The bridge for games was manufactured.
This is Plastic Kit made from Rendra which can be purchased by a perry miniature.Although sold as Pontoon Bridge, manufacturing as a bridge is also possible.
This is perfect exactly for the width of the model of the river which I am using.
I think that the actual bridge is more dirty.
however, since it was an object for games, it came out to this extent and stopped.
Pontoon Bridge is also under manufacture now.
