On October 24, the world's longest sea bridge Hong Kong-Zhuhai-Macao Bridge will be thrown open for traffic. This will be the world’s longest bridge with the 55-kilometer-long bridge, situated in the Lingdingyang waters of the Pearl River Estuary. In December 2009, the construction of the multibillion-dollar bridge had begun. It will slash the travel time between Hong Kong and Zhuhai from three hours to just 30 minutes, further integrating the cities in the Pearl River Delta. The bridge will be opened for traffic on October 24, the Hong Kong-Zhuhai-Macao Bridge Authority said. Earlier, lawmakers in Hong Kong warned that the bridge, which provides a direct link to Hong Kong International Airport, could bring extra traffic to Lantau Island, and cause congestion. The Transport Department has already capped the number of permits for cross-border private cars at 5,000. A government-commissioned study from 2016 estimated that 29,100 vehicles would use the bridge daily, by 2030, which was 12 per cent down from a report written in 2008.
