A bridge pillar debris deflection apparatus (10), which attaches to a pillar supporting a structure located on a water way, such as a river or ocean. The apparatus (1 0) deflects debris to maintain the pillar clear from any unwanted build-up of rubbish. T he apparatus utilizes at least one finned cylinder (30) that is rotatably held in place i n front of a pillar (50) with an upper attachment bracket (26) and a lower attachment bracket (28). T he cylinder is rotated by the force of the water impinging on a multiplicity of fins (44 ) extending from the outer surface of the cylinder to deflect the debris and prevent any accumulation. An axle (38) is positioned between the brackets and extends through the cylinde r in the preferred embodiment. Any number of cylinders may be used in tandem, accordi ng to the need and environmental conditions. A variety of different brackets may be employed to attach the apparatus to a pillar or buttress, such as attaching plates (23), circumferencial bands (22), sliding brackets and even roller-equipped, movable brackets (46) that glide up and down the pillar.
