A4 Halsteren - Dinteloord picture-update

People are working everywhere on the 13 km stretch now!

For all pics (197 photos!) you can click here (there's some Dutch text under some pics, I don't know if it's translated into English very welll and the pics are NOT in chronological order!)

A 'short' summary. I've added location in the form of Google Maps links, this should make it more clear

Cycling bridge at Klutsdorp seen from exit Tholen


The trucks with sand for the slope of the cycling bridge were coming at a high pace. 2 trucks were waiting


Start of the parallel road that, in the future, will go all the way to the Drielindekensweg


Temporary cyclepath near Klutsdorp (which cuts through the construction site). Looking towards Bergen op Zoom with the cycling bridge nicely visible:


A look in the other direction (towards Rotterdam)


Near the junctionZoekweg/Stierenweg. Looking towards Bergen op Zoom:


And towards Rotterdam


Westlandse Langeweg. Looking towards Rotterdam (stupid sand everywhere! )


Looking towards BoZ


The future bridge in the Westlandse Langeweg over the A4 will be very narrow!


Alongside the Drielindekensweg. Construction has finally commenced here (this was the section they started working last).


Drielindekensdijk: looking towards BoZ


And now towards Rotterdam with the future exit Steenbergen in the background


Future exit Steenbergen, N257: The road is being moved a bit south to create space for the exit (This pic lacks focus )


Looking in the direction of Noord-Brabant's first aqueduct:


Pillars have been placed where the N257 will go over the A4:


Zoom.


Aqueduct Steenbergen. North side: Pics taken from the freely accessible viewpoint (which looks and feels quite unstable btw)


South side:


N259 just north of Steenbergen where the N259 will go over the A4. Asphalt! (Looking towards Rotterdam)


And towards Bergen op Zoom


Bridge over the Steenbergsche Vliet (as seen from the east)


Small tunnel in the Zuidzeedijk (also see video at bottom of this post). Looking from the west:


Just north of the Zuidzeedijk (looking towards BoZ)


From exit Dinteloord a lot of zoom in southern direction (towards Bergen op Zoom):


Viaduct over the A4 (currently numbered as A29) near Dinteloord:


To the northwest of the exit:


The picture above shows the exit coming from Rotterdam, as does the one below


The highway needs to be widened a bit here to make room for an exiting lane towards Dinteloord


Looking south from the viaduct Blauwe Hoef near Dinteloord


Video of the new tunnel at the Zuidzeedijk. (I recommend turning down the volume!)

MTM - Motorway Traffic Management

Motorway Traffic Management or MTM was introduced in the Netherlands in the 1970s to improve traffic safety. Gantries are placed across the roadway to signal information to motorists. The system mostly consists of speed limit reductions and lane closure indications. VMS's provide additional information.

The system works with AID or Automatic Incident Detection. Recently hailed in Texas as a new "high tech solution", it's been common along Dutch roadways for the last 40 years. The entire system is autonomous and computer controlled, requiring no human intervention. Of course traffic operators can intervene, for example to close lanes. But traffic jam and incident detection is entirely automatic.

A28 Soesterberg-2 by Chriszwolle, on Flickr

Some statistics:

* 16830 induction loops
* 243 radar detectors
* 14196 matrix signs
* 2618 kilometer roadway equipped with MTM (over half the network)
* 6 traffic operation centers
* 347 kilometers of shoulder running

A13 Kleinpolderplein interchange, Rotterdam

A car crashed off the highest flyover of the Kleinpolderplein motorway interchange. The driver was killed. According to local media, the speedometer was stuck at 170 km/h. The actual speed limit is 80 km/h. The barrier in question is a mix of a concrete jersey and a railing on top of it.

170 on that flyover is plain suicidal. Makes you wonder if the throttle was jammed...

My guess would be drinking and driving, since it happened early in the morning. And yeah, those Mini Coopers (it is one right?) are actually pretty fast.

The crashed car appears to be a high-end Mercedes. It looks like he did a Peter Pan off the ramp in Dukes of Hazzard-style.

Is this "throttle jamming" thing for real? You can brake a car even if it the throttle is pressed. The mechanical power of the brakes to at least seriously reduce its speed is much more than the ability of the axis to overcome the braking discs.

Some more pics of it, quite bizarre:

I wonder what caused him to launch above the concrete barrier.
The speedo could have gone to 170 due to the impact, however, to fly that far he'd definitely need a speed of 150ish km/h.

Having driven this flyover 100s of times, at 170kph I think it would have been a wonder if her hadn't gone over the top

I wouldn't rule out suicide

Same, but that corner is doable at 110-115 km/h while staying in lane, faster if there's no traffic and you use all available space ( outside>inside>outside), the barrier should have glided him along the edge unless he was doing well over 170 and toppled him over due to the impact...

Either that or he steered deliberately into the barrier. I believe that at 170 km/h, if he was steering in the correct direction, the barrier would not have send him flying over it...

It's not just the speed, it's also the angle of impact with the barrier. That's impossible to determine from these photos. Are there any CCTV cameras on that location?

In an average car, at 110-115 you'd be really pushing to stay in your lane. At 120 you'd almost certainly hit the wall unless you use the entire road space including the shoulder.
At 170 I reckon the impact with the wall would have been nearly instantaneous upon entering the curve.

I did it in a lowered car with soft tyres ( fwd tho)... I reckon the average rwd car (like the crashed Mercedes) can easily go faster too...

Doing 170 into a 80km curve is going to cause you grief what ever you're driving

That I agree, but at 170 I still think it shouldn't have launched him over the barrier but steered the car alongside it... Just a guess though of course .
