From all gaps in the German Autobahn network I would love to see this one closed as soon as possible:

A4

A reasonably direct route is about 110% of the great circle distance. Which one in your list is not more than 120% of the great circle distance?

I agree. Completion of the A4 should be a priority for the next federal road plan of 2015.

Don't count on it. It's not in the mindset of politicians that this is a missing link.

For me A38 provides a great alternative anyway.

Closing the gap in the A4 would, assuming an intersection with the southern end of the A49, make the A38 much more useful for traffic to and from France.

Koblenz to Giessen also has a nasty gap.

When I first started driving to Poland, I'd use the E40 all the way, starting from Calais, and via Köln, Olpe, Giessen and Siegen and all that shit. And then the Polish part from the border wasn't even finished yet. So I thought sod this, I'm going via Berlin, which I did, and then drop down to connect with the completed part of the A4 in Poland. But now they've completed the A38, as well as the A4 from Poland, I'll keep on using that, even if they did complete the A4 in Germany. From Calais via Venlo, Dortmund and Kassel I never got there so quick, also with the now (badly) completed Polish A4 from the border. And I really don't like that A4 bit after Eisenach anyway. So I don't care if they complete the A4 or not.

A60 Mainz

The Mainzer Autobahntunnel opened to traffic today. This concludes the widening of A60 along the south side of Mainz. Works to widen A60 started in 2001. The construction of the tunnel itself began in 2006.

A4 "gap": There's no need to build a new Autobahn through very hilly terrain just for a few thousand vehicles a day. Extending A45 Olpe-Gießen and A5 Gießen-Hattenbach (and closing the short A480 gap near Gießen) to six lanes is the much better option and provides drastic improvements for many traffic relations including all those traffic from Dortmund, northern and eastern Germany to Frankfurt vv.

Koblenz-Gießen will never be built. But the B49 Limburg(A3)-Wetzlar(A45) is upgraded to Autobahn standard currently.

Falling arrows were only used in Hesse. With the first Autobahn widenings to 8 lanes and complex interchanges around Frankfurt in the 70s, the Hessian traffic department was looking for a new signage system, because the standard German one reached its limits with these projects. They adopted some elements of the US system, including the falling arrows, and created Europe's most sophisticated signage system (besides the old Dutch one). With Germany's RWBA (Richtlinien für die wegweisende Beschilderung auf Autobahnen - guidelines for direction signage on motorways) from 2000, they had to drop the falling arrows, but the key elements which aren't fully contrary to the RWBA are still in use in Hesse: one arrow for each lane, exclusive use of short arrows which have to be placed in the middle of the corresponding lane below the destination texts (no long arrows next to the texts which can be seen rather often in the rest of Germany), maximum 4 destinations per board, centered left-aligned typeface etc. Wikipedia article with pdf links to the Hessian guidlines: Click (German only).

The hilly terrain might be a good reason to not build an autobahn there, but the AADT would be a lot more than a few thousand if they were to build it. It would carry more than a few thousand vehicles per day of international traffic.

Closing the A480 gap is a good idea. I'll take your word on the need for widening the A5 and A45.

Do you mean that it's currently being upgraded? Or that it's already upgraded? In other words, is it now under construction or is it completed?

Anyway, an autobahn connecting Limburg and Wetzlar would provide a useful autobahn route between Koblenz and Giessen.

ps: "extending" means, in the context of highways, lengthening not widening.

Hilly terrain is EXACTLY a reason to build a highway: when you have flat terrain, local roads can cope with traffic at reasonable speeds. When you have mountains, even if the place is sparsely populated local old roads are too slow. Best example: southernmost Italy.

The potential gain in time in hilly or mountenous terrain is bigger of course. Italy is indeed a prime example. But there is of course one key difference between Italy as it stood before the main North-South motorways were constructed and Germany as it stands now. Namely the existence of existing motorways that form a detour. Surely one might gain an hour with a direct Olpe - Hattenbach connector, but its cost:benefit analysis does not come remotely close to that of a route like the Italian A3 built in a region where other through motorways are pretty much absent.

A 4 gap: Existing A 45 - A 5 can cover the link with only a small detour. A 480 should be linked from Wetzlar to Gießen as fast as possible, though.

A 48 gap east of Dernbacher Dreieck: B 49 Limburg - Wetzlar is currently being upgraded to expressway standard, that should do it.

Btw, A 48 was planned to run from Luxemburg (now A 64) - Trier - Wittlich - Koblenz - Stadt Lahn - Krirchheimer Dreieck. The last section is now part of the A 5, which was originally supposed to go North from Gießen and finally ending in Bremen (today's A 281)

There are some other gaps that have always intrigued me why they have never been closed.

1 - A8 between Pirmasens and Karlsruhe or probably Stuttgart if a new southwards A8 would have been built between these two last cities.

2 - A49 east of Darmstadt.

3 - A90 betwwen A2 and Augsburg.

4 - A99, the southern contour of München.

Are there any chance of being closed in the future?

There are no longer (official) plans to build these. They were abandoned for the obvious reasons: limited demand, also in light of the existing Autobahn detours, costs and ecological impact.

But if you speak of "any chance", the plans might still return in the future. In particular, high levels of traffic supply on existing Bundesstrassen or on other motorways may lead to a revival of old plans in some form or another. In particular I can see renewed interest in completion of the Munich ring road as a mitigant to the situation on the North and East side of town. They might also add extra lanes to the B10 between Pirmasens and Landau, but I cannot see that road being upgraded to full motorway as a result of ecological sensitivities.

Man, you must have some confidence (and a nice car) to drive so fast on such rainy road. But you gotta love no speed limits on German autobahns!

Am I correct that the speed limits on the A2 between Dortmund and Berlin have been removed ? 152 km's extra of unlimited Autobahn . Finally a victory for motorists rather than old annoyed dinosaurs... Thanks to the the FDP . Only dynamic speed limits potentially to conditions, no more crappy 120 km/h in the middle of the night .

Beside some speed limits around bigger cities and autobahn intersections there is no speedlimit on the A2 from Oberhausen to the beginning of the Berlin orbital autobahn A10.
