What constitutes the 4.1? Tunnels?

Can someone tellme why the strech nr. 520 of the Prague R1 can't be built without the othr streches 518 and 519? I know there are problems with these 2 streches, but i think it is possible to build the 520 alone as it ends crossing with the D8. So we would have all motorways and expressways around Prague connected together, of course when the strech 511 is also built.

Because stretch 519 has two alternative endings on D8... If construction of any alternative will be approved (territiorial decision), then also 520 stretch would by finally localized.

Yes. Basically every tunnel in Czech republic has speed cameras measuring average speed of vehicules along its entire length. Even more the average speed traps are becoming increasingly common even on non tunnel stretches of many expressways and even roads especially in urban areas. So beware.

Luckily the locations of average speed measurements can be relatively easily identified as at its beginning and its end there is a thin short line across the lane (the very same as in the video) + speed cameras pointed at the line.

Exactly. D8-Prumyslova-Vysocanska is 2x2 without level crossings over its entire length, so for the time being it's a sufficient substitute for the missing part of The Prague Ring.

Judging from this map, I like the Northern variant. What are the main arguments against it?

Really? Because by all means it's nonsense:
  • 8 kms longer (20 vs 28), take into account that it should cover all transit routes on west-east axis,
  • direct costs are very similar to the southern one, but the northern one requires longer feeders and supportive road system
  • southern variant is stabilized sice 1930's, first in a cut, now with a long cut&cover tunnel through Suchdol
  • there is also a problem with protected area of nuclear research area near Řež
  • northern variant doesn't help as a connection between northern parts of the city
  • and many more....

Very complex summary in czech is here: http://www.okruhprahy.cz/forum/viewtopic.php?id=18

Ok ok, well I imagined which variant would be better for me, and that's selfish of course. The Northern variant would be slightly better for people from Neratovice, but I agree that its disadvantages disqualify it completely. And I think that even the NIMBY's in Suchdol will once be celebrating the highway in its Southern variant.

It's a pity that the terrain is so complicated so the costs will be high and long tunnels and high bridges are needed. But Prague won't have a problem with that, given the length of tunnels under the city.

I have a flat in suchdol and I can tell you that accoridng to the southern variant of the 518 i would be on the ringroad in 1 minute! I don't understand why so many people are agaisnt it, including my neighbours which made also a petition, that, of course, i didn't sign. For now the only chance to og on the other side of the river is going through full of traffic roads, so i am looking forward for the opening of the tunel Blanka complex!!

No, the name originates historically from a place where the cattle feeds.
"Tur domácí" is the biological name of cattle in Czech. But commonly you would not use it

Thank you for the information. Actually we have this word in Bulgarian( pronounced: "тур"=Tur~Tour or choose, am I wrong?). It means an extinct wild forest Еuropean bull and the chess figure-castle/rook.

Sorry for the off-topic. Maybe to return on-topic, could you, please, share the plans for future motorway developments of your new government?

I believe it's reffering to 'Tur' as to what it means in English : 'Aurochs'

Inliners on Prague Ring road

Section 513 of the Prague Ring R1 was opened for inliners today, there were also two races (10 and 21 kms), after that one half (left) was opened til evening for everybody (on 7 kms). Riding inline skates on brand new concrete surface was really amazing. Few photos:
