The Weipu Bridge is a bridge from Weinan to Pucheng with a total length of 2377.08 meters. It is currently the longest bridge on the Weihe River and the most convenient way to enter Weinan from the north of the Weihe River. This project mainly uses about 4,800 sets of RGB wall washer lights, about 3200 sets of RGB flood lights, and about 8,500 sets of RGB point light sources. When the night came, the colorful changing effect and the symmetrical reflection in the water seemed to be a rainbow on the water, so that the night was no longer black, making the bridge vibrant.
