Isn't that acquaduct an overkill? N31 crosses that canal near an industrial zone that is not even part of "old" Harlingen. But, apparently, acquaducts are the new Fryslând windmills: popping everywhere.

Why building a trench in the difficult Dutch terrain, instead of a bypass in the fields outside the town?

Another question: does anyone have photos of the new landtunnel in Utrecht, maybe also showing the outside' Will it be covered by grass to make it resemble a hill?

A new alignment east of Harlingen was considered, however it would still need an aquaduct, as a high bridge is considered horizon pollution in the flat open spaces of Fryslân. Furthermore, the road needed to be longer than the original road, increasing cost, while the original road must've been retained anyway for traffic to and from Harlingen, thus the barrier the elevated road currently is, would remain. This is a better solution for both Harlingen and traffic interests.

If I understand it correct, they will depress the current track of N31 and widen it. Creating only one interchange for the city traffic. Having it run under the railway and the canal.

Do you have any visualisations? I would be curious about how do they plan to connect both parts of the city. Why dont they make it run in a tunnel altogether through the city? I would imagine that running it in a tunnel, not constructing aquaduct and enlarging the original bridge could be also a solution, and not much more expensive I would guess. But yes, opening the biridge would pose a problem. Thus aquaduct is better variant.

It would be interesting to know, whether the land above the tunnel could be sold to developers (or othewise rented etc.) to cover for the additional costs of building a tunnel and perhaps making a small profit compared to the no tunnel variant of it lowering the overall costs of the project.

I think that some real estate development is planned to finance part of the investment of the city. At least it looks like there are some new buildings in the visualizations.

There are several visualizations here: http://www.viadrupsteen.nl/gbo-n31/

This is one of them:

Thank you for the link. Nice visualisations. I think there could have been at least short tunnel made to make the city bit compact.

No need for that. Harlingen is already compact enough.

I made a little map of Fryslân (Friesland) province with all motorways and expressways to be completed by 2020. This map only includes 2x2 expressways with limited-access (grade-separation). In my opinion, Fryslân surely has the best road infrastructure of the Netherlands, considering the province has only 650 000 inhabitants.

Do you think will N31 sections be renamed to A31?

No, these sections won't meet motorway standards.

I would think that the aquaduct is mainly for the benefit of boats and not for the cars

it is also a benefit for cars: they don't have to wait for boats. Example: the bridge near the Volkeraksluizen opens approx. every 30-45 mins.

Yes, the Van Brienenoord Bridge at Rotterdam has issues with me:

We have that with the Haringvlietbridge, which is 3 kms north of the Volkeraksluizen which I mentioned. We have to wait there 80% of the time....... Could be worse: my neighbour drives there about once a week, an the last time he didn't have to wait was somewhere in october last year.

A15 Ressen - Zevenaar



Minister Schultz has formally chosen the bridge alternative for the extension of A15 from interchange Ressen to A12 near Zevenaar. There was a large amount of public input, with 1501 comments, out of which 443 were unique. The project will cost € 750 million, out of which € 282.5 million will be paid by tolls. The project is planned to be constructed between 2015 and 2018.

Below is an animation of the first leg of the Schiphol - Amsterdam - Almere megaproject, the widening of A10 and A1 to 2x4 lanes in the direct vicinity of Amsterdam.

And together with that the ground-level video
