Rendsburg Loop - Germany

There are certainly several ingenious solutions, especially in places like Switzerland. The Gotthard spiral tunnels are one example, and this one that looks like a layout , the Bernina loop.

Here's a YouTube video. Check out around 1:23. Take that Horseshoe Curve!

I spent a year in Kiel, Germany in the early 90's and went to Rendsburg  often. Rendsburg is a very pretty town and that ride around the loop is great. There is also a pedestrian tunnel under the canal and a unique hanging bridge that carries car across the canal. 

All the best,

I just edited again. Did it work? I've had a couple of glitches posting pics lately.

Firewood, Yes it did!  Thanks

Very interesting. Rendsburg is north of Hamburg, west of Kiel (on the Kiel Canal) and just south of Denmark.

And both Danish and German influences over the centuries. Miketg

Then there's the spiral tunnels in Canada:
