Recently, the last underwater bearing platform of Yongning Bridge in Ruian City has been poured. This means that the large-scale concrete construction stage of Yongning Bridge in the water has been completed, and it has entered the visual construction stage above the water surface, laying a solid foundation for the next pier construction and bridge closure.

Accompanied by the roar of the machine, several cement mixers continue to work alternately, continuously transporting concrete to the sky pump, and using the long arm of the sky pump to inject concrete into the last water bearing platform.. Recently, the last underwater bearing platform of Yongning Bridge in Ruian City has been poured. This means that the large-scale concrete construction stage of Yongning Bridge in the water has been completed, and it has entered the visual construction stage above the water surface, laying a solid foundation for the next pier construction and bridge closure.
It is reported that the bearing platform is 48.5 meters long, 15.5 meters wide, 5 meters high and 425 tons of steel bars, which is the largest underwater bearing platform in the project. Nan Fei, deputy project manager of the Yongning Bridge built by Zhongjiao Road, told the reporter: "There are nine piers in the main bridge of the Yongning Bridge in the water, two piers on the shore, and seven piers in the water. Pier No.5 is the last bearing platform to be poured in the seven piers in the water, and it is also the bearing platform with the largest earthwork volume. This time, more than 2,100 cubic meters were poured."
Urban Railway Line S3 starts from Wutian Station in Ouhai District, passes through Nanbaixiang, Xianyan and Tangxia, and ends at Feiyun Station in Ruian City, with a total length of 33.2 kilometers. As a control project of Line S3, Yongning Bridge is located in the sea area between Feiyunjiang Bridge and Feiyunjiang Third Bridge on National Highway 104 in Ruian City, near Ruiguang Avenue on the north bank of Feiyunjiang River and Weiwu Road on the south bank of Feiyunjiang River. The bridge is about 3.1 kilometers long, of which the river-crossing area is about 1.1 kilometers long, with a total investment of about 4.05 billion yuan. It is a multi-functional and complex river-crossing channel integrating three traffic functions of municipal railway, expressway and first-class highway. It is the first key project of "high-quality development and construction of common prosperity demonstration zone" in Zhejiang Province. It is also the largest span multi-tower rigid suspension bridge for both highway and rail in China so far. The project connects the main urban area of Ruian and Jiangnan New Area, and will further optimize the layout of the river-crossing channel in Ruian after completion.
Not only that, another key project in Ruian City also received good news. Tingtian Depot of the first phase of Wenzhou Regional Railway Line S2 has successfully completed track laying recently, which marks the completion of all track laying construction tasks of Line S2 and creates good conditions for subsequent rail welding operations and fine adjustment of the line.
It is reported that Tingtian depot mainly undertakes the work of S2 line vehicle parking, cleaning, inspection and maintenance, including 29 lines such as parking train inspection line, car washing line, traction line and test line, with a total length of 9.55 km. The completion of this project will contribute to the smooth connection of Line S2 and accelerate the formation of the urban transportation network in Wenrui Plain.
