This all came before you hit Germany yes? .... :/

It was pretty steady actually - both in Austria and in Germany. speed up...slow down...speed up...slow down. The "play-street" (domestic zone?) sign is of course the joke as it would never be put on the highway :)

With the exception of the joke "playing street" sign, all of this happened on the highways (Autobahn). Lots of construction (and destruction) going on it seems. There were two off ramps just gone and I had to take a 30km detour because of that.

I honestly don't know which road it was... I was driving by GPS. You know: "turn left in 100m" kind of instructions. But judging by what I remember, it might have been this junction here that gave me the most headache: http://maps.google.com/maps?hl=en&ll=51.236772,12.059898&spn=0.076094,0.160675&sll=37.0625,-95.677068&sspn=48.909425,82.265625&geocode=FRKz4QIdBMryACH2TQRjG6bYASk15qmIInptRzH2TQRjG6bYAQ%3BFfdzGwMdTnGxAClb6tpV__WlRzFgEAf4WWYjBA&oq=magde&mra=ls&t=m&z=13
Two of the ramps there are just not there anymore. Gone. Not only closed but removed. Road and ramp. "Under Construction" they call it :/
