I was curious whether it just means that due to reasons unknown to me, the fuel sold here indeed has low octane rating, or somehow the numbers are changed but equivalent In Toronto the highest rating you can get is 91 (as far as I know), and most people use 87 because of rising prices (yes, I do know that you guys pay much more, but people here still don't like to pay).
Unlike what some have been saying, the octane ratings are generally equivalent for gas in N.A. and in Europe, however, we have a different way of calculating the numbers. Europe strictly uses the RON number, while North America uses an average of the RON and MON number (thats why above the octane rating, there is a little thing that says "R+M/2 method")

MON is usually about 10 points below the RON for equivalent gasoline, thus the lower numbers over in the US and Canada.

87 + 4 or 5 still only makes 91/92 though.
Anyways, does somebody have some construction updates?
I'm intrigued by that land tunnel thing.

Yep!

It is an international forum...

Let keep it the international standard: t.i. meters. How much is 50 feet?? Beside the philipines and the USofA nobody knows

Thanks, I should have looked at the article earlier. It is interesting indeed, but from the article the conclusion is still that the US and Canada generally provide lower octane fuel than the rest of the world (or at least, Europe), since our "best" rating is equivalent to Europe's "regular", and most often lowest, whereas our "regular" (87) is equivalent to about 92 in Europe, which is below anything they have, except for Germany I guess (which I know from this thread ).

Just a few planned routes on this map are never realized or differ from the present situation by location.


Road number 3 from Amsterdam-Gouda-Rotterdam would be a good option to solve a lot of traffic problems between The Hague and Rotterdam and also from The Hague to Amsterdam.
It would reduce also the time with 10 minutes I geuss if you drive from amsterdam to Rotterdam on a new motorway indicated on that old map.

Don't count on it that A3 will ever be build.

Meanwhile, our key mainport is inaccesible at the moment. 3 trucks crashed at the N15 expressway near the Maasvlakte (Europort Rotterdam), and the motorway is closed and there are no alternative routes. This means one of the largest harbors in the world cannot be reached.

Trucks are advised to find a parking space asap, since there are very few parking possibilities west of Rotterdam. The crash site is said to be a disaster. No pics yet.

I was not counting on it. But I still think it is essential. a 3 lane motorway would serve the 2 biggest cities in The Netherlands. Also traffic from the south is able to get faster in Amsterdam and other nothern parts of The Netherlands. The Randstad has to improve the infrastructure. It is a total mess every morning and afternoon.

'Het groene hart' is way too worthfull to build a motorway through. They better widen the existing A4 and complete (all of) the missing links in it.

Yep, the A4 and A12 should be widened to 2x5 lanes all the way.

Because they building one hundredthousand houses per year, and a lot of them is along or near these corridors, though they have the same capacity as 10 and sometimes 40 years ago.

Can one of the Dutchmen explain the colors on that old map?

It describes the importance of a road, divided into 4 categories, each by it's representative color as seen on the right of that map. In 1932, only the Randstad is seen as highest categorie.

True, and I think that is mostly because of a perception of higher octane = more fuel economy, which isn't necessarily the case.

No, it was the goal, but it turned out 78.000 homes build in 2007. Usually not close to work locations, and you do the math if this happens every year.

Then they should build another aquaduct or bridge under/over "De Ringvaart Haarlemmermeer".
Are there any plans in the future for that part of the A-4?

It is already planned, but there are still some difficulties.

This stretch of the A4 is the #1 traffic jam spot in the Netherlands, and has often accidents. On Monday 3 trucks, and a couple of cars smashed into eachother in this narrow aquaduct, that has narrow lanes and no shoulders.

This is a picture of the Ringvaart Aquaduct near Leiden. Over 107.000 vehicles a day travel through this aquaduct, which is the only connection between the 3 largest cities in the Netherlands. Man this thing should have been eliminated in 1985.

LOL

I wanted to post that image too, but you were faster.
I drove there last month... And I was amazed by the fact that less than 5 kms further the A-4 has 4 lanes and even 5!

OTOH, if people know it's a dangerous spot, I'd expect them to be extra cautious. There's a roundabout in my city with accident almost every day (usually locals are involved) and some people still learn nothing out of it.
