The Yangpu Bridge was opened to traffic in 1993. It has a total length of 7654 meters and a span of 602 meters. The main bridge is 1172 meters long and 30.35 meters wide. For the project, approximately 400 sets of C0820-QR LED street lights and over 500 sets of tunnel lights were installed to illuminate the bridge, and existing landsacpe lights were upgraded to modern LED technology. In this way, the city cuts its power overheads by around 50% compared to the old system– the quality of light is also significantly improved.
