That is not to say there is no foreign involvement in the Dutch road construction sector. Many contractors hire skilled labor from the eastern EU. Some components are also built in other countries (in particular steel components which are often built in Belgium). But the leading construction companies are almost always Dutch due to their expertise with Dutch requirements. There is high demand for complex planning to speed up large projects while keeping traffic impact to an absolute minimum. In the Netherlands, only 3% of traffic congestion is due to roadworks. In Nordrhein-Westfalen, with a similar area, population and motorway network size, it is 50%.
Wouldn't you say that it is also a result of the tendering environment?

The tendering in the Netherlands is almost exclusively dialogue process, while in Poland it is two stage, price criterium tendering.

I am quite sceptical that dialogue tendering allows for much transparency as the price tendering does, and it is easy to split the market or arrange projects beforehand to fit the contractors in a dialogue tendering. Also I don't think that there happens much in the terms of price competition. On the other side, it allows for unique and smart solutions and it may allow for more flexibility.

Those dashed road stripes on the road side are sick. How many people end up in the grass because the think there should be a driving lane (in the dark for example). Seems to be very unsafe.

Dutch projects are not focused on price alone. In fact, some tenders have a more or less fixed budget with a contractor being able to fulfill 'wish list' options for a project.

Some projects, for example the A1/A28 Hoevelaken interchange reconstruction and widening project, the contractor who can build the most wishlist options within the budget gets the job.

These wishlist options are not the road design itself (number of lanes, configuration), but rather smaller auxiliary things as bike tunnels, overpasses, type of noise barriers, landscaping, etc. Things that are 'nice to have' but not an absolute necessity. These 'nice to have' things are often paid for by municipalities.

So they start a base project (expansion to x lanes and reconstruction in x configuration), with additional options being up for grabs.

For the N7 Groningen project there were three such 'wish list' items. The winning consortium included all three of them:
  • an additional bicycle tunnel under the railway, next to the road tunnel under this same railway.
  • one of the road exits was planned as one-way (only to and from the west), now it will be a full interchange.
  • the main Julianaplein interchange (N7/A28) will become more 'green' (i.e. more grass and trees rather than only concrete)
In addition to these 'wishlist' items the winning consortium had submitted a few 'innovative ideas', i.e. changes to the plan that they would like to see. Two of them were granted: another additional bicycle tunnel, and "improved design" of five bridges (I'm not sure what this means in practice).

That must be interesting getting e.g. the environmental evaluation or permits for these projects if they are that flexible.

And the wishlist is part of the dialogue right? I mean, it's not like that they send one envelope only. The whole tendering should be a dialogue process where the project is constantly being adjusted in several rounds if I understand it correctly.

If you can't see the difference between a driving lane and a grassy curb, you need either to buy new glasses or stop drinking.

but what about people who actually have been drinking and quite a lot? If they crash into someone else for example it is still a problem for society...

That's what the justice system is for. You can't safety-design your nation's entire infrastructure for the 1 in 1 million drivers who are dumb enough to drink and drive.

Exactly, while a better road design and signage can drastically improve safety, no road can be 100% idiot-proof. People still manage to enter motorways wrong-way despite all the signage.

Gereke has a point though, it's counter-intuitive to have dashed lines on the edge of the road. Dashed lines would usually mean you can cross them, but that's not the case here.

Some other countries also use it (France, Sweden), but those tend to be lower class roads. N279 is a major road designed for 100 km/h and full control of access.

A4 Benelux Tunnel

50 years ago the Benelux Tunnel of A4 on the west side of Rotterdam opened to traffic. Even today it is the westernmost river crossing at Rotterdam.

Back in 1967 they already had coin machines for payment, 1 NLG for a passenger car and 2.5 NLG (which was a coin known as Rijksdaalder) for trucks. Change and multi-axle vehicles had to use the manual lanes on the right.

Unfortunately the section immediately North of it wasn't completed until 2015, and who knows if they ever build the section immediately South...

Yes, but as part of the Rotterdam Ring Road it was not an underutilized tunnel, in fact they expanded the tunnel with more tubes in the early 2000s. There are now 5 tubes (4 tubes and a always out of service reversible tube).

It carried 130,000 vehicles per day even before A4 Delft - Schiedam opened to traffic.

Research studies on public tendering suggest that a tender focussed on price only, is very likely to perform worse in complex situations (which large infrastructure projects are) compared against tenders with room for negotiations.

That reminds me of the Italian A12 (the southernmost one, there's another A12 more north): Rome-Civitavecchia opened in 1967, Civitavecchia-Tarquinia in 2015. That's OT, though.

N7: Have construction works been started?

It's one of the most expensive (per km) projects in the Netherlands, with a budget of € 666 million to upgrade a 4 km stretch of N7 to a fully controlled-access expressway with up to eight lanes. However, the main contract came in much lower at € 388 million.
===========================

N23: What does "new expressway, mostly with four lanes" mean? Is it relevant for my expressway u/c list?

===========================

N35: Is the expressway section already u/c? What's the exact lengths?

The N35 will be widened to a 2x2 expressway with a 100 km/h speed limit. It will be partially built over the existing road, and partially on a new alignment around the village of Wijthmen. A controlled-access interchange will be built at Wijthmen, there will be no other access except for either end of the project.

Construction is planned to begin sometime 2017 and is planned to be completed by late 2018.
===========================

N62: Have construction works been started?

===========================

N434: Has the exact schedule been published?

The contract involves the construction of a four lane expressway between A4 and A44. The project is mostly underground, it includes a 2520 meter long bored tunnel.

The contract has been awarded to a consortium known as 'Comol5', which consists of Mobilis, Croonwolter&dros, VINCI Construction Grands Projets and DEME Infra Marine Contractors.

Construction is scheduled to begin this year and will be completed by late 2022. A more exact schedule will be released soon.

Also construction has started on several sections that are part of the N7 reconstruction project contract, but not part of the N7 as such. For example, construction has started on the Helperzoomtunnel under the railway (which is needed because the curent level railway crossing next to the N7 ringroad will be abolished), and also on additional A7 motorway exits at Hoogkerk specifically for buses (so bus routes will be faster and during the N7 construction hopefully more people will use buses instead of cars.

Next week the first relatively large road closure because of the project will start: the N7 exit number 37a (Oosterpoort) will be closed. This is permanent: it will not open again before the reconstruction, and after reconstruction both exits 37 (Helpman) and 37a will not return.
