I guess it would be much cheaper to remove part of the landslide than to dig or bore a tunnel.

Archaeological research is going on in some parts. There are still problems with a tiny piece of land that is not in ownership of the state.

The only tunnel that are some crazies talking about afaik is a long tunnel under the whole mountain instead of already build parts of the motorway, including the build bridges and two small tunnels . (i.e. the original alternative variant).

I don't know how they will solve the landslide. I am not a construction engineer. I would say they need to stabilize the slope. Make sure that the water that came due to the mine at the top of the mountain doesn't go inside this slope again. That's the most important.

They will maybe need to anchor that 200 - 400 meters of the motorway deep into the mountain bellow the sliding layer and build some gabions or some other walls at the hill side of the road. I don't know if some sort of "tunnel" cover would be useful there.

It is not that deep, and anyway, it would not be possible to dig a tunnel in the landslide soil. It would not make any sense imho.

In such a case, the most important consideration for the civil engineers is the angle of repose. If the slope is steeper than the angle of repose, then it needs to be restrained in some way, such as with a retaining wall or pilings. If the slope is shallower than the angle of repose, then it should be ok as is. Of course, there must be a conservative margin. Following a landslide, the slope is typically at or very near the angle of repose. Digging to reach the buried roadbed will increase the slope, so it's clear that something will have to be done to stabilize the soil.

I've read it includes D3 from Veselí nad Lužnicí to České Budějovice and an unspecified segment of R4. It also includes renovation of D1.

Czech Republic is getting prepared for it's first road closure on D1 motorway with temporary barriers and 2x2 traffic on one carriageway. We all know here that we are years behind our colleagues in Germany, Austria or other "western" european countries but it's still nice to see that we've entered the club finally .

This measure is bound with the so called modernisation of D1 motorway and takes place on 3 of 4 stretches being under reconstruction now. Driving lanes are 3,15 m and 2,5 m wide. Here are some pictures:

This list should determine the priorities. The government has to approve the the tendering for the projects if the price is above certain tag (CZK 300 mln). In march it approved following tenders for motorways, expressways and first class roads:

Section..................................Lenght............price tag without VAT (CZK)

D3 0309/II Ševětín – Borek.................10,6 km......1 706 933 600,00
D3 0309/I Bošilec – Ševětín................8,1 km........2 317 253 000,00
R4 Skalka - křižovatka II/118..............4,8 km........779 000 000,00
I/37 Pardubice – Trojice, II. etapa.......1 km...........591 389 400,00
I/44 Červenohorské sedlo – jih.............8 km..........448 644 900,00
I/38 Znojmo obchvat II......................3,5 km........355 280 000,00
I/68 Třanovice - Nebory.....................6 km...........2 143 285 100,00
I/34 Božejov – Ondřejov – Pelhřimov.....5,4 km........467 329 000,00

Total..............................................47,5 km.......8 809 115 000,00

http://www.mdcr.cz/cs/Media/Tiskove_...c_a_dalnic.htm

It can later on this year approve another projects as well.

There are multiple projects already undergoing tenders or the evaluation of the tender results. In many cases administrative reasons are preventing the construction to begin.

Namely these motorways and expressways:

D1 0137 Přerov – Lipník...................14,3 km
D3 Veselí n. Luž. – Bošilec................5,1 km
D3 Borek – Úsilné............................3,1 km
R55 5505 Otrokovice, JV obchvat.......3,1 km

Then you have projects that are long tendered but currently not under construction due to administrative problems:

D11 1105-2 Osičky – HK (část Praskačka – Hradec Králové)......4,4 km
R49 4901 Hulín – Fryšták....................................................17,3 km

I've travelled on saturday on D1 between Brno and Prague and the modernization works have restarted. However there were no traffic problems.

What is your impression of the sections completed last year in contrast to the sections yet to be done? Can you say anything specific, other than that the new sections are better? Any other impressions of the works?

I think there is no finished section yet, they just stopped the works for the winter and they restarted now. The works are complex, they will also add some new overpasses, rebuild some bridges and enlarge significantly the motorway (even if it will still be 2+2). Now the quality varies a lot, there are sections where you can drive decently and sections where the driving is very lousy and uncomfortable for cars and passengers. The construction sites are limited to 80km/h, but ussually the people drive faster, around 90-100km/h. I needed 1h 45 min between Brno (intersection with D2) and Prague (exit 1).

ORF reports that construction of R52 towards Vienna would begin soon.

http://noe.orf.at/news/stories/2639640/

Nachdem jahrelang die Finanzierung des Autobahnbaus auf tschechischer Seite unklar war, gibt es nun im neuen tschechischen Regierungsübereinkommen positive Signale für einen Ausbau.

No.

"könnte" = could (2x)
"positive Signale" = positive signals
"Kreishauptmann Südmährens werde sich für die Finanzierung des A5-Ausbaus auf tschechischer Seite stark machen" = Even the destrict administrator of South Moravian will agitate for funding of the A5 building in the Czech Republic

ORF reports that the construction could maybe possibly start in the future.

That would be a big surprise. R52 would be financed by RSD, not local government, right? So I'm not sure there's any more to this than wishful thinking.

The local governments are becoming somewhat more active. They try to lobby, and they even offer e.g. some participation in buying out the land. Officially though they don't have influence on the D,R and I roads construction, they might be willing to participate, especially with the I roads, also financially, to get things done.

There are huge administrative problems with R52 due to revoked exceptions allowing crossing the protected nature areas. Furthermore the spatial development plan of South Moravian region is one big mess. The only thing that might see start of the construction in the next few years is the Mikulov bypass.

just out of curiosity: wouldnt it be easier to connect to Austrian A5 via D2 at Hustopece or Podivin? or are there environmental issues?

There is at least the obvious environmental issue that a detour via Hustopece or Podivin would be a needlessly long route which would result in increased pollution for every vehicle traveling between Brno and Vienna.

There are two Unesco protected reserves south of D2 and north of Austrian border.
http://en.wikipedia.org/wiki/Lednice...ural_Landscape
http://en.wikipedia.org/wiki/P%C3%A1...Protected_Area

It would have been possible to make a connection perhaps by building a Břeclav bypass south of Břeclav, next to the railway. The Austrian side did not want that though. They wanted the A5 going to Poysdorf afaik. Neither Břeclav wanted there an expressway.

It would be just about 10 km longer (out of cca 85 km). I don't see that as "needlessly long route" especially as it would significantly reduce construction cost and land use.
