8. Hong Kong-Zhuhai-Macao Bridge opens to traffic

The Hong Kong-Zhuhai-Macao Bridge, the world's longest sea bridge, officially began service on Oct. 24.

The 55 km-long bridge links China's Hong Kong Special Administrative Region (SAR), Zhuhai city of Guangdong Province and Macao SAR. It is the first large-scale infrastructure project jointly developed by Guangdong Province, Hong Kong SAR, and Macao SAR under the principle of "one country, two systems."

It serves as a strategic transportation hub linking the west and east of Guangdong-Hong Kong-Macao Greater Bay Area.
