Ok, I didn't know that.
Because Rhineland-Palatinate, Northrhine-Westphalia, Saarland and Hesse just use K in every Landkreis, and I thought, the rest would too

The system is pretty easy (very similar to the US system):

A = Autobahn: fully grade separated, separated direction lanes with 2 or more lanes each, lanes 3.5 or 3.75m wide, mostly with 2 - 3.5m wide shoulders.
Of course there are a few sections which still wait to be upgraded to this standard, especially old Reichsautobahn sections generally don't have shoulders and deceleration/acceleration lanes, but all are planned to be upgraded.

Autobahn is a road type and a classification. They are signed blue. All other roads are signed yellow (inner city destinations white) and are only a classification, not a special type of road:

B = Bundesstraße (federal road). A and B roads make up Germany's long distance road network and belong to the Federal Republic of Germany (except B roads within larger cities).

L = Landesstraße (Staatsstraße in Bavaria and Saxony), belong to the Bundesländer.

K = Kreisstraße, Patrick already posted this before.

B, L and K roads can be normal 1+1/2+2/... roads, parallel one way roads (one for each direction of course) or 'Kraftfahrstraßen'.
The term 'Kraftfahrstraßen' (colloquial 'Schnellstraße') is used for every road type limited to motor vehicles. They can have only one lane per direction, no separation between direction lanes and sometimes even at-grade-crossings.
'Gelbe Autobahnen' are a special kind of Kraftfahrstraßen: they meet Autobahn standards and thus don't have a general speed limit. But as they don't belong to the A network but to the B,L or K network they are officially called 'autobahnähnliche Straßen' and have yellow signage (that's why 'gelb').

It's all politics and NIMBY's. Think of the A21 and the B6n

Check this thread about my road trip for a lot of pics and video's of German autobahns.

What I also noticed, that very few people drive very fast. Only on some quiet Autobahns, like the A31 people are flying by with 180km/h, but on most autobahns, most people don't drive over 140/150km/h.

Trucking is becoming an uncontrollable problem on German Autobahns, they really need to mass-widen Autobahns to 2x3 lanes, otherwise the traffic jams will become very bad.

However, compared to the Netherlands, it's not so bad, Germany need to have 1.700 kilometer of traffic jam to have the same situation as the Netherlands, when counted to population. Germany is nowhere near that, 300km is already pretty much.

oh, I've just seen, that the owner of www.autobahnatlas-online.de just updated his gallery. Here are the pics that I have taken a month ago. Thx to him for hosting



A3 Dierdorf - Köln (33 photos, whole tour here and here)

These boards replaced the Racing ones (which can be found somewhere in this thread )

Old bridge, nicknamed "Gate to the Westerwald"

after the join of the A4 in Köln



A64 LUX-Wasserbillig - Trier (14 photos, whole tour here)

Bridge over the Sauer river

This autobahn is not completed yet, and there are no concrete plans to do so.



A66 Wiesbaden - Wiesbadener Kreuz (11 photos, whole tour here)

Strange: Kastel is not a district of Wiesbaden's neighboring city of Mainz. Mainz-Kastel is a district of Wiesbaden, which has to be explained with new border drawing after World War II.

Heading to Frankfurt



A560 Siegburg - Sankt Augustin (8 photos, whole tour here)

Mülldorf means "garbage village". Must be a lovely place to live



A643 Mainz - Wiesbaden (9 photos, whole tour here)

old and narrow bridge over Mainz-Mombach

it depends on where you are. On the A3 for example, many people drive faster than 150km/h, but on the A48, only a few fly by. but the number of these is decreasing (including me ) because of the gas prices.

The crashbarriers have the great shape, not the typical ugly shape.

Today I saw some very new crashbarriers that were very very very shiny, and nicely shaped of course

What kind of shapes are there? The crash barriers I see in the U.S. are all pretty ugly to my eyes. most of them are rusted too and use wood supports.

A few meters (30 or so) on the George Parks Highway north of Nenana, Alaska. Brand new layer of asphalt and because there is a creek overpass, they installed some crashbarriers there. And yes, most American crashbarriers are very ugly and rustly. Today I went with a tour up the Dalton Highway to the Arctic Circle. Not a lot of pics though, since I was in the middle of the bus. The Elliott Highway is one of the most horrible asphalt roads there is, since water gets through the asphalt in summer. It freezes in winter, elevating the road surface at some spots, causing big bumps. The Dalton Highway is quite good though, despite its gravel surface.
Tomorrow I drive down from Fairbanks to Valdez, and I also hope to make some nice pics.

Concrete barrier:


A-Profil: parts of northern Germany, parts of Bavaria and the whole Rhineland-Platinate use these type of crashbarriers.



B-Profil: about 80% of all autobahns have this barrier.




radi, i am very sorry, but i guess you will be disappointed. bad weather = bad pics:

I really like the B-Profile barriers. nicely colored and looks more "advanced" than A-Profile barriers or concrete barriers. Are concrete barriers popular on the Autobahn? I also noticed that behind a lot of the crash barriers, there are more guardrails. What are those for?

concrete barriers (jersey barrier) are getting more popular due to higher security standards.
