Timber Culvert Outlet with Riprap

A heavy squared-timber culvert portal built from stacked baulks with visible spike heads and iron strap plates at the corners. The square mouth opens onto a planked interior throat, with plank wing walls returning along one side and a solid boarded head above the opening.

Spilling from the mouth is an apron of loose riprap in mixed grey and warm brown stone, graded from larger blocks at the lip down to smaller rubble, all laid on a flat pale concrete slab that can be sunk into a scenic base.

Made for the foot of a road or rail embankment, a drainage outfall into a stream bed, a mine adit entrance, or as a defensible crawl-through on a wargame board.
