All along the motorway these things are mounted on the crash barrier between the lanes. There's one crash barrier for each direction of traffic and only one of them has these things mounted.

There's a couple of different colors, the darker ones fewer, no idea if that is on purpose or coincidence. There's some with white and red stripes at regular intervals.

I can't figure the purpose of these, does anyone know?

Anti glare screen system to hide traffic beams from the other side of the road

Oh, that's the purpose? I don't think I'd ever guessed. Thank you.

Wish we had that in Germany. As great as the autobahn is, when it rains it reflects so much that you don't see the Markings anymore without highbeams.

But maybe that's a northern thing.

But looking at the picture there is no road behind them, only the path going up the mountain?

There's two opposing lanes of traffic on the other side if the barrier, I assure you. Cyprus drives on the left side of the road.

Looks like road going up the hill to the right.

Did you know: Open bottom crash barriers decapitate motorcyclists when they crash

👍

Now imagine crash barriers made of steel wire. I don't know if they are still used in new projects, but there plenty of them around and a reason they were called cheese slicers.

Edit: I had to look it up and it seems these barriers are being or have been removed: https://www.femamotorcycling.eu/wire-rope-barriers-removed/

They’re common in Australia. One of the reasons that motorcyclists are called “temporary Australians” and “meat crayons”.

Ow. That kind of hurts, even if I don't drive a motorcycle these days

they knew the risks when they bought those death traps

I would have guess to prevent animals from jumping it and wandering in traffic. The markers on the road side are just reflectors for night driving. This is speculation.

[–] steb@discuss.tchncs.de 3 points 1 year ago

That would only be effective for blocking access to the lanes in the other direction, these are mounted in the middle of the motorway, not at the edges. But I think the high beam shield is perfectly reasonable as explanation.

Doubtful, why just shield one direction of traffic if so?
