New progress was made in the construction of the Shenzhen-Zhongshan Bridge's west artificial island on October 27. After about 14 hours of continuous construction, the last ramp on the island was successfully completed, marking the completion of the main structure of the cast-in-place tunnel on the island.

From above, the kite-shaped outline of the west artificial island is clearly visible, and the five ramps are located in the middle of the island similar to the shape of a fork.

The cast-in-place tunnel of the west artificial island plays a critical role in the connection between the bridge, island and tunnel, and the five ramps are vital to the interconnection of the island. Vehicles can reach the bridge, tunnel and island areas through the five ramps.
