Hangzhou Jiangdong Bridge lights up Yesterday evening, Hangzhou Jiangdong Bridge (Qianjiang Jiuqiao) officially lit up. Under the guise of the gorgeous lights, the four 65-meter-high main towers are shaped like the sails on the river, and in the form of traditional suspension bridges, the landscape of Qianjiang Fanying is outlined. The bridge will be officially opened to traffic this Friday, when it will be connected to Xiasha and Xiaoshan Jiangdong.
No light pollution
Will such a beautiful light produce light pollution and affect the normal driving of the driver?
When we designed the bridge lighting, we have considered the problem of light pollution. Zhu Kanglong, manager of the landscape project of Jiangdong Bridge, said that there are a total of 560 suspension cables on the Jiangdong Bridge, all of which are LED energy-saving lamps imported from the United States. There are more than 30,000 small lamp beads in the suspension cable. The power of each lamp bead is 1W, while the ordinary lamp bead has only 0.030.08W power. Such a large number of high-power LED energy-saving lamps have not been used in Hangzhou before. However, these energy-saving lamps are newly developed products, which can be regarded as the smallest light source, and thus will not affect the normal passage of drivers and pedestrians.
In addition, the sidewalk of the Jiangdong Bridge uses orange asphalt, which is the first attempt on public roads (previously used in stadiums, school playgrounds). Because black asphalt will be white for a long time, it will be more troublesome to maintain.
Jiangdong Bridge opened to traffic on Friday
The Jiangdong Bridge was officially opened to traffic this Friday. The west of the bridge connects the east line of Desheng Expressway and the north side of the lower reaches of Qianjiang Guanchao City in Xiaoshan. It is the first large-span suspension bridge in China. The bridge is more than 4,300 meters long. The main bridge consists of two steel suspension bridges similar to the Golden Gate Bridge in San Francisco, USA. The steel bridge is composed of bridges and the bridge deck is 47 meters wide. It is constructed according to the two-way eight-lane standard of the main road of the city. The design speed is 80 kilometers per hour. It is the widest bridge bridge in the mid-bridge of the Hangzhou Cross-river Bridge. After the bridge is completed and opened to traffic, it will connect Xiasha and Xiaoshan Jiangdong into one.
