Some weeks ago, I drove on the A3 in Germany, and saw an interesting bridge crossing the highway.
It was a mono arc bridge and I thought this would look good in our marble run.
The bridge was planed and build by
www.ssf-ing.de where you can find further information.
Update 16.09.24:
As most people have problem with the press fit of the square holes and pegs of the arc, I made the square holes biger.
A description how to assable coud be found in the thing part.
