width of the road, but with an agreement between the national government and local municipalities. The road after the widening was originally going to be 2x4 lanes, but for the future that wasn't enough. The national government made a deal with the municipalities to prevent them from protesting against the 'extended' widening: the highway will be made wider (2x5 lanes) and the speed limit would be lowered to 100 km/h (the old extremely congested 2x3 highway had a speed limit of 120).
And that is the reason this is 100 km/h...

A6 Almere

Construction on the second "Hollandsebrug" (Holland Bridge) at Almere officially began today. They will construct a second bridge for the widening of A6 through Almere.

The bridge will be completed in late 2015, so construction will last approximately 1.5 years.

The new bridge will feature 10 motorway lanes, 2x4 lanes plus two reversible express lanes (untolled). It will also feature a local road for slow traffic, a two-way busway and it located next to a railway bridge and power lines, so you don't get much more infrastructure than here.

The projected 2030 AADT is 204,000 vehicles per day.



The existing bridge:

Jutphaas Bridge, Utrecht

The Jutphaas Bridge (Jutphasebrug) is a steel arch bridge across the Amsterdam-Rhine Canal at the border of Utrecht and Nieuwegein. It was built in 1936.

It's currently undergoing major renovation. A temporary bridge has been constructed while the old bridge is moved out of traffic and gets renovated. The bridge will be shifted back to its original position in 2015.



It's part of Project KARGO (Kunstwerken Amsterdam-Rijnkanaal Groot Onderhoud), Bridges Amsterdam-Rhine Canal Major Maintenance) which replaces or renovates 8 bridges across the Amsterdam-Rhine Canal. It will also improve shipping clearance for another stack of containers.

I got the train from Amsterdam to Leeuwarden last week and I was surprised to see a 1+1 dual carriageway between Lelystad and Dronten (N307). I guess this is good for safety as you cannot overtake. But I guess it would be frustrating being behind a truck and knowing you can't pass. Are there any other 1+1 dual carriageways in NL?

Near the exit Swifterbant there is an overtaking oppurtunity where the road becomes 2x2 for a bit, as you can see in this video made by Chris(Zwolle)

There are plans to give the N18 section between Groenlo and Haaksbergen a 'super-two' layout.
And that's all that I know of. Uhh. The N35 tunnel through Nijverdal will have this lay-out, but that's a tunnel and I don't know if that counts

There are also parts of N57

Not by a lot of countries...

In Japan in rural areas as expressways. If traffic volumes on the expressway go up they can quickly expand it to 2x2 lanes
In France in the quieter areas they will sometimes have a 2x2 highway narrow to 1+1 to cross over a road with a viaduct and then after crossing that road the highway will go back to 2x2.

For anyone that even remotely likes driving, yeah these are a pain, as you're stuck to driving in trains behind the slowest person on the road.

Safety wise, it's undeniable that these are very safe roads, compared to ones where you can overtake.

I'm not a fan, but I don't find it a bad design. I do find it ridiculous, that on most of these roads very little extra work is needed to make a 2+1 design instead ( if any), which is obviously much less of a pain to drive on.

Now on the N57 in Zeeland you're mostly restricted to overtaking on them Turbo Roundabouts, which in all honesty isn't so safe. I had to literally pass them with skidding tyres on the roundabouts to overtake that one annoying ****er going under the speed limit ( but bombing it over the roundabouts).

I think it was Zeeland that wanted to restrict overtaking physically ( eg. by barrier) on all provincial roads ( that don't have 2x2) ?

In the case of the N307, did they build such a wide median so that it is easy to upgrade to 2+2 in the future, if traffic predictions warrant it?

Yes, N307 is part of the "N23" project, which is a planned expressway / divided highway from Alkmaar to Zwolle.

Are you sure it is? I mean you have risk of rear-end collisions, and risk of people just going and passing anyway on the grass or close to the other car...

You have that risk on every road.

You can have that on a 'normal' road as well but then on the other side of the car into oncoming traffic.

I just realised that the truck speed limit in NL is the same as the car speed limit on regular single carriageways at 80 km/h. So on a single carriageway, you shouldn't need to pass a truck going at the speed limit. That is rather different to the UK where the car speed limit is 60 mph and the truck speed limit is 40 mph on single carriageways, even on a high standard single carriageway that would be classed as an autoweg in NL, like at the beginning of the N307 video.

So even on the N307, cars would still be able to do 80 km/h if stuck behind a truck, so no worse than a single carriageway. I realise the car limit is 100 km/h, but arguably it isn't that much different than a single carriageway as it is only 1 lane for most of the way.

Realistically even 85-90, depending on how high the limiter is set

The real tragedy are not trucks, which try to travel as fast as they can, but those car drivers who can't keep the proper speed for no reason...

Wouldn't limiters normally be set to 90 km/h, as that is the truck speed limit in many European countries?
