PROBLEM TO BE SOLVED: To provide a bridge pier drainage pipe which improves the appearance of the drainage pipe set on the bridge pier. SOLUTION: The bridge pier drainage pipe includes a back face 51 which has drainage pipe metal fittings 80 fixed thereto, which metal fittings 80 engage with bridge pier metal fittings 90 fitted in advance to the bridge pier 2, a front face 52 which has an almost arcuate section and whose both sides are connected to both ends of the back face 51, and extension portions 53 which are formed consecutively on both ends of the front face 52 to cover the drainage pipe metal fittings 80 and the bridge pier metal fittings 90. Since the front face 52 has the nearly arcuate section, the front face 52 shows no angled part when seen from the front or side, thus offers an appearance better than that of a conventional drainage pipe that has a rectangular section to make an angled part conspicuous. The drainage pipe metal fittings 80 disposed on the back face 51 and the bridge pier metal fittings 90 disposed on the bridge pier 2 are covered with the extension portions 53 to prevent the exposure of these metal fittings, which also improves the appearance of the bridge pier drainage pipe.
