A7 Afsluitdijk

A study by the Central Planning Bureau found out that replacing the Lorentz sluices of the Afsluitdijk near Kornwerderzand is not economically feasible. The cost for a naviduct would be around € 200 million, but the relatively low traffic volume of 19.000 vehicles per day and the approximately 7.000 bridge openings per year do not pose a significant economic loss, valued at approximately € 13 million.

Because the sluices have a life-cycle until 2050, constructing a naviduct can only be feasible when the sluices need replacement. Which means there is a low chance the naviduct will be constructed within the next 35 or 40 years.

Lorentz Sluices:

What about a very high bridge? It's a dyke, not houses nearby, and the place is entirely man-made in the 1930s anyway...

If the lockers are to last until at least 2050, then don't worry about it right now. Don't these people know we have a crisis on?

The sluices need renovation/reinforcement in the coming years, but an entirely new system is not considered. Don't forget sea locks are extremely expensive. The new sea locks at IJmuiden are valued at € 848 million and a new sea lock at Terneuzen exceeds € 900 million. These Lorentz locks are smaller, but will likely still require a multi-hundred million investment.

Couldn't they replace both locks on the IJsselmeer by a single larger facility in the middle of it? (Like they've built the Neeltje Jans barrier).

Also, a related curiosity: how is the salinity of the IJsselmeer?

The IJsselmeer (Lake IJssel) is a freshwater lake. Water from the IJsselmeer goes into the Wadden Sea and not vice versa.

Isn't it dangerous to put lots of fresh water into sea water?

Um, don't most rivers do that?

Not that I know anything about, um, aqualogy (even the right word for it - just made that up!); I'm just sort of assuming....

Actually, the now-IJsselmeer was salt water before the Afsluitdijk was built, wasn't it?

In which sense dangerous? For the marine biological equilibre?

Yes, it was a sea gulf, so it was salt water.
But how they managed to turn it in freshwater?
And was it planned to be dried entirely?

Yes, it was the Zuider Sea, a part of the Atlantic Ocean. Places like Vollenhove, Volendam, Elburg & Kampen used to be seaside cities.

The southwestern part between Flevoland and North Holland (Markermeer or Lake Marken) was originally planned to be a polder like Flevoland. That's why the N302 is called the Houtribdijk (dyke) while it is in fact a dam. Same for Afsluitdijk (Enclosure Dyke) which is also a dam. On the other hand the dams of Zeeland province are actually called dams.

The Zuiderzee itself was created after a storm in 13th century IIRC. It used to be marshlands until a fierce storm penetrated further inland and washed away the marshland.

Coentunnel A10 Amsterdam ring road

The ventilation buildings of the old and the new Coentunnel (under the North Sea Canal) as seem from that waterway!

A4 Delft - Schiedam

The construction of the A4 between Delft and Schiedam becomes more visible.

A58 Eindhoven - Breda widening

The province of North-Brabant wants to pre-finance the widening of two segments of the A58 motorway; on the south side of Breda, and from Eindhoven to Tilburg. The A58 will be widened to 2x3 lanes. € 425 million has been reserved in the 2021 - 2023 period, but North-Brabant will loan the national government € 170 million to speed up the construction by 3 to 5 years. States-provincial will decide about the proposal in September, after which Rijkswaterstaat can begin procedures for the widening.

The A58 motorway carries 76.000 - 88.000 vehicles per day on 2x2 lanes. Strangely enough the Tilburg - Breda section is not included in the plans while it carries similar volumes.

Why? I've hardly ever got stuck in traffic there, apart from minimum delays on the intersection onto the A16 towards Antwerp.

traffic sucks over there. You've probably only been there in the right moments without traffic congestion...

I was probably sitting in traffic 20 mins prior on the A27 coming from Utrecht, before the upgrade. After making it past Meerkerk I only got jams at Antwerp to look forward to. I thought the Dutch were so keen to save money...

The fact that you drove there a couple of times and didn't get a traffic jam doesn't mean that there never is a traffic jam...

About 50% of the time we pass there we have a traffic jam. And we almost never drive there during rush hour...
