More than 800 people attended the ceremony including representatives of the roughly 50,000 construction workers, engineers and designers from the Chinese mainland and Hong Kong and Macao SARs who built the bridge.

The top officials from Hong Kong, Guangdong, and Macao welcomed the opening of the bridge in their speeches at the ceremony.

They cited the bridge as an achievement that opens a new chapter for Guangdong, Hong Kong and Macao to consolidate their strengths and make new contributions to the nation's development. They vowed to strengthen cooperation under the framework of the Guangdong-Hong Kong-Macao Greater Bay Area.

Hong Kong Chief Executive Carrie Lam Cheng Yuet-ngor said the HZMB creates new vitality for Hong Kong's development. Its commissioning will expand the city's role from a "connector" to a more active "participant" in the country's overall development.
