Value significance

Dongshuimen Yangtze River Bridge is a part of Chongqing Liangjiang bridge. The two bridges are connected with Yuzhong District, the mother city of Chongqing, and connect the South Bank district and Jiangbei District respectively. They are an important channel connecting the two sides of the Yangtze River and Jialing River. The opening of dongshuimen Yangtze River Bridge marks the addition of another shortcut across the Yangtze River in the core area of Chongqing's main city, which will shorten the distance between tanzishi CBD in Nan'an District and Jiefangbei CBD in Yuzhong District, and play a greater driving role in urban development. < I (China news online review) < / I
