But it's not the main highway, you know what I mean. And btw, I'm not saying this as an excuse. It's a scandal. I've read the official explanation in the paper today: this part was scheduled to be renovated this year, but due to budget issues it's postponed to next year...

Wait a little longer and it'll be less renovating and more reconstructing. You might even find some archaeological treasures.

Does it matter which part of the highway, any part of the highway looking like that is a disgrace.

The highway itself looks like this: https://www.google.be/maps/@51.37613...RtouTNso7w!2e0

The streetview pictures are dated, but even at that time the dutch section looks better, and on the first picture of the border the dutch section is already repaved.

The difference in maintainance (look at the overgrown median) at A67 is big as well, if you go back 100m in to the Netherlands there is even a sign that says watch out "slippery road".

Maybe the Belgos could just pave it with cobblestones. They don't wear out as quickly and since they're absolutely ruinous on caravans, all the Dutchies would go to Germany in the summer instead. Win-win.

Even using it, you'll get just about 80-90 m more, not a big difference. And at the price of having no margin at all, which would be an even less safe situation.

Here I made the rightmost lane merge, but if they want to keep their damn taper they can. At least it will be a 450 m taper instead of 100...

Tell RWS I'll send them the bill.

Other countries often have similar things, but they don't provide any guidance at all to the incoming traffic. E.g. here: https://www.google.nl/maps?ll=48.716...4,,0,7.54&z=19 Just seek your own way from 2 lanes into merging. Look left of you - and right, because you never know what anyone will do. The taper-solution in NL is way much clearer to a road user, and is being signed in a way anyone driving towards the taper can anticipate. Sign: https://www.google.nl/maps?ll=52.056...126.4,,0,10.12
The taper is fine, but this one looks extremely short, it must be possible to make it slightly longer no?

Actually, probably the shortest taper in NL is probably on the A13 at Delft-Noord in the direction of The Hague. It's even shorter than the one onto the A12 at Prins Clausplein.

They are busy removing the border station now, and the traffic is being diverted around through a temoraray road. But you very much notice the difference when entering Belgium from France. It wasn't that bad let's say 6 years ago.

Edit - actuially it's the border station on the E17 that is being removed, but the E42 is still very bad...

I vote for the N7 at Groningen

It's a bit cheating though, since either the left merge lane is closed or the right lane of the N7 is closed. So traffic does not come into conflict, which is most certainly a good thing

There is still no way that you can merge using the second lane without either straddling the first lane or crossing the solid markers...

The "controlled taper" used in Groningen is a nice solution. A bit less flexible, but still you don't have a permanent loss of capacity.
To be perfect it would need variable road painting

About Delft Noord: does that on-ramp really need two full lanes all the way in? All other junctions on A13 seem to be designed (or modified) with 2>1 reduction before the merge.

There's a taper at the Neerbosch motorway interchange near Nijmegen (where A73 makes a TOTSO) where the tapering lane is always crossed out by the matrix signs when I drive there.

It's about 100 meters long, and thats not "extremely short". A lot of tapers that are safe and are functioning well have about the same lenght.
Two examples:
https://www.google.nl/maps?ll=52.424...04128&t=h&z=19
https://www.google.nl/maps?ll=52.437...04128&t=h&z=19

Although tapers of 200 meters are better, that's evident.

An example of a really extremely short merging taper (ca. 50 m):
https://www.google.nl/maps?ll=52.029...04128&t=h&z=19
This one is really too short for being permanently openend from both directions.

This one is also only 50-60 meters:
https://www.google.nl/maps?ll=52.354...02064&t=h&z=20
But in this case the taper is never used from both merging lanes at the same time. By default the tapering lane from the A1 is closed - and when it is opened to relieve congestion on the A1, the right lane on the A10 is closed.

I wonder how many roads as dangerous as N65 are left... with crossings like this one or that one (imagery is old)

A1 Amersfoort

The final EIS has been published for the widening of A1 between Bunschoten and the Hoevelaken motorway interchange. It is basically the northern ring road of Amersfoort. They will widen the eastbound carriageway to three lanes. A bridge across the Zwolle - Amersfoort railway will be replaced, with sufficient space for a future expansion to 4 eastbound lanes.

It is a temporary fix to prevent a bottleneck once the A1 is widened from the Eemnes motorway interchange (A27) to Bunschoten. Without the temporary widening, the amount of lanes would drop from 4 to 2 at the Bunschoten exit.



There will be A LOT of construction going on in the Amersfoort area, starting in 2015. It will basically be one big construction zone from 2015 to 2022. There are three separate projects;

* 2014-2015: widening of eastbound A1 Bunschoten - Hoevelaken to 3 lanes
* 2015-2019: widening of A1 Eemnes - Bunschoten to 2x4 lanes
* 2019-2022: reconstruction of Hoevelaken interchange
* 2019-2022: widening of A1 Bunschoten - Barneveld to 2x4 lanes
* 2019-2022: widening of A28 Amersfoort-Zuid - Nijkerk to 2x4 lanes

The A1/A28 eight-laning projects are part of the Hoevelaken motorway interchange reconstruction project. It is the final project to widen all motorways around Amersfoort.

Do you have any designs of the new Hoevelaken interchange?

The design reference for the whole project can be found here (large PDF), nothing final yet but I can't imagine they'll stray too far from what they've already got on paper.


This is the interchange itself:

Does this really count as dangerous design? It's clearly far safer than a single-carriageway 1x2 road for example, you have the space to wait between carriageways, etc. It is only dangerous if the traffic volumes are very high in the main axis or high in the cross axis...
