November eighth，It is invested and constructed by Changsha Traffic Investment Holding Group Co., Ltd.，Undertaken by CCCC First Highway Engineering Group，Changsha Xinglian Road Grand Passage Project participated by Liugong Owim Company，The hoisting of the steel girder of the main bridge mid-span closure section was successfully completed.，It marks the key control project of the project.-Closure of Main Bridge of Double-Tower Cable-Stayed Bridge。At this point，The project runs through the whole line.，It will be open to traffic by the end of the year.。

Xinglian Road is located in the north of Changsha City.，Across Wangcheng District and Kaifu District，Total length of project route 5.475Km，The main bridge across the Xiangjiang River is a double-tower cable-stayed bridge.，Span(165+380+165)m，It is the municipal cable-stayed bridge with the largest single investment in Hunan Province.。The width of the bridge deck is 38.5 meters，Set up two-way eight lanes，It is the widest bridge under construction in Changsha.、Maximum single span、The longest bridge across the river。The main beam is adoptedPKType of separated double-box steel-concrete composite beam，A total of 77 beam segments，Setup 4×17 pairs of parallel wire stay cables。The stay cable shall have a nominal diameter of 7mmHigh strength of zinc-plated aluminum alloy、Low-relaxation parallel steel wire stay cables，Standard tensile strength of steel wire is 1860MPa，Commonly usedPES7-163、PES7-199、PES7-223、PES7-253、PES7-283、PES7-313 and other six specifications。The net weight of stay cable steel wire of the whole bridge is 1295 tons.，The finished rope weighs 1495 tons.，It is manufactured by the Hubei base of Owim Company.，The installation of stay cable is carried out by Owim Engineering Company.。

Production of stay cable、The installation and construction lasted 8 months.，During this period, various difficulties were encountered.，If it has lasted for 1 month 40℃Above high temperature weather;Main beam could not be delivered due to flood season，A large number of delays in construction;Field processes are staggered，Difficult construction organization, etc.。Overeem employees are United，Improve the process，Careful planning，Deliver the goods according to the schedule and complete the hanging operation on schedule.。

After the completion of Changsha Xinglian Road Grand Passage Project，The road network structure of Changsha will be further improved.，Effectively alleviate the traffic pressure of the North Second Ring Road in Changsha，And become Yiyang、Changde and other cities are one of the important channels connecting Changsha.。
