In addition to the large-scale use of LED energy-saving lamps in the tunnel section, a large number of LED lights are installed on the bridge section of the Yangtze River Tunnel Bridge to form a landscape on the Yangtze River in the night. It is reported that the blue and yellow color LED lights are installed on both sides of the bridge with a total length of about 10 kilometers. The two kinds of light belts are intended to embody the geographical position of the bridge "Jianghai City".
