Yiwu Shugang Expressway starts from Hangjinqu Expressway, passes through Houzhai Street, Suxi Town, Industrial Park, Choucheng Street and Ersanli Street, and finally ends at Jinyong Expressway. Main line 2 1.659km, design speed 100km. The main line Houzhai Hub is located between Pujiang and Yiwu Interchange of Hangjinqu Expressway. Houzhai Hub and Humen Interchange are designed as a two-way four-lane expressway with a subgrade width of 26 meters, and the hub from Humen Interchange to Terminal 23 is designed as a two-way six-lane expressway with a subgrade width of 33.5 meters. Engineering construction is difficult, and there are many large-scale interchanges. * * * There are 6 interchanges with high bridge-tunnel ratio, accounting for 86.3% of the engineering quantity. The project needs to cross the Hangzhou-Changzhou high-speed railway and the Shanghai-Kunming railway, and the construction requirements are high. After the project is completed and put into use, it will be incorporated into the national expressway network and unified expressway management will be implemented. This is the first time that Yiwu has adopted BT mode.
There are four ramps connecting Hangjinqu Expressway in Houzhai Hub, and two of them cross Hangjinqu Expressway. In view of the fact that the section from Hongken to Jinhua of Hangjinqu Expressway is currently in the widening construction stage, and the section from Paitou in Zhuji to Shangxi in Yiwu will be closed from June 6, 2006 to September 28, 2005, the expert group suggests further optimizing the time nodes of two ramps crossing the bridge to ensure that the two ramps are completed during the widening and closing period.
The implementation of Yiwu Shugang Expressway project will effectively crack the traffic bottleneck in Yiwu urban area, guide logistics to "leave the city" quickly, and accelerate the construction of Yiwu dry port city. After completion, Yiwu Port-Shu Expressway will not only have the function of "Yiwu Port", but also serve as a link between Hangjinqu Expressway and Jinyong Expressway, which will help ease the traffic pressure in Yiwu urban area and related provincial highways, and is of great significance for building urban agglomerations in central Zhejiang and enhancing Yiwu's external economic radiation.
