The “circle” of the Fourth Ring of Wuhan is just around the corner, and Wuhan will welcome another important ring project. On December 7, the Wuhan City Circle Grand Corridor began construction of the Shuangliu Yangtze River Bridge of the Xingang Expressway.
The Wuhan City Circle is located between the Wuhan Ring Highway and the Wuhan City Ring Highway, with a total length of about 360 kilometers. It starts at Huangpi in the north and passes through Huanggang Hongan and Xinzhou in a clockwise direction. Shuangliu Yangtze River Bridge is set up to cross the Yangtze River and pass through Ezhou Huarong, using Huang-E Expressway, E-Xiang Expressway, passing through Ezhou Liangzi Lake, Jiangxia, Xianning Jiayu, establishing the Yangtze River Bridge in Leizhou Bay on the Yangtze River, passing through Hannan, Caidian, Xiaogan Hanchuan, Yunmeng, Xiaonan and entering the Huangpi Formation All the loop.
Xingang Expressway is an important part of Wuhan City Circle, it starts at S111 Hanxin Line in Xinzhou District, Wuhan, passes through the Yangtze River and establishes the bridge over the Shuangliu Yangtze River. The implementation of the Xingang Expressway is of great importance to improve the design of the Wuhan City Circle road network and accelerate the integrated development of Wuhan City Circle transportation.
The Shuangliu Yangtze River Bridge of the Xingang Expressway is the twelfth Yangtze River Bridge in Wuhan. The main bridge is planned to adopt the 8-lane two-way highway standard with a design speed of 120 km / h and a subgrade width of 41.5 meters; The connection plan is to adopt a standard two-way, six-lane highway with a design speed of 120 km / h and a subgrade width of 34 meters. The main bridge of the Shuangliu Yangtze River Bridge adopts a steel truss suspension bridge structure, which is the widest steel truss suspension bridge in the Yangtze River.
The start of construction of the Wuhan Metropolitan Corridor is of great importance to improve the modern transportation system of Wuhan.
At present, Wuhan is gradually forming a high-speed road network with “circle + radiation” as the main skeleton. In terms of ring lines: the first ring is the central area traffic distribution ring; the second ring is the central urban rapid transport transmission and distribution ring; the third ring is the rapid transition ring between the main urban area and the six new city groups; the fourth ring is the traffic between the six new city groups Logistics Highway Loop Line; Wuhan Ring Expressway is an urban transit highway loop line; Wuhan City Circle Ring Expressway is an integrated urban circular transportation expressway loop line.
“However, the road network still has problems, such as insufficient radiation in some directions and poor conversion of the loops. It needs to be further optimized, expanded coverage, improved road network capabilities and benefits scaled.” The “Key tasks for the construction of new developments in 2019” of the National Development and Reform Commission on “Large cities actively promote the spread of industries and populations to the one-hour roundabout”, according to the requirements related to the “Ten major projects in Hubei Province after the epidemic of rejuvenation and strengthening deficiencies. ” The goal of the “Three-Year Action Plan (2020-2022)” requires Wuhan to begin construction of the Wuhan City Circle at the right time.
Tong Yaxiong, deputy director general of the Wuhan Comprehensive Transportation Research Institute, introduced that after the completion of the Wuhan City Circle, the central transportation structure of the Wuhan City Circle, the “transportation circle of 1 hour “, giving full play to the strategic role of” strengthening the interior and bringing the surrounding areas into play. ” It will effectively support the construction of Wuhan as a national core city, accelerate the construction of Wuhan urban development zone, support and guide Wuhan urban spatial expansion, industrial transfer and population migration, promote the development of the urban circle of Wuhan, will further optimize the structure of the national high-speed network in the Wuhan urban circle and strengthen the ring line. Channel the supply capacity, strengthen the connection and conversion of the road network and build a central city for comprehensive transportation.
It is understood that during the period of the “14th Five-Year Plan”, Wuhan will coordinate the newly built highway with a mileage of about 330 kilometers and a total investment of nearly 100 billion yuan. After the completion of these projects, the mileage of highways in Wuhan will exceed 1,200 kilometers, and the density of the road network is expected to enter the top 3 of the 15 sub-provincial cities.
