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 (10) deflects debris to maintain the pillar clear from any unwanted build-up of rubbish. The apparatus utilizes at least one finned cylinder (30) that is rotatably held in place in front of a pillar (50) with an upper attachment bracket (26) and a lower attachment bracket (28). The 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 cylinder in the preferred embodiment. Any number of cylinders may be used in tandem, according 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.
