On August 19, 2022, Zhejiang Provincial Public Resource Trading Center released the public announcement of the survey and design survey and design bid opening record of the Yiwu-Longquan section (Jinhua section) of Yilongqing Expressway. The estimated total investment of the project is about 37.22 billion yuan, and the construction and installation cost is about 21.51 billion yuan. Yuan. The planned construction period is 2920 days.

Project Overview

The starting point of the Yiwu-Longquan section (Jinhua section) of Yilongqing Expressway is located at the G1512 Yongjin Expressway Xucun Interchange, passing through Jiangdong Street, Fotang Town, Chi'an Town in Yiwu City, Huashui Town in Dongyang City, and Tangxian in Yongkang City Town, Xiangzhu Town, Xicheng Street, Huajie Town, Baiyang Town, Quanxi Town, Shuxi Street, Wangzhai Town, Yuyuan Township, Taoxi Town, Tanhong Township, Xilian Township, Liucheng Town, etc. A long tunnel is set up to reach the territory of Lishui, finally at the junction of Wuyi and Suichang, and then to the Lishui section of Yilongqing Expressway. The total length is about 105.473km, of which about 16.013km within Yiwu, about 1.94km within Dongyang, about 29.562km within Yongkang, and about 29.562km within Wuyi. 57.958km. The main line of this project is about 22.7km of synchronous construction connection line.

The design speed of the main line of this project is 100km/h. The section from the starting point to the Wuyi Wangzhai hub adopts the two-way six-lane technical standard, and the width of the roadbed is 33.5 meters; Two-way four-lane technical standard, roadbed width 26.0 meters. There are 2.5 hub interchanges on the whole line, of which the starting point is a composite hub. The hub intersects with Yongjin Expressway and connects Huancheng Road and Choufo Road with a ramp; Yongkang North Hub is jointly built with the Yongkang connection line of Yilongqing Expressway. , this project only counts the ramps that drive out of the project, the scale is calculated as 0.5, and there are generally 10 interchanges. The total length of the main bridge is about 36876m/91. There are 10.5 tunnels, and 0.5 of the tunnels at the junction of Yiwu-Longquan section of Yilongqing Expressway are included in the scale of the project. The total length of Niutoushan tunnel is about 10190m, and the inner length of Jinhua section is about 5649m. About 7833m, it is a two-hole six-lane split tunnel, with a total of about 24922m; the bridge and tunnel accounts for about 58.6% of the whole line. Facilities along the line include 2 service areas, 1 parking area, 11 toll stations, 1 management sub-center, 1 maintenance area, 3 tunnel management stations, 1 high-speed traffic police room, and 1 expressway road administration room. The specific structure setting is subject to the final approval. Key words: engineering construction information, engineering news, engineering construction
