If you take into account which East German's highways or Czechoslovakia's highways were built after 1945, then the Czechoslovakia's highways are the most advanced.

The motorways were there and served its purpose regardless of their age. And unlike their Czechoslovakian counterparts they actually formed a proper network with plenty of motorway-to-motorway junctions.
That aside the East German network contained 512,2 km of post-war additions by 1990. Czechoslovakia built barely more motorways in that period, if at all. Your assessment is not based on facts, that's for sure.

Hi all, sorry for the question.
I would like to know whether the Vignette in Österreich is only for Autobahn or even for the "normal" roads.

Thank you n advance for the answers.

An update to one of the currently ongoing reconstructions of the Vienna urban motorways, specifically the A23 around the "Inzersdorf" Interchange with the A2, in this area: https://www.google.at/maps/@48.15040.../data=!3m1!1e3

Here, they are replacing an elevated motorway built from pre-fabricated parts in the 1970s, as it reaches its end of life. They are replacing this partially with a new elevated motorway/bridge, and partially they build an embankment underneath the bridge, on which the new motorway will sit.

Asfinag's website lists this as two projects, one on the A23, and one on the A2:
http://www.asfinag.at/unterwegs/baup...9Fe-inzersdorf
http://www.asfinag.at/unterwegs/baup...ten-inzersdorf

On the A2 towards "Altmannsdorf", they replace the bridges one after the other, closing some lanes during construction.
On the A23, tearing down the old elevated motorway and replacement is all done w/o any closure of lanes, on a motorway that has only a marginal emergency strip; therefore, they built a temporary bridge widening to one side, and take down the bridge in smaller segments.

An animation of the 15 different construction stages is at https://www.youtube.com/watch?v=aevdYHCa_Yc, one more detailed on the current stages at https://www.youtube.com/watch?v=oBQxmbc5p44

The pictures below are from a tour on the A23 ~10 days ago just before stage (Bauphase) 3, since yesterday, they have started to use one part of the new bridge for the direction A23 -> Exit Inzersdorf (see https://goo.gl/maps/6aWA8TS2Q2T2):

Also dogs were interested in the construction works:


View southbound towards the exit Inzersdorf



Still on the same exit:



View towards the Wienerberg area, which has some of the nicest skyscrapers in Vienna. Some parts of the noise protection wall will be transparent.




View northbound, against the driving direction: the left part of the motorway is now used for the exit Inzersdorf:



View southbound: to the right side of the picture is the now used part, in the left part where the asphalt layer is missing will be the future median separator between northbound and southbound carriageways, they will share the same bridge. Median separators will be with concrete (New Jersey) on the embankment (where the asphalt layer is missing) and with metal guard rails on the bridge:


Almost same location, viewing northbound:



The expansion joints between bridge and embankment; the asphalt on both sides of the joint which will be reinforced to avoid uneven surfaces.



Of course, 3 days after the noise protection wall was built, the first graffiti appeared (reads "SCR", which is the acronym of Rapid Vienna football club; mind, on the next exit northbound, you are at the stadium of their local competitors, Austria Wien :-))


Under the motorway, we can see three generations of bridge building. On the left (round columns) the new bridge; in the center the old bridge from the 70s, and on the right side the temporary widening for the construction period (thus also not using stainless carriers..), so that they could move most traffic to the northbound carriageway and start demolishing the old bridge.





The new bridge will be ~5 metres wider than the original one, allowing for full-size emergency strips on each side. They couldn't widen the bridge more without getting an assessment of environmental effects ("Umweltverträglichkeitsprüfung" / UVP), which would likely be difficult to obtain in the middle of the city with today's standards of noise protection etc..

--

As mentioned above, they are building the new bridge not in one go, but as much space as they have currently - they take away a bit of the old bridge whenever possible, and then build a part of the new one, that's why you have different stages of construction visible:




Construction should be finished by mid 2018, for a total of 130 MEUR for A23, and 30 MEUR for the bridges on A2. If they could close the motorway during construction, you could probably do with half the time and half the costs... But it seems impossible to even think of such a measure, with 145.000 vehicles per day in this section :-)

(For full size resolution of the images, click on them)


EDIT: A few screenshots from the ASFINA Webcam showing traffic on the exit Inzersdorf (far right side) at the beginning of the new carriageway, taken approximately from here: https://www.google.at/maps/@48.1525652,16.3572714,18z

The Karawanken Tunnel between Austria and Slovenia turns 25 years today.

Black-and-white photos as if it was 1960. But interesting anyway.

I've already noticed that many historical photos from the Eastern Bloc are black and white well into the 80s and even early 90s, while in the West black and white photos became largely obsolete by the middle-to-late 1970s.
Maybe there was a shortage of colour films and cameras capable to use them, like there were shortages of many things.

My father was an amateur photographer since he was 20 years old. My first pictures are also black & white as so was the camera he had back then (1989 and early '90s).

I guess they used black and white film because such photos last longer than color ones. Early color photos would get some redish shade after decades, at least I saw such photos from the 1980s. Color photography was common in Yugoslavia since late 1970s I would say.

Even today black&white satellite imagery is common. Google Earth has tons of it (usually not in the default imagery though).

An example in Austria:

Sorry, there was not such a thing as a black and white camera :-)
We used black and white films, right. I started to use color films in the early 90's. Using the same camera ;-)

The area where I live in Austria has the latest Google Earth imagery taken in year 2000 (16 years ago). It's color though.

Speaking of this... Google Earth is updating its imagery very often of some places around the globe, but most places in Austria are left without an update for years... while others are left completely outside the Google Earth imagery grid (check out the city of Liezen for example).

Is because of very strict privacy laws?

Europe doesn't seem to be a priority for Google. Until recently Germany had a lot of 15 year old imagery, and the Netherlands also had almost entirely 10 year old imagery until last year.

In some developing countries, particularly India, imagery updates are updated much often, some areas have over 40 updates per year.

Austria doesn't have 'base imagery' everywhere, which is the lowest resolution imagery. While this is common in northern latitudes, Austria (and Switzerland as well) still have some areas without base imagery.

Satellite updates can also depend on season (shadows) and weather of course. The northern hemisphere has far fewer updates during the winter, because it's either very dark with long shadows or white with snow and not a lot of detail.

There were also no Yugoslav politics at the opening - it was completely Slovenian opening on the south end as Slovenia announced independence day already months before. And if you look at the pictures with people cutting a band with big scissors, those are Austrian politicians, no Yugoslav.
