Mono Arc Bridge

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.A description how to assable coud be found in the thing part.Here a link to a Video. 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.
