Some countries manage to maintain them while they can't afford to correct 30-years-out-of-date signs. Perhaps they can't afford to correct 30-years-out-of-date signs because they're spending their money on matrix signs.

They don't. Problem is just an enourmous budget-cut.

Next problem will be much more tailback-injuries at traffic jams, for example on A7 Purmerend-Hoorn, a dead straight, on rush hours very busy motorway.

A15 Rotterdam

I went to Rotterdam last Sunday to pay a visit to the construction site of A15.

The A15 is currently a 2x3 motorway. It will be widened to 10 lanes, with 12 - 14 lanes near major interchanges. A much-needed makeover of this important transportation corridor.

1. Interchange Vaanplein. This may be the third most impressive interchange of the Netherlands. The major downside is that it lacks the symmetry of the Ridderkerk and Prins Clausplein Interchanges.

2. The A15 is an a-symmetrical widening, because the Betuwe Freight Railway lies to the north, the widening will be chiefly on the southern side of A15. Luckily space has always been reserved for this. A large embankment acts as a noise barrier to Barendrecht, which is turned into a nice park.

3. The new motorway will be twice as wide at this point, from 6 to 12 lanes.

4. A new flyover under construction at the Vaanplein interchange (A15/A29).

5. You don't see widenings of this magnitude very often. 5 - 10 years ago something like this was unthinkable, in an age where the best widening was a shoulder turned into a peak hour lane.

6. This is a temporary setup. When finished, the express lanes will feature 4 lanes at this point, and three lanes on the local lanes, of which 2 will go towards A29 south and 1 towards the Rotterdam-IJsselmonde exit.

7. This is also temporary. This will act as the A15 motorway in the near future, when the old carriageway will be rebuilt. The end situation will feature two parallel carriageways for eastbound traffic with 7 lanes.

8. The new Portland noise barrier is visible in the distance. This is one of the tallest noise barriers in the Netherlands.

Heck, it may be one of the highest elevations in the Netherlands. [joking]

Meanwhile all those jokes about low-lying NL have put the Danes to sleep. NL has extensive coastal defenses but the Danes have a much flatter country (highest point NL 320m, DE 170m) and no defenses. When the ice caps do melt, it won't be the Dutch who drown first.

We should start telling jokes about the Danes so they wake up to their predicament.

I bet the Danish average altitude is substantially higher than the Netherlands. The highest point in the Netherlands may be higher, but much more land area is below +5 m in the Netherlands than Denmark.

And the thing is that most of us Dutchies decided to get cozy in the lowest part of the country.

I allways wonder if I would manage to escape to Germany to get to some high ground.... I have some ideas about the best escape route, I would certainly not take a motorway.

Great map btw.

Well, I have seen a model, in where Amersfoort is changing its name to Amersfoort-on-Sea, and where the capital and seats of parliament is now in Maastricht. In the mean time I will be high and dry in Mayrhofen (640 metres) and if that is not high enough, we can wander up to 3500 metres in this area. I won't get wet feet in a hurry...

Using this link http://www.dr.dk/Tema/vandetstiger/index.htmcan give you an idea of altitudes in Denmark (the map is meant to indicate problems of rising sealevel). Low lying areas along the south-west coast of Jutland and southern Lolland are protected by dykes as in the Netherlands

Yes but the beach and the sea would be highly toxic because all the chemical industry, other industry, oil refineries and nuclear power plants would have been hit.

Not exactly a Caribbean dream.

Surely it wouldn't happen so fast you need to worry about the fastest route....

The main issue in the Netherlands is that a couple of million people are only protected by one line of defense; the "dike ring 14". Because most of the infrastructure is below sea level, it will make transportation impossible very quickly. Dike ring 14 has some weak spots which will be reinforced in the coming years.

Storm, breach, tidal wave. How long does that take? Those hurricane evacuations in the US look pretty traffic jam prone to me. Imagine evacuating dike ring 14 in the space of a few hours. I dread the mere thought.

Well, I was thinking a permanent rise in sea levels - the type that would require the permanent abandonment of the Randstad - would take years rather than resulting from one storm, so people would gradually move away as the writing on the wall became clear.

If, however, a dike breach or whatever is more likely during the process, I suppose you have a point: it could be sudden.

Because the Sea protections are so high, a small sea height increase is actually less damaging to Netherlands than it would be to, say, Germany or SE England or Florida.

The funny thing about this maps is that the high contrast colors give the impression there are some low Alps just north or Arnhem and ski station-country between Maastricht and Heerlen
