I still think that the other option with the half Haarlemmermeer and a roundabout is much saver due to the left driving trucks in this chosen interchange.

A9, Badhoevedorp

Two stages of the A9 bypass of Badhoevedorp opened to traffic this weekend.

On 16 December, the connector from A9 (Haarlem) to A4 (Schiphol) opened to traffic.

On 17 December, the main carriageway for eastbound traffic of A9 from Haarlem to Amstelveen opened to traffic. It is the first main segment of the reconstructed Badhoevedorp interchange to open to traffic.

Road authority Rijkswaterstaat compiled a list of tunnels closed most frequently due to overheight trucks.

Number of closures in 2015:
* Velsen Tunnel (A22): 8677
* Coen Tunnel (A10): 1249
* Drecht Tunnel (A16): 438
* Zeeburg Tunnel (A10): 326
* Swalmen Tunnel (A73): 146

There are 18 tunnels in the national road network, another six are planned or under construction. The clearance varies by tunnel. Newer tunnels are built with a 4.7 m clearance so they don't need any type of detection for overheight trucks.

speed limits

The speed limits go up on several stretches of motorway.

* A2 Leenderheide - Budel: from 120 to 130 km/h
* A7 Tijnje - Drachten: from 120/130 to 130 km/h
* A12 Gouwe - Reeuwijk: from 120/130 to 130 km/h
* A15 Meteren - Valburg: from 120/130 to 130 km/h
* A28 Den Dolder - Maarn: from 120/130 to 130 km/h

In most of these cases, the difference between 120 (day) and 130 km/h (night) is eliminated, allowing 130 km/h at all times.

In case of A7 this creates a long stretch with a 130 km/h speed limit from Sneek to Groningen, except for the Joure roundabout (70 km/h until the replacement interchange is finished in 2017) and at the Drachten cloverleaf (100 km/h).

A2 Leenderheide - Budel and A15 Tiel-West - Echteld will be raised in 2018 as rehabilitation is planned first.

According to reports, the other stretches have been raised to 130 km/h this week.

Are there detailed reports on pollution and accidents on these stretches with higher speed limits?

Yes, safety, noise and other environmental aspects are mapped for every speed limit raise. The environmental impact is extremely small (in the order of 0.1 - 0.3 dB or < 1 g/m). On many stretches air quality has improved despite speed limit raises.

The calculated impact is mostly a theoretical issue, as the speed of traffic varies and it's mostly a legalization of speeds already driven, so the air quality or noise levels changes are so small they're only theoretical.

Sorry, does it really mean that this tunnel was closed 24 times a day because of overheight trucks? It sounds crazy. Once in every 2 hours in each directions. OK that's an old tunnel and has a lower clearance than the modern ones (according to this sign it must be 4.0m) but even so.
Or could you interprete what those figures exactly mean?

When an overheight truck is detected, it is first warned by signs to take the exit. If the trucker proceeds anyway, traffic is stopped and the barries close. The truck is then taken off the motorway and measured. If it is too high, a € 700 - 900 fine is issued. A typical tunnel closure lasts 10 - 20 minutes.

The Velsen Tunnel was a problem because it is the oldest motorway tunnel in the Netherlands (1957), with a very small margin compared to newer tunnels.

The tunnel is currently closed for renovation, it will reopen next month with a better clearance, so the number of closures is expected to go way down. It also won't require any major renovation until 2045.

What is the maximum allowed height for road vehicles (trucks but also buses) in the Netherlands?

4 meters.

The Velsen Tunnel has a clearance of only slightly more than that. A problem is that detection can go off for various reasons, such as an empty truck with a raised suspension, an uneven truck (slightly tilted trailer) or a tarp on the roof that dangles by the wind.

Most offenders are foreign truckers. The Tata Steel plant in IJmuiden is served by the Velsen Tunnel, so it handles truck loads from many places in Europe.

The Velsen tunnel also gives access to the largest industrial facility in the Netherlands, the Tata Steel IJmuiden plant.

That's interesting

For comparison, how fast would one need to drive (say on A2 around Breukelen) to get 900 EUR fine from a flitser?

I dont think fines go that high for speed alone. They say roughly 10€/km for speeding. If you drive 90km/h to fast you lose your licence anyway and would more likely get a judicinal punishment.

Anything above 40km/h too fast on the highway goes through court, if you have a bad past then it's not unlikely to get a large fine like this. However if it's your first large fine then it's not gonna be this expensive at all, no.

A22 Velsen Tunnel

Rijkswaterstaat announced that the Velsen Tunnel will reopen to traffic on 16 January after a 9 month closure.

During the renovation works, they stripped the entire tunnel, applied new pavement, a new ventilation system, new escape routes and - importantly - an increased clearance of 12 centimeters, which is expected to significantly reduce the amount of tunnel closures as discussed in the previous posts.

Although the tunnel will reopen on 16 January, some traffic restrictions remain in place. The final paving outside of the tunnel will have to wait until the spring, so there will be a 90 km/h workzone speed limit until then. The reopening of the tunnel could be postponed if severe winter weather would occur.

Ah yes. So if you drive 190 km/h harmlessly on motorway (as is custom in neighboring countries) you go to jail
But if you drive an oversized truck past barriers and into a tunnel potentially killing people, 900 Euro oh well...

No one goes to jail just for speeding.
And 190 km/h is not customary in the neighbouring countries (even in Germany driving at 150 kph will generally put you in the higher speed range).

Driving 190 km/h in the Netherlands is dangerous. Even if you have full control as a driver, other drivers will likely misjudge your speed because traffic generally moves in the 80-130 km/h range.

I would have no problem driving 190km/h on the nearby A4 during the night. Pretty much deserted anyways. But I wont do it because I like my drivers license too much

I think it's a misconception to think that a high speed is safer at night because there is less traffic.

It's much more difficult - if not outright impossible - to avoid wildlife or debris on the road with such a speed on an unlit motorway with light traffic. What if someone spun out, hit the crash barrier head on and then stopped on the left lane with both headlights damaged? There is no way you can see that far enough in advance with 190 km/h. The same goes for lost cargo, debris or wildlife. It would be a challenge even with 130 km/h.
