This kit builds into an OO scale model of a stone built, twin track rail-over-single track road bridge. It is closely based on a prototype found in the Ribble Valley. The main structure is laser cut from plywood, with the corner overlays and tunnel walls cut from card. Both sides of the bridge are included, along with a fully etched stone interior to the tunnel.
The model is designed to be built into a double track railway embankment and includes full colour assembly instructions.
