Not that I know, no. As ChrisZwolle menitoned, shipping lanes are always kept open so it's impossible to create ice roads that cross shipping lanes.

The whole Baltic Sea freezes in very very rare occasions, virtually never.

Ok, thanks. I thought you could cut it from Helsinki to Stockholm.

How anyone can get caught by these obvious speed cameras is beyond me. But apparently people do!

It never get frozen? That's weird as it is quite small river tho. The Danube/Dunaj was frozen for the last time in 1963 -

That is one of the reasons. Another one is that the ice on the open sea is far from being an even surface. Due to the winds and the changes in the sea level, the ice moves constantly, and there may be cracks between the slabs. The winds can cause a formation of huge heaps of ice slabs several meters in height. That is why the ice roads usually exist only in the archipelago where the ice is more predictable.



The longest official ice road in Finland is on the road 816, connecting the island of Hailuoto to the mainland. The length of the ice leg is about 9 kilometres and it is under a constant surveillance. The ice road is for passenger cars only. The heavy loads are carried by the ferry, which actually is an ice breaker.

Yes, two Hummers fell into Lake Balaton as the ice broke under them (such a Hummer weighs around 3 t)...

Is it possible to cross Lake Balaton by car/foot during hard winters when the water freezes? I see those 2 hummers that fell into water but I keep my question.

By foot, yes, it's very often possible. By car: dangerous, the ice is seldom thick enough to hold a car.

Lake Balaton is quite warm, it takes a while to cool and freeze I suppose.

haven't you said that Ljubljanica got frozen last winter, or 2 winters ago? i am sure that you wrote it at forum, so i remembered it as miracle.

I guess part of the problem is that Ljubljanica (like most other streams on Ljubljana marshes) is heavily regulated and it doesn't meander any more. But it's still quite slow and small, so my lay knowledge is not enough to explain this. Internet says it froze in winter 1829/30, partly also in Feb 1876 and in Feb 1858 (at the same time it was possible to cross Sava on foot near Čatež at Slo-Croatian border).

No, definitely not, I don't know what you remember. Looks like the last time it froze was in 1940, but only partly and only because they dumped a lot of snow in it there. Otherwise it froze in 1929 (page 3) when it was -20.6°C. It was under -20°C also in 1985, but it didn't freeze.

None of these cases happened on those few official ice roads.

AFAIK you are wrong. The reason you think it is warm is in fact that it is too shallow - that's why in summer it warms quite faster by the sun light and the temperature of the air above it. And the water feels nicely warm (for swimming etc.). But for the same reason the water in it should also get colder easily.
The above pictures with the Hummers also show how shallow the lake is, because most probably they have reached the bottom of the lake and that's why they sink no more and remain partly over the surface.

yeah, the Balaton is 3-4 m deep in average, the deepest point is 11 m. This "accident" happened about 30 m from the shore, where the water was about 1 m deep.
