The Jintang to Dasha section project will start construction in 2022, and the overall project is planned to be completed in 2030. The Ningbo-Zhouzhou Expressway double-track Ningbo Qijiashan to Zhoushan Jintang section, which was approved for this construction, is about 18 kilometers long. The Jintang Undersea Tunnel of the key project is 11.6 kilometers long and uses 16-meter-level shield construction technology. It is currently the longest undersea highway shield tunnel in the world. The approval of the work means that we have taken another important step towards the start of construction. Jin Chaoyang, general manager of Zhejiang Transportation Groups Ningbo-Zhou Expressway Phase II Project Company, said that he will make every effort to promote all preliminary work of the project and strive to start construction as soon as possible.
