Both A3 and A92 are closed today. The flooded city of Deggendorf is basically cut off from all major access roads.

At least a little bit of sun. But that is really a lot of water, judging by the level of the roofs...

Building in a flood plain is really stupid. However, I'll bet that the government not only allows everyone to rebuild in the same places, but even allows them to rebuild below the flood level (i.e. without raising the buildings on stilts or above floodable walls).

Mankind has been living on settlements along flood plains since the dawn of history.

Moreover, you can build dykes instead of raising buildings. As Netherlands does.

Living in flood-prone areas has increased significantly in recent decades due to insurances. This is one of the primary reasons why there is such incredible damage after hurricanes and floods in the U.S. Previously insurers could refuse someone living in a flood-prone area.

Thing ist: Probably 90% of the buildings flooded in the pics above are flooded for the first time ever. And if there was a building before, it quite possibly was never flooded. This is plain and simple a flood beyond imagination.
As bad as it is for everyone affected, but due to gauge prjection systems and efficient civil protection (were a lot of money was invested after the last bad floodings of 2002) the consequences (at least in Bavaria) will quite possibly be way less catastrophic than during the last floodings roughly that bad in 1954. And possibly every major flooding on the Danube before the 20th century.

That was 1953 (Netherlands, Belgium, East-England), 1954 (Germany).

The dikes they are re-building in the Netherlands (Zeeland) are strong enough for storms/floods in more than 1000 years. We have to, because we are living below sea level.

Hopefully does the situation get better in Germany.

Does anyone know if the A11 still has bad segments or if the entire Autobahn has been renovated by now?

In Passau this flood was 70cm higher than any known flood in the history (up till now the highest flood was recorded in 1501). The same is true for all of the Bavarian flood-locations.
The main reasons are extremely rainy weather of the recent weeks and very long winter with a cold spring which made the snow in the mountains not to melt. A great amount of snow has just melted and has been washed to the rivers by heavy rains.

Yes its a very extraordinary combination of events that caused this extreme flood. Nearly all rivers that feed the Danube have their source in the Alps including rivers like the Inn that flow from deep inside Austria to the Danube in Eastern Bavaria. In winter, even with the same amount of rain, it will never get to the same floods because above a certain height it stays as snow and melts over the course of weeks. In summer when the temperatures are higher there is hardly ever so long and so much rain in the complete source / feed area of the Danube.

Sure you can have a look at making some changes, the flooding of the A8 near the Chiemsee could have been prevented if there were some (higher) dikes along the last few kilometers before the river ends in the Chiemsee.

But further down the line you can calculate once every 500 years the water comes above a certain height and its probably cheaper to let it flood than to protect the whole 2857 km of the Danube against extreme floods.

Trying to contain rivers is a losing strategy. There will always be some volume of water which will overflow any artificial river bank. In my opinion, the better strategy for dealing with river flooding events is to build buildings which can withstand any flood. Stilts are one of many possible approaches. When the buildings need to be rebuilt anyway, building them to withstand unexpected floods is probably much cheaper and more reliable than trying to build dikes along 2857 km of the Danube.

I note that the problem faced in the Netherlands is rather different. In the Netherlands, extreme rain is not the corner-case problem. The corner-case problem is a freak tsunami. In Japan, TEPCO refused to consider even the possibility of a 10.2m tsunami but the tsunami that hit on 11 March 2011 reached 40.5m (elsewhere in Japan).

Part from 86,0 to 90,5 (direction Szczecin), except some bridges, has not been renovated yet. Pictures shoot last sunday:

Right! DK6 near Szczecin has similar pavement for a few kilometers.

A92 is open again, A3 still is closed and might be for a few more weeks (!).

That's funny. I've used A3 from Nürnberg to the Dutch border last night...

A1 News:

- The plan approval procedure for the A1 widening (2x3) from AS Neuenkirchen/Vörden to AS Bramsche was started in April 2013 (OSM). This section has a length of 9.9km. Construction start is estimated for 2017.

The A1 is already widened to 2x3 between AD Ahlhorner Heide (A29) and AK Osnabrück/Lotte (A30). The last 2x2 exceptions are the above section and the section from AS Lohne/Dinklage to AS Neuenkirchen/Vörden (OSM). The plan approval procedure for the 19.5km long section was started in October 2011. See project page.


- The A1 from Leverkusen to Köln (OSM) was closed for trucks some weeks ago. The Rhine viaduct is decrepit and must be renewed. The new viaduct shall be widened to 2x4 lanes. There are discussions to built a tunnel below the Rhine instead of a new viaduct. There are also discussions regarding alternative viaducts to the south or to the north of the current A1 viaduct. Also a housing tunnel instead of the stilt brigdes in Leverkusen is proposed. What do you think about that situation?

News:

- A7 widening (2x3) between Salzgitter and Göttingen (OSM; last 29.2km long gap): The Federal Court of Auditors ("Bundesrechungshof") has asserted that PPP would be more expensive than a conventional construction. The costs would be 12.8 million € higher. The Lower Saxony Ministry of Transport is happy, but the final decision will be made by the Federal Ministry of Transport.

- The 4th A20 section from Bad Bramstedt (A7) to Wittenborn (OSM; 19.7km) will be completed in 2018 - at earliest. The plan approval procedure is still in progress. It was started in July 2009 and its conclusion is estimated in late 2013.

- The trial at the Federal Administrative Court for the 3rd A20 section from Wittenborn to Weede (OSM; 10.0km) will be on 22nd and 23rd October 2013. The plan approval order was passed in April 2012 (started in October 2006).

- The B109 Levenhagen bypass will be opened on Monday 10th June (OSM). The plan approval order for the 1.9km long road was passed in December 2010. The construction was started in May 2012 and costed 3.5 million €.
