Twin Box Concrete Culvert Headwall

A cast concrete twin-cell box culvert set into a low embankment pad. Two square openings sit under a slab deck, separated by a central pier, with flared wing walls sloping away on both sides and a stepped kerb along the top edge.

Surfaces are plain formed concrete with visible panel joints and light rust staining at the invert, and the barrels are open right through so water, debris or scenic filler can be seen inside.

Useful anywhere a road, embankment or railway crosses a drainage ditch or stream: highway verges, industrial spur lines, or a stream crossing on a wargame board. Also serves as a drain outlet in an urban flood-control scene.
