Pre-fabricated end wall for culvert includes a novel pre-cast concrete slab shaped with an upper margin longer than the lower margin and with inclined side or end margins which are proximate the angle of repose of the culvert or ditch in which the culvert end walls are to be inserted. Each end wall defines an aperture into which mates or nests a conduit which is adapted to pass water from one end wall through the other end wall. Backfilling is the usual aggregate is compacted into and between the end walls to complete the culvert structure and if desired, a roadway surface may be placed over top of the same.
