The Huangmaohai Sea-Crossing Passage, connecting Zhuhai and Jiangmen, officially opened on Wednesday, and it is expected the link will boost travel across the Greater Bay Area (GBA).

The 31-kilometre link is the western extension of the Hong Kong-Zhuhai-Macau Bridge, and starts in Pingsha Town while ending in Taishan City's Doushan Town.

The project consists of two main bridges - Huangmaohai Bridge and Gaolan Port Bridge, two tunnels, four interchanges and one service area.

With its commencement, the travel time between Zhuhai and Jiangmen is reduced from more than one hour to 30 minutes.

Local media reported that some drivers from different GBA cities, including Zhuhai, Jiangmen and Macau, waited to get a glimpse of the link.

Construction of the bridge began in 2020.

It is the world's longest three-tower cable-stayed highway design bridge.
