Historic Landwasser Viaduct (large Brio bridge)

This model is designed to be compatible with Brio wooden train tracks and captures the essence of this famous Swiss railway bridge, known for its curved limestone structure and its direct connection to the Landwasser Tunnel. The goal of the model was to create a bridge that is double the hight of normal Brio bridges.
