The Veluwemeer Aqueduct, also known as the Drontermeeraqueduct, is a unique structure in the Netherlands that carries a canal over a large lake.This impressive water bridge spans the Veluwemeer lake, connecting the provinces of Flevoland and Gelderland

It’s basically a very short tunnel when you think about it.

[-] EddoWagt@feddit.nl 16 points 1 year ago

Or a bridge for the water

[-] Mininux@sh.itjust.works 33 points 1 year ago

my brain took way too long to understand the picture

[-] phx@lemmy.ca 17 points 1 year ago

Anyone know what the depth of the water is above the crossing point?

That's about 10 meerkats for those wondering.

[-] Alchemy@lemmy.world 3 points 1 year ago

I was, thank you.

How many times the size of texas?

93 years to build! I should calm down about the local projects.

[-] MBM@lemmings.world 15 points 1 year ago

You don't really notice it when driving underneath, but standing at the top or sailing across such aqueducts is very weird

[-] sangriaferret@sh.itjust.works 12 points 1 year ago

Any reason this was more practical than building a bridge?

But it's only 3m deep. How long are keels on tall sailboats?

[-] smashboy@kbin.social 16 points 1 year ago* (last edited 1 year ago)

A lot of the sail ships used on inland waters here have flat bottoms, like for instance the skûtsje. So they can sail in quite shallow waters.

[edit] I’ve looked it up and for instance a tjalk (historic freight ship) can have a mast height of around 20-25 meters, but has a sailing depth of only 80-200 cm. Due to their flat bottoms, they can easily move around the inland lakes and canals, which are often only a few meters deep.

[-] gaael@lemmy.world 3 points 1 year ago

Most 10-meter-ish sailboats have less than 3 meters-deep keels, usually less than 2 meters.

[-] sangriaferret@sh.itjust.works 1 points 1 year ago

Ah, interesting. Thanks.

[-] Player2@sopuli.xyz 8 points 1 year ago

No height restriction for boats with masts perhaps

[-] Willy@sh.itjust.works 12 points 1 year ago
[-] smashboy@kbin.social 7 points 1 year ago

A lot of the larger boats on inland waters here have flat bottoms, and the smaller boats are just not that deep. So it’s sufficient for the typical boat traffic.

[-] espentan@lemmy.world 4 points 1 year ago

Exactly, I doubt you can sail a Panamax through that. Useless. /s

[-] Nouveau_Burnswick@lemmy.world 2 points 1 year ago

Tallest human was 272cm, so it is Humanmax!

[-] emergencyfood@sh.itjust.works 8 points 1 year ago

I don't get it. Is it a road bridge across the lake with an aquaduct above it? But then is the road above or below water level?

[-] agent_flounder@lemmy.one 18 points 1 year ago* (last edited 1 year ago)

This is the Netherlands, where swaths of the land is below sea level. So, naturally, this is a road below the water's surface with an aqueduct above it, enabling boaters to cross over the road. Or at least that's what I'm seeing here.

[-] emergencyfood@sh.itjust.works 3 points 1 year ago

Got it, thanks!

It's a road on a man-made land bridge before and after this aqueduct. In this shot here, it's a bit hard to see, but the road is actually on a slight angle to make more room for the aqueduct. The walls around the road are only for this section, as out of frame the road is almost certainly on top of your bog standard land bridge.
