Where is the main bridge of Humen Bridge? What happened to Humen Bridge?

1. Humen Bridge is a sea-crossing bridge connecting Nansha District, Guangzhou City, Guangdong Province, China and Humen Town, Dongguan City. It is located on the Lion Ocean in the Pearl River and is a part of the south connecting line of the Pearl River Delta Ring Expressway (formerly Guanfo Expressway).

2. Humen Bridge1started on October 28th,1992; It was completed and opened to traffic on June 9,1997; It passed the completion acceptance on April 20th. 1999.

3. Humen Bridge starts from Dongguan Taiping Interchange in the east, crosses Shiziyang Estuary in the upper part and reaches Guangzhou Nansha Interchange in the west; The total length of the line is 15.76 km, and the total length of the main bridge is 4.6 km. The bridge deck is a two-way six-lane expressway with a design speed of120km/h; The total investment of this project is 3.02 billion yuan.

4. On the afternoon of May 5, 2020, the Humen Bridge shook abnormally, and the whole bridge section was completely closed in both directions, and no traffic was allowed; On May 6, 2020, Guangdong Communications Group reported that the vibration system of Humen Bridge was vortex vibration, and the suspension bridge was structurally safe. According to the preliminary judgment of the expert group, the main reason for this vibration of Humen Bridge suspension bridge is that water horses are continuously arranged across the bridge along the guardrail under specific wind environment conditions, which changes the aerodynamic shape of the steel box girder and produces bridge vortex vibration under specific wind environment conditions. As of May 6, 2020, the water horse has been evacuated and the vibration amplitude of the bridge has been weakened. The deck of Humen Bridge has basically returned to normal.

5. As of May 7, 2020, Humen Bridge still had slight vibration, and the time for resuming traffic has not yet been determined. The maintenance unit is ready to organize bridge overhaul. On May 7th 16: 30, the navigable waters of Humen Bridge resumed navigation.
