The Hong Kong-Zhuhai-Macao Bridge is not built on a straight line, and the shortest distance between points is due to the following two reasons: 1, the Pearl River Estuary is more than 30 kilometers wide, and the water flow directions in each section are different. From the engineering point of view, it is hoped that the axial direction of the pier and the direction of water flow are roughly flush, so as to minimize the water resistance. 2. If dozens of kilometers of bridges are built into a straight line, drivers will be easily tired and sleepy, and traffic accidents will easily occur. 2. How many kilometers is the Hong Kong-Zhuhai-Macao Bridge?
The total length is 55 kilometers. The Hong Kong-Zhuhai-Macao Bridge starts from the artificial island of Hong Kong near the Hong Kong International Airport in the east, crosses the Lingdingyang sea area in the west, connects the artificial islands of Zhuhai and Macao, and ends at Hongwan, Zhuhai. The total length of the bridge and tunnel is 55km, of which the main bridge is 29.6km, and the Hong Kong-Zhuhai-Macao port is 4 1.6km; the bridge deck is a two-way six-lane expressway with a design speed of100km/h; The total investment of the project is 654.38+026.9 billion yuan. 3. What is the use of the Hong Kong-Zhuhai-Macao Bridge?
1. Traveling between Hong Kong, Macau and Zhuhai, you don't have to go through multiple customs or traffic jams on the road to waste time. The driving time is directly shortened from three hours to about half an hour, and it can be directly inspected at an entry point. 2. Facilitate the economic exchanges between people and vehicles in the three places, effectively attract Hong Kong funds to invest in cities on the west bank of the Pearl River, and effectively promote the economic development of Macao, Zhuhai and even the west bank of the Pearl River. 4. How many years has the Hong Kong-Zhuhai-Macao Bridge been built?
From the establishment of the preliminary work coordination group office in March 2004, to the official start of construction on June 5438+February 15, 2009, and the official opening of the Hong Kong-Zhuhai-Macao Bridge at 9: 00 am on October 24, 2006, it took 14 from design to construction.
