Quite similar to Italian Superstrade, actually.
Right. Also the distance b/n interchanges can be less. But all these differences usually applies to NEW roads. There are a lot of existing "Blue Autobahns" with lower standard than "Yellow Autobahns", e.g. some A4 or A8 sections w/o hard shoulders.

The urban B74 in Bremen was rededicated to A270 in 2001 while the road has no hard shoulders. The B6n b/n A395 and A14 was built b/n 1997 and 2011 (with hard shoulders). The region wants a rededication to a Autobahn but the official statement is "no Autobahn standard". But the standard is much higher than the A270...

A common road user does not detect any difference b/n "Yellow Autobahns" and "Blue Autobahns".

Another argument for planning a "Yellow Autobahn" instead of a "Blue Autobahn" is calming the NIMBYs (e.g. B26n, B15n, B29, B14,...). Autobahns are bad, B roads are better.

The color of the signs! (that's not a joke, that's exactly my opinion!).

I don't know if this was already posted but:

Quote:
Femern A/S has now completed a 10,000pp application to build a fixed link across the Fehmarnbelt. It will be delivered to the Schleswig-Holstein authorities in October, 2013, getting the regulatory approval process underway in Germany.

Over a four-year period, Femern A/S has set out three alternatives: the main project, an immersed tunnel; a cable-stayed bridge; and a bored tunnel. The alternatives have been thoroughly investigated and their impact on the environment analyzed in depth. As a result of the many studies conducted by a large team of international experts, the immersed tunnel was designated as the Femern A/S recommended option. This will carry a four-lane motorway plus a dual-track electrified railway, and is projected for completion in late-2021. Construction is due to start in the summer, 2015.

Information about that tunnel is mostly posted in the Danish thread, because it is chiefly a Danish project.

True, I posted here because the news involved Schleswig-Hohlstein and German approval.

I read the first part regarding the documentation in late June 2013. I planned to post it here but it wasn't worth... The immersed tunnel info was announced about 2 weeks ago but I was very busy at that time. Sorry...

I also read about preliminary works should be started now. It is a construction road to the future tunnel construction on Danish side. It should effect a reflection for the local companies.

Further info (published since May 2013):
- The tunnel option features hard shoulders
- Vmax 110km/h in the tunnel
- The (old) German Bundestag prefered a tunnel instead of a bridge.
- The German plan approval procedure is announced to be started in fall 2013. The order should be passed in early 2015, construction time summer 2015 to late 2021.

Here in North-Rhine-Westphalia there are several substandard Autobahns, having an A number (usually 3 digits) and blue signs. Most of them are not Reichsautobahns from the 30's but were built in the 60's and 70's. Many of them are rather short, e.g. A573: 3km A571: 2.5km.

However not all A5xx motorways are substandard, e.g. A555 is quite wide and straight.

A40 through Bochum and Essen is very substandard IMO.

That busway is very weird. Should be converted to rail IMO.

When did they open that tunnel in Essen?

It's a guided busway, the "O-Bus" to be precise. one of the earlier systems, in operation since 1980. The guided busway of Adelaide uses the same technology:

Another quick question: is the substandard (but fascinating) A8 section near Mühlhausen im Täle already interested by the new alignment works or are they still in Planung?

But the planning of the new "Albaufstieg" is in standstill.
Why this question?

I was discussing in the Italian thread with someone about A8 and we weren't sure about that very spot.

Almost. East u/c (together with the Stuttgart-Ulm HSL along it), west completed.
There's not work on the Albaufstieg itself at the moment, that's correct.

A8 Karlsruhe - Salzburg

Quote:

Yes. The part west of Mühlhausen is already completed.

The entire A8 b/n Karlsruhe and Salzburg was opened b/n 1935 and 1941. It is a so-called "Reichsautobahn", 2x2 w/o hard shoulders. The total A8 length is 392.2km (w/o part near Saarbrücken).

The A8 was already upgraded to 2x3 with hard shoulders. The last missing gaps are:
- AS Karlsbad – AS Pforzheim-West (OSM; 9.1km; u/c August 2009 to early 2015)
- AS Pforzheim-North – AS Pforzheim-South (OSM; 4.8km; plan approval procedure in progress; discussion, discussion, discussion,...)
- AS Mühlhausen – west of AS Merklingen ("Albaufstieg"; OSM; ~8km; realignment; plan approval procedure stopped due to open funding concept)
- West of AS Merklingen - AS Ulm-West (OSM; 22.9km; u/c May 2012 to late 2018 in 4 phases)
- AS Ulm-West - AK Ulm/Elchingen (OSM; 11.7km; in planning stage)
- AS Günzburg - AS Augsburg-West (OSM; ~41km; u/c August 2011 to September 2015; PPP)
- AS Rosenheim - DE/AT border (OSM; ~69km; in planning stage; discussion, discussion, discussion,...)

Conclusion: About 40% of the A8 b/n Karlsruhe and Salzburg are still "Reichsautobahn" standard (2x2 w/o hard shoulders)! 73km (18%) are currently u/c (until 2018).

I guess no further section will be started until 2020.

Between Rosenheim and Salzburg there are not only discussions but some concepts to realignments as well, especially in Piding.

I know .

It is in an early planning stage (since circa 2008). There are a lot of concepts and ideas - especially NIMBY created ones. For instance the "4+2 concept": 2x2 upgrade with hard shoulders but no 3rd lane! There are also concepts with realignment.

2x3 widenings of German Autobahns are usually no big deal: everyone wants the upgrade some people want to get better noise protection etcetera. The A8 project is different.

Nevertheless, the replacement of the "Talbrücke Bergen" viaduct is already u/c (May 2010 to June 2014). Furthermore there are six planning sections. The two westernmost sections recently got the "Gesehen-Vermerk" (approval notation) by the Federal Ministry of Transport (2x 8km sections b/n AS Rosenheim and Bernau; source). Both plan approval procedures could be started "soon" (within the next 1-2 years). The other four sections have not yet got the "Gesehen-Vermerk" (approval notation) due to unfinished planning documents. In best case the first section could be u/c before 2020.

Construction delays

The B62 section b/n AS Siegen-Dreisbach – AS Niederschelderhütte will be opened in fall 2016 (instead of late 2015; 2x2/2x1; 1.9km; 81 million €; OSM; extension of "Hüttentalstraße"; plan approval order: November 1980; u/c since April 2010). Delay reason: highly complex situation with construction of a bridge.

The B243 section b/n Bad Lauterberg and Bad Sachsa will be opened in August 2014 (instead of October 2013; 2x2; 8.6km; 78 million €; OSM; plan approval order: December 2005; u/c since October 2008). Delay reason: soil settlement due to caves.

The B464 section b/n south of Renningen and AS Magstadt will be opened in spring 2015 (instead of July 2013; 2x1; ~1km; 14.7 million €; OSM; plan approval order: 1999/May 2011; u/c since early 2012). Delay reason: ???.
