The standard of the Hong Kong-Zhuhai-Macao Bridge (HZMB) project is to connect Hong Kong, 

Macao and Zhuhai, which are three economically active city clusters, and to create a fast communication

 channel in the east-west direction through the construction of a cross-sea bridge and an artificial 

immersed-tube tunnel in the Lingdingyang Sea, which will greatly shorten the passage time of these 

three regions and provide a strong impetus for the further development of the Pearl River Delta (PRD) 

region's economy, with the completion and official commissioning of the full route of the HZMB in 2018,

 after the completion of the whole line and officially put into use, many people found that there was no 

large-scale growth in the passage of vehicles after the completion of this bridge, so after the Hong

 Kong-Zhuhai-Macao Bridge was repaired, due to the lack of vehicles, it was regarded as a face-saving

 project by many Western countries, and it was only a way for China to show off its infrastructure strength to the world.

The reason for this situation, but also need to specifically analyze the specific situation, from the Hong Kong-Zhuhai-Macao 

Bridge after the completion of the use of the requirements, and other domestic high-speed road is different, due to this road

 connects two special areas of Hong Kong and Macao, and the mainland in the road vehicle driving standards there are differences,

 want to pass on the bridge in addition to the necessary documents, but also need to be in the three regions in the passes, currently 

has this kind of Passes and cross-regional exchanges of demand is not much, so overall the bridge construction of the initial road 

traveling the number of vehicles is not much, but in recent years the statistics have shown that the Hong Kong-Zhuhai-Macao Bridge 

passage of vehicles has been presented every year hundreds of thousands of times the growth trend, so it's too early to say that the

 Hong Kong-Zhuhai-Macao Bridge lack of traffic flow!
