AFAIK only the bridge has been opened and you still have to cross the city: http://maps.google.cz/maps?saddr=1.+...sz=15&t=h&z=15 - the rest will follow next year.

A lot of fanfare for a little bridge opening then

Here's another video, R7 from Praha to Slaný, one of the worst quality expressways I've seen in the Czech Republic.

Yeah, R7 is pretty much substandard and won't fit to any motorway standards. The worst on this route is that it lacks proper accelaration and deccelaration lanes at junctions...

As for the Bohumín bypass, it really is is a huge relief for Bohumín town, because the current (since today former) route is not suitable for trucks at all.

Like this?
No and No.

They opened in fact only bridge over the railway. The local setup next to the motorway is opened already some time. In use is following.



It may be much ado for nothing, however the bridge is rather nice. https://picasaweb.google.com/1061025...CIrG6Yvm_crCYA thanks to hiob and ceskedalnice.cz

Short video of D3 near Tábor, currently the only section of this motorway in operation. The Tábor bypass section is of much worse quality than the rest, with deep track formation.

The EU commision brought up new proposal for the core axis in the TEN-T planning (TEN-T revision). See http://ec.europa.eu/transport/infras...ision-t_en.htm

As for CZ there are quite some changes. E.g. the D3 connecting CZ and Austria is not anymore marked in the core network but in the comprehensive only. On the other side the D11 heading to the north connecting CZ and PL is now in the core cathegory (I guess former priority axis).

Some local polititians from south CZ said that the EU commission doesnt alocate any money for the D3 sections in the 2014 framework. Above that, when I compared the commission maps from may 2010, the revision proposal, and the actuall state, there is mess in it. The dates when roads should be operational dont match, E.g. D8 is marked as completed already before 2008, D5 as being under construction in 2010 etc.

Who is responsible for this mess? Czech authorities? Commisison authorities? How is it possible that in ohter countries is it possible to plan construct and finance without such chaos?

First class road I/37 connecting Hradec Kralove and Pardubice (twin 90k + cities) in North Bohemia. map: http://www.mapy.cz/s/2tWh

South of R35 intersection.



North of R35 intersection.



The construction is divided into two section. South of interchange with R35 and North of R35. In the south new 4 km section of this road should be operational by the end of November. Some last 0,6 km in the summer next year. North of R35 should be finished in the end of 2012.

This 2x2 first class road might be the first first class (I) road in CZ with 110 km speed limit.

R35 meets I/37 by Hradec Kralove

It's been a while since I posted some new footage of the Czech Republic, due to my computer acting up. Now I got a new PC which renders videos incredibly fast (from 30+ minutes down to 3 minutes).

R6 Karlovy Vary

The R6 and route I/6 through Karlovy Vary.

D1 Praha - Brno

I've read they are going to start the full reconstruction of D1 between Praha and Brno in the next few years. I've also read they want to operate a 3-0 system (2+1 lanes on one carriageway) which will cause major disruption of traffic. They want to divide the work in 25 phases. The works will take a whole decade.

I wonder what the best approach for roadworks on such scale is. I'm not sure if they meant 25 sections or 25 phases. If it's the first, this means the average section is only about 7 kilometers long. If they double that to 15 kilometers, they can shave off much more time. I'm personally a fan of the quick-and-heavy approach, rather than the long-and-somewhat-less-heavy approach.

The main cause for traffic disruption will not be the single lane section, but rather the point where it narrows from 2 to 1 lane. I rather drive 5 years on 15 km one-lane sections than drive 10 years on 7 km one-lane sections.

I think it's technically doable to execute the works in 3 years (on and off sections) but it would be expensive and the traffic disruption would be extreme (delays of several hours over the entire Praha - Brno route)

Nothing is sure at this moment, they are still considering a 2+2 (4-0) variant during the works. This might be enabled by paving additonal 0,5 to 1 m along the carriegway, but there is not enough space on some section and they fear that it won't bear the load of trucks... We'll see in next months what will be chosen.

Is there already an exact opening date known? In August works were pretty advanced, just 2 or 3 bridges they were working on.

Full profile opening is to be expected in April 2012.

I think that they should rebouild D1 Praha-Brno to 3+3.

Nah, traffic volumes drop below 40 000 after Mirošovice and only increase over 40 000 until you reach close to Brno.

I believe there are some plans to widen the D1 near Brno though.

in HR we had similar thing: A3 was reconstructed in lenght of 190 continuous kilometers. on 3/4 of that route both upper and lower layers were removed and made again, and on 1/4 only upper layer was changed. the principle was attacking the route on more places at once on lenghts up to 10 km. averagely traveling from Zagreb to east you had to pass 8-10 large construction sites. it lasted for cca 3 years (replacment of overpasses at exits not included, just as few bridges, which were reconstructed later).
personally i prefer that way instead of closing whole half at once.

The problem with D1 however, is that it carries twice as much traffic as Croatian A3, and probably also more truck traffic. A work zone is not the worst problem, the main cause of congestion will be due to the 3-0 work zone configuration.

In the Netherlands we have a wide shoulder so a 4-0 90 km/h (sometimes even 100 km/h) can be operated.

that's right. but those narrow 2+2 things (or 4-0)... khm, i doubt how would they work. you can have them in NL with really wide shoulders, but with usual shoulders 2,5 m wide it is useless.

Well Dutch motorways are very busy. 80 000 vehicles per day on 2x2 is very common. We can't afford to have capacity-reducing road works like 3-0 / 2-0 or 60 km/h 4-0 like in Germany.

Our new motorways are being built with 11,5 m wide paved carriageway to accomodate 4-0 setup, but D1 was built with 10,75 wide carriageways that do not fit for 4-0 setup. So we either need to survive the 3-0 setup unless at least one new wider carriageway is built, or we need to invest to additional paved strip etc. BTW today many news articles were published stating that the police refused to support the 3-0 setup and they demand 4-0.
