Traffic over the Hong Kong-Zhuhai-Macao Bridge hit a peak on Saturday and Sunday, the second weekend after the northbound travel for Hong Kong vehicles program took effect on July 1.

According to border inspection station, more than 9,300 vehicles from Hong Kong and Macao entered or left the mainland via the bridge on Sunday, the most in a single-day since the beginning of the year.

It was the 7th time the bridge, which connects the three cities of Hong Kong, Zhuhai and Macao at the mouth of the Pearl River, hit a traffic peak this year.

The fast travel mode and convenient customs clearance environment are inducing an increasing number of Hong Kong residents to cross the bridge to visit Guangdong, according to a statement released by the bridge's border inspection station.
