The Putuo Bay Tunnel will be officially opened to traffic at 00:00 on October 1. The reporter recently "explored the road" for everyone under the leadership of the engineering personnel, and it took only 5 minutes to reach Lujiayu from Donggang driving through the tunnel.

On the morning of the same day, the reporter came to the side of the east port of the tunnel. Looking up, the white steel structure of the cave door was seen. The five stone carvings of the "Putuo Bay Tunnel" were standing next to the tunnel entrance and export; The lighting lights on both sides of the cave are neatly arranged, and the entire tunnel is shining, as if extending a beautiful light band to the bottom of the sea.

The Putuo Bay Tunnel is connected to Donggang Haizhou Road and Lujiayu. The speed limit of the tunnel is 60 km/h. It is designed as a separate two -way four -lane and two lanes in the north and south lines. In the meantime, the vision is wide. Ma Zhengyin, the person in charge of the project, told reporters that the entire tunnel was arc and below the sea level. Nevertheless, we did not obviously feel downhill and uphill during driving experience. In addition, the two tunnels were installed with a total of 12 internal circulars to induced the smoke in the tunnel in real time. The air circulation was very good.

"The Putuo Bay Tunnel is the first highway shield tunnel in Zhejiang Province. The tunnel construction uses processes such as bright excavation, dark digging and shield method. In the uplift area, the craftsmanship is very complicated. "Ma Zhengyin introduced that the total investment of the project was 1.127 billion yuan, and the total length of the line was 2225 meters. The entire project adopts the "Underwater Shield Tunnel+Shanling Tunnel" solution, which was sent out from the Lu family. After passing through the fishing port, it reached the Shenjiamen gate.

On the open section of the Lu family side, on the walls on both sides, the workers are drawing the walls of Putuo with hand -painted walls and green eyebrow sailing boats jumping on the wall.

In addition, the 10 kV Chenhui Street switch station that guarantees the supply of tunnel power has been put into operation recently. "We strictly build the Chenhui Street switching station in accordance with the standards, and strictly control the construction and switching station's civil construction, electrical construction, etc. to ensure that the regional power grid engineering zero defects are put into operation."

After the Putuo Bay Tunnel is opened to traffic, it will become the third large channel to communicate with the Lujiazhang and Putuo City. For the traffic congestion of the Lujiazhong Bridge and the Donghai Road of Shenjiamen, drive the development of Lujiazan, and create the Shenjiamen and Lu family. " "One Hong Kong Cross -Strait" has a positive role in promoting.
