Dashu Old Railway Bridge was built in 1911 and crossing the Gaoping River at 1526 meters. It was Asia’s longest bridge. In 1987, the railway went electric and the bridge was subsequently replaced. Homes and factories in the area polluted the river severely. In 2002, the city government launched an eco-restoration program, to develop artificial ponds, natural wetland plants, micro-organisms and a water purification system. Dashu Old Railway Bridge then became the biggest men-made wetland park in Taiwan and a dynamic attraction. The 120 hectares of wetland now include 10 water purification ponds. These ponds are kept particularly clean and a great location to watch the sunset reflect off their sparkling waters.
