model railway G scale arched truss bridge

As the bridge isn't symmetrical I have mirrored it so it doesn't look odd. I have also made the other side easier to glue together.

G scale model railway Arched Truss Bridge. Only the sides. The base can be made from wood and then the sides attached.
The top supports allow the sides to be 150mm apart.
I used PLA+ on one side and PLA on the other. I would certainly use PLA+ (or PETG).
It is 1000mm across.
