How is it called that landing strip between left lane and guardrail?

The paved area left of the solid road marking is called a "redresseerstrook" in Dutch. I haven't heard a good English term for it yet, it's too narrow to be called a left shoulder. Its job is to retain traffic on the pavement, so I guess it could be called a retention strip. They used to be wider in the 1970s than they are today, likely because they think wide roads cause people to speed, that is why you'll never see even narrow shoulders along non-motorways.

Nice
I think it is commonly called "left shoulder" even if it's clearly not wide enough to safely accomodate a vehicle.

I think it's a useful feature, as an emergency manoeuvre space; that's why I asked why they won't pave it (as in the posted picture). Maybe they think people could try to drive and overtake over there?

That strip is completely missing in the Italian system... in some cases we have the guardrail directly over the solid marking

The guidelines usually prescribe a full-width left shoulder if there are 4 or more lanes in one direction. However, it's not implemented often due to high cost, and not rarely are they changed to driving lanes over time. An exception is A2 Utrecht - Amsterdam which is wide enough to support 2x6 lanes and still maintain a left shoulder without having to physically widen anything.

A retention strip is usually between 0.60 and 1.10 meters wide.

The median is not paved over for practical reasons, such as rainwater runoff, and more importantly, the snow removal process. Snow plowed to the median can melt without creating excessive runoff across the driving lanes.

If is in fact simply a hard strip. That a look in the DRMB if you don't know the English terms.

A flyover has been constructed across the "24 Oktoberplein" (24 October Square) in Utrecht. It opened last week, I filmed it today.



I have a new camera by the way, which produces much more stable footage.

A73 Neerbosch Interchange

The Neerbosch Interchange is a trumpet interchange along A73 west of Nijmegen. It connects unsigned spur Rijksweg 783 with A73. The A73 runs in a "TOTSO" where you have to turn off to follow A73. Worse, the connectors have only one lane. They are currently widening the connector from west to south to two lanes.

A4 De Hoek - Burgerveen

The left shoulder running along A4 between interchanges De Hoek (A5) and Burgerveen (A44) south of Amsterdam ceases as of today. The left shoulder - which was built as a regular lane in 1999 and 2003 - is now a permanent lane. The speed limit should be 120 or 130 km/h (not verified yet in the field). This means there are now 2x5 lanes, 24/7, with no speed limit reduction.

The layout of A4.

Thanks for the regular updates ChrisZwolle! Could you help to explain what is the logic for plus lanes, why aren't they built as regular expansions when constructed?
Shoulder running looks like a quick and cheap way to increase capacity. But those plus lanes are always on the left of the existing road and actually widen the road. To me it looks a bit silly to build them as lanes which are only used in high traffic and then open them permanently only a couple of years later.

It used to be faster to realize than a regular widening, because plus lanes required less procedures, just like shoulder running lanes btw, but with plus lanes you keep the shoulder. So to get traffic flowing quick, the government often chose for plus lanes in stead of a full lane, purely for procedure times.

The A4 near Hoofddorp was a different story. To get the extra fifth lane, 2 other left lanes had to be narrowed for it to fit. The fact that the lanes were more narrow made the most left lane a plus lane.

However, plus lanes are not faster in procedures anymore, hence no new plus lanes/shoulder running lanes being built/planned

See this post for more info about the unique "plus lanes".

That's not entirely correct. The A28 is currently under construction at Amersfoort and includes plus lanes. Also A15 in Europoort includes plus lanes. Furthermore, the widened A27 north of Utrecht will include shoulder running. In addition, shoulder running is planned on A1 Bunschoten <-> Hoevelaken and A7 Purmerend > Zaandam.

Building halftime lanes to speed up procedures seems a silly reason to me (although I'm sure you're right).

It's always bad when bureaucracy overwhelms practicality...

There was a time when even Dutch roads could be in very bad condition. The location of this photo is unknown to me. It was taken in 1979.
