concrete roads might be strong, but they are not confortable to drive on, no matter what car you have, thick well doen asphalt will always feel better, softer and saver then hard concrete.

well, i think its a good compromise: a little comfort for durability

our phantastique brand new M0 east sector is made of concrete and the drive feeling is not so bad...

How is the M5 doing, it still feels awesome, it´s probably one of the best feeling motorways not only in Hungary. I think the asphalt used on the M5 was very good.

I don´t trust one word Wikipedia anymore, I found so much wrong information there, that it´s hard to believe what they say.

So many of these "motorways" are only 2 lanes. Are they congested much? What percentage of German Autobahns have 3+ lanes?

I ask because expressways in the UK with 2 lanes cannot be called a motorway/autobahn despite the same speed limits and road surface quality as 3 lane motorway.

I'm not talking about structural damage, but just the pavement. But I guess it strongly depends on what kind of pavement, such as different types of ashpalt or concrete.

Any plans of filling the A33 gap near Bielefeld? I heard that works on a short section started but don't know any details.

Also, are there any plans to extend the A-45 from its 'ghost' interchange end at the A-3 by Aschaffenburg? Where is/was the A-45 planned to go? (Feed into the B-469? Split with one leg also feeding into the B-26?)

In den 1960er und 1970er Jahren sollte die Autobahn im Süden als „Odenwald-Neckar-Alb-Autobahn“ (ONAA) über Groß-Umstadt, Michelstadt, Schwaigern, Neckarwestheim, Mundelsheim, Berglen, Remshalden, Lichtenwald und Schlierbach bis zur A 8 bei Kirchheim unter Teck verlängert werden. Diese bereits recht weit entwickelte Planung wurde jedoch im Jahr 1979 durch die baden-württembergische Landesregierung aus ökologischen Gründen offiziell aufgegeben.
During the 1960's and 1970's it was planned to extend the Autobahn southward via the several minor places meant in the article to the A8 Autobahn near Kirchheim unter den Teck. It was planned quite far, but cancelled on environmental grounds in 1979 by the government of Ba-Wü.

I am wondering which Kirchheim unter Teck it is talked about here, probably not the Kirchheim unter Teck where the A8 passes, because 10 km away from there I live in Germany. Currently vacation in Bulgaria.

There is only one Kirchheim Unter Teck according to the German wikipedia. That one makes sense given the route of A45 towards the A8 east of Stuttgart.

The whole Ruhr Area is now jammed due to snowfall. Numerous traffic jams between 15 an 40 kilometers.

I have a question about crash barriers. Are German Autobahns using Concrete Step Barriers (also known as the F-Shape barrier) or are they mainly using steel?

They use concrete in the middle and steel at the sides on their new motorways, old motorways are steel only.

Wrong. There is plenty of 2 lane motorway in the UK, what makes it different from a standard dual carriageway is whether or nor motorway regultions apply - no learners, mopeds etc. It is not actually necessary to have a hard shoulder as seen with several of our urban motorways. what we could do with is the level of construction witnessed in Germany. Perhaps more to come with the new capital spending package under discussion in Berlin ??

Thanks! Do you know how they're used? Is there any vegetation in the median or is it just a wall of concrete going down the middle?
