And there were lots more of them - Halle-Saale, Dessau, Braunschweig, Karlsruhe, Bautzen, Karl-Marx-Stadt, Lübeck... I'm sure our German members will be able to tell you more.
Mattijs just pointed this thread out to me - interesting!
There were several such circuits in Germany, since it had lots of ready-built motorways after the war, which were just perfect for motor racing of course. Dresden-Hellerau is still largely in the same state today, with only the tarmac renewed and many miles of Armco added. I drove across it in July this year. Check any map - it's the junction right next to the airport.
Halle-Saale was a city street circuit, no motorways here.
Karl-Marx-Stadt (Chemnitz) is another and I've driven on this stretch myself countless times. Easily recognisable on the map, too: it's the junction of the A4 and A72. However, the motorways there are completely rebuilt and widened into three lanes. What's interesting on this circuit was that they made a hairpin by having the cars doing a 180-degree turn on one of the motorways.
The Dessau circuit is very interesting - part of it was on the motorway, part of it on the secondary two-lane road leading to the motorway. The cars drove under the fly-over, but not over it.
The AVUS doesn't count, though, since it was a racing track first and only later became part of the motorway.
As for pictures: none, I'm afraid... you can't just stop on a motorway and shoot some

And of course they wouldn't be very interesting, I'm afraid. Just think of your everyday motorway view.
