Reminded me from the old days that I always missed the bridge over the moat* of my built sandcastle.

With this 2-piece mold and shovel for a smooth road, and a good sticking sand mix, this should be a piece of cake.

See the photo with the instructions for usage.

The Bridge Deck Scoop is also usefull to pave the road from and to the bridge… When scaling the bridge parts, don't forget to scale the scope correctly with the right factors!

* The model can also be used as a viaduct by placing it between 2 ascending "roads" / ramps.

Update, version 2:

By cleverly placing the lips, 1 part for both halves will suffice. So I added version 2. If you want to use this version, you have to print it twice. I made the lips a bit narrower and increased their number so that an even tighter connection is created after sliding them together. Thanks to Q_159 who took the time to contribute this clever idea in the comments section!
