Btw, I don't see the reason why to build R52 from Brno via Pohořelice. Some expressway from D2 via Břeclav to Austrian border might be so cheaper than to build "long" expressway from Brno. It might be just a few km longer way. Anyway, it is a bit late now.

The roadworks are finished. You can see the new pavement in the video. You merge from D1 around 3:10. The road is called Vídeňská radiála. (Wienna's radial road)

My oppinion is that as for now is needed only half or full profile by pass of Mikulov and refurbishment of the rest of the road I 52 to fully separeted level interchanges in full profile, the rest can stay half profile. The intensities would suggest half profile for the full lenght of the road anyway.

Interesting visualization of the D3 section Hodějovice – Třebonín. That is south of České budějovice. On the map, around here: http://www.mapy.cz/#[email protected][email protected]=6

In detail:

I thought the southern section was to be constructed as R3?

Well, I like D3 better anyway. I don't like main routes changing road numbers or prefixes all the time. Imagine the mess if German A3 was B3 from time to time for technical reasons.

It is not so clear to me, so far I know that the last border section should be still R3, basically where this video ends should the road go on as R3. Thats also what they say in the visualisation. This may however change in the future.

I agree on the R versus D mess.

Yes, I completely agree with you guys! I think the best solution would be if the last section Třebonín-border with Austria would be built as D3 like the rest of the motorway, the same with R11... And the renumbering of R52 from Brno to Vienna to D (the current section has motorway parametres - 26,5m wide, completely flat terrain,...). But it's always less mess than in Austria - A7 and S10...

It's also only a few countries which use the motorway-expressway system so extensive as CZ, PL, SK and A. In other countries the expressways do not form a real network, but only complement the main motorway network in less important areas. It's confusing if A) road numbers change all the time for no apparent reason and B) if the roads look almost exactly the same to the non-educated eye (i.e. the average motorist).

I think the best option is to rename R to D, because basicly there's no reason not to call Czech R the motorway. If I'm not mistaken Czech transportation ministry plans something like that, most R wil become D than and Czech motorway network will double in a day.
There's no reason to built sections near border with profuse parameters since traffic is there always very low.

Well, I don't know nothing about renumbering of Czech R to D but it would make sense, at least on some most important R like R6, R10, R35, R48, R49, R52 and R55. Maybe one day...

There was some article about it some year ago, they say at least 200 km of expressways should be re-marked as motorways at the first phase

It's something what Irish have done with their HQDC.

Somehow I dont believe this would happen before having finished the whole network, certainly not in the next 15 years. It would require rather substantial legislative changes, it would be also rather complicated with some old expressways as parts of them are certainly not of motorway standard. I mean, the change could be too expensive to happen.

That's what they say, expressway sections which will meet 160 kmph speed limit would be marked as motorways. That's some 200 km of current expressways at the first phase.
Currently expressways look like standard roads on maps although they are often better than motorways somewhere in western europe. The goal is to have one standard. Though I agree it's not the hot topic right now.

Interesting map of the animals migration corridors. The red dots are critical crossings with motorways and higways, yellow then important crossings. This map should give an idea about the need for ecoducts, etc. Bit late (when many stands already), but better than never.

Historic question!

An acquaintance of mine from Texas managed to get his hands on a 1941 Nazi road map. It shows a motorway under construction that would run from Liberec towards the southwest. I can see Road I/13 is partially a 2x2 road just west of Liberec. Does anyone know more about it?

See the image below; check the original size at Flickr

I have nothing substantive to say, but this map is an incredible find!

It's a plan of so called Sudetenautobahn. The construction started in 1939 near Eger (Cheb) in western Bohemia and some minor works were carried out also near Reichenberg (Liberec). It was suppossed to connect newly acquired cities in Sudetenland to growing net of Reichsautobahnen. In it's coverage were cities like Falkenau (Sokolov), Carlsbad (Karlovy Vary), Komotau (Chomutov), Brüx (Most), Bilin (Bilina), Leitmeritz (Litoměřice) and already mentioned "capital" of Sudetenland Reichenau (Liberec). Near Reichenau a tunnel was (alternatively) planned to cross the Jeschken (Ještěd) ridge. Here the whole route turned in the north direction to connect to Zittau, Görlitz and of course Berlin.

The original routing near Cheb is still clearly visible on Aerial Maps as a discontinuous line of trees (see link)

The remnants near Liberec are not distinguishable, current route of primary road Nr. 13 has nothing to do with it
