Customs clearance between Macao and Zhuhai will be carried out on a "Joint Inspection and One-time Release" principle, in order to make the process efficient for travellers using the Hong Kong-Zhuhai-Macao Bridge. Under the new customs system, travellers will be required to pass border controls only once via either the automatic, semi automatic, or manned channels depending on the identification documents to complete the departure and arrival formalities. The bridge will start operation on Oct. 24, further integrating cities in the Pearl River Delta.
