The number of inbound and outbound single-plated vehicles, or vehicles only registered in one of the Hong Kong and Macao special administrative regions, passing through the bridge, exceeded 2 million as of March 24.

Since the implementation of policies to allow single-plated vehicles to head north into the mainland through the bridge early in 2023, the number of inbound and outbound passenger vehicles passing through the bridge has increased significantly.
