As the first river-crossing tunnel constructed in Taizhou, the Jiaojiang Jiefang Road River-Crossing Tunnel is part of the expressway network in the urban backbone road network structure, and is of great significance for improving the road network system of the Taizhou urban area and optimizing the urban spatial layout. Since the start of construction, the project has attracted attention from all sectors, and all builders have tackled difficulties and worked around the clock to ensure that the project progresses on schedule.

Recently, at the construction site of the Jiangbei section of the Jiaojiang Jiefang Road River-Crossing Tunnel project, hundreds of workers are working on the front line, carrying out operations such as foundation pit crown beam construction, rebar tying, and pile foundation construction, making preparations for the subsequent foundation pit excavation.

The Jiaojiang Jiefang Road River-Crossing Tunnel project is divided into three parts: the Jiangbei section, the river-crossing section, and the Jiangnan section, among which the river-crossing section is the controlling node of the entire project. At present, the workers are racing to advance the construction progress of the retaining structure of the shield launching shaft in the river-crossing section, laying a solid foundation for the shield construction of the river-crossing section in the first half of next year.

The workers are racing to advance the construction progress and plan to complete the main structure construction before the Spring Festival. After the shield machine is lowered into the shaft and assembled and debugged, construction of the river-crossing section will begin.

The Jiefang Road River-Crossing Tunnel project has a total investment of 4.032 billion yuan. It starts from the south side of the intersection of Zhang'an Avenue and Daluo Road in Jiaojiang in the north, runs southward along Daluo Road, crosses beneath the Jiaojiang River in the form of a shield tunnel, and then runs southward along Jiefang Road. The main tunnel is cut off and buried on the north side of the Haimen River, with conditions reserved for the later southward extension of the tunnel, and entrance and exit ramps are set up near Jiaobei Avenue, Gongren Road, and Phoenix Park. The route has a total length of 4.3 kilometers, of which the shield tunnel is 1,822 meters long and the cut-and-cover tunnel is 2,398 meters long. The main line of the river-crossing shield tunnel section adopts dual-direction six lanes, and the main line of the cut-and-cover tunnels on both banks adopts dual-direction four lanes plus emergency stopping lanes.

Since the project started construction at the end of December 2023, the construction party has promptly solved difficulties encountered during construction, such as ultra-deep and ultra-wide foundation pit construction in soft strata and the relocation of extremely large pipelines, and has carried out scientific construction to fully advance the project construction. Up to now, the north bank of the project has completed the construction enclosure from Qianzhang Road to the west side of Jiaobei Avenue, and the south bank is carrying out foundation pit trench wall reinforcement construction within the scope of the shield tunnel receiving shaft. After the project is completed, the travel time from Shizi Road on the south bank of the Jiaojiang River to Qiansuo on the north bank will be shortened from the current 25 minutes to 5 minutes, greatly facilitating transportation for residents on both banks of the Jiaojiang River.

The project is planned to be completed and opened to traffic by the end of 2027, and will become a key channel for north-south traffic connection across the Jiaojiang River. This project is also a north-south expressway in Taizhou's urban road network plan, and the completion of the expressway will play a key role in promoting the integration of urban and rural areas.
