Today, the Changhai Bridge project, the largest cross-sea bridge project in Northeast China, was officially launched in Dalian, Liaoning. The project is an important part of National Highway 507, with a total length of 25.5 kilometers, including a 19-kilometer cross-sea section and a 6.5-kilometer land section.
Among them, the cross-sea section is about 19 kilometers long. It enters the sea from the east side of Yuanyang Port, Dachangshan Island, Changhai County, Dalian, crosses the Lichangshan Strait, and lands on the east side of Pikou Port, Pulandian District, Dalian.
The total investment of the project is about 7.9 billion yuan. The entire line adopts first-class highway technical standards, with four lanes in both directions and a design speed of 80 kilometers per hour. It is planned to be completed and opened to traffic in 2030.
By then, the traffic dilemma of "going from morning to night and looking at the sky and leaving the island" in Changhai County, the only island border county in the country, will be solved.
As a reserved cross-sea channel of the National Highway G507, the Changhai Bridge is an important part of the National Highway G507. It is the mainland-island highway project with the largest investment scale under construction in my country, the only mainland-island bridge in an island border county in my country, and the longest cross-sea bridge project in Northeast China.
The design of the Changhai Bridge takes the "water drop shape" as the main creative line, implying Dalian's city concept of living on, thriving on, and prospering from the sea. The bridge towers are like dripping water, nourishing the Changhai. It is magnificent and will become a new landmark of the city.
