I think AMC is exit 2 but to take exit 2 you have to follow the lanes for A9 after exit Abcoude.

Great video Chris! Looking at freeways of The Netherlands always reminds me of the Stockton/Sacramento area of California. Now, if only our freeways looked as pleasing to the eye as Dutch ones!... Sigh.

On the other side, I barely dream of seeing any typical American freeway moving fleet on Chris Dutch highway videos... I've never seen a Suburban, Trailblazer or 4Runner on our roads...

You occasionally see one here in the UK. In Norway, I saw quite a few. There has to be some in The Netherlands somewhere. :-)

I'm surprised to see that it narrows down to only two lanes as it's approaching the A10. Isn't that a problem during morning rush hours? Was that a deliberate attempt to steer traffic flows in the area or were there other reasons?

PS: really awesome video, btw

The idea is to widen A2 within interchange Holendrecht to 2x5 lanes. However, this will consist by adding a 3rd lane from A9 to the Ouderkerk exit, and it looks like that small 2-lane section will remain at the northern section of interchange Holendrecht. Apparently, 2 lanes is considered enough to handle the traffic flow towards Amsterdam.

The intersecting A9 will be widened to 2x4 lanes towards Schiphol (west), and 2x5 lanes to Diemen (east).

It has to be noted though, that most major job centers in the Amsterdam region are south of the North Sea Canal / IJ River. Therefor, the amount of through traffic from Utrecht to the north of Amsterdam or further is pretty limited. A9 will absorb a lot of traffic coming from Utrecht.

However, my gut feeling is that 2 lanes will not be enough in the further future, especially not with all the developments along A10 in the South of Amsterdam. However, it also has to be noted the full 5-lane capacity will not be used for at least another 5 - 10 years.

As Chris says a lot of traffic on the northbound A2 heads towards Amstelveen and Schiphol Airport via the westbound A9. So the northbound 2 lanes are hardly a problem currently.

Southbound the 2 lanes at KP Holendrecht are a bigger problem and causes jams on a daily basis.

The section Holendrecht-Amstel will be a problem soon after the Utrecht land tunnel will be opened. However there's no money to start a project. Although with simple adjustments of only M€ 10 (including an EMA for 1000 metres of real widening with 1 lane) this could be solved. Well, I think the money comes after all when the problem will arise visibly...

A5 Amsterdam

The first of a series of lateral beams of the A5 will be placed tonight. The first one is 27 meters long, and the longest constructed so far in the Netherlands. Dozens more will follow suit. They will bear the 3.3 kilometer long elevated motorway in the industrial west of Amsterdam. It will be the longest elevated motorway in the Netherlands. Completion is planned for 2012, with a full opening in 2013 because the old Coen Tunnel will have to be renovated once the second one is completed.

Asphalt types in the Netherlands.

asfalt by Chriszwolle, on Flickr

Green = types of porous asphalt
Blue = regular dense asphalt
Purple = concrete

As you can see there isn't much concrete (the A1 section has just been repaved with asphalt). The majority of the motorway mileage has porous asphalt.

Porous asphalt? What is that?

Here we have asphalt, concretic (dunno what that is, but have seen it in tenders for paving contracts put out by the Ministry of Transportation and Infrastructure) and sealcoat (chip seal) Some roads are still gravel/dirt. Rougher than s**t too, but those are mainly forestry/logging roads.

Porous asphalt has superior drainage and noise features, but is more expensive and less durable. Apart from the Netherlands, it's also used extensively in France and Italy. Other countries do not use it as much.

porous asphalt is type kind of asphalt that contains bigger granulate (stones) and thus bigger voids in between them. We call it 'very open asphalt concrete' ('zeer open asfalt beton' (ZOAB).
This type of asphalt reduces noise considerable and gives water more room to flow away and thereby reduces dangerous situations with hydroplaning or aquaplaning.

And, also important, reduces splash to near-zero, thus avoiding that capacity decreases during precipitation on our saturated roads.

I think this kind of asphalt is extensively used in GB. There is significant difference, though in noise level between recently laid-out sections comparing to older ones.

In Italy, Autostrade per l'Italia claims to have covered with porous asphalt 81.6% of its network
Quote:
corresponding to 100% excluding tunnels, mountain sections and sections under widening works.
Autostrade per l'Italia does not run all Italian autostrade, so there are sections where porous asphalt is not laid down yet.

However, you can really see the difference, expecially in terms of splashes, as Chris previously said.

Just got back from Amsterdam, the new section of the A2 is cool, on the way five lanes were open and we were very late because of the French N roads, so we bombed along the A2 to make time up around Utrecht, the left two lanes were deserted. On the way back only three lanes were open and there was a long traffic jam; it took five hours in all to reach Calais because of delays around Amsterdam, Utrecht and Antwerp.

You do know the 100 km/h limit is often enforced? Unfortunately, it can cost you quite some money to "bomb along A2".
