Road traffic has long been an important means for transporting goods between Hong Kong and the mainland of China (the Mainland). In the past decade, the annual proportion of road cargo throughput in total cargo throughput ranged from 10% to 18%. Of the four boundary control points currently connecting Hong Kong and the Mainland, namely Lok Ma Chau, Man Kam To, Sha Tau Kok and Shenzhen Bay control points, Lok Ma Chau was still the busiest control point through which cargoes were transported, accounting for around 70% of the total road cargo throughput in 2009.

Feature articles addressing this subject have been published in this Digest regularly since 2001. This article provides a detailed analysis of the road cargo statistics in 2009.
