Traffic resumes on South China sea bridge
GUANGZHOU -- Traffic resumed Friday morning on a sea bridge in South China's Guangdong province after it was temporarily closed last week due to abnormal shaking.
On May 5, two-way traffic restrictions were placed on Humen Bridge linking provincial capital Guangzhou and the city of Dongguan as a safety measure after it began to shake amid severe winds.
Experts were sent to the site to conduct thorough examinations, tests and safety evaluations. They also discussed ways to stop the shaking.
After evaluations, the experts found that the bridge's structure and function were in good condition, and that the shaking did not cause abnormalities in the bridge.
Under specific wind conditions, vortex resonance caused the bridge to shake, according to the experts. Authorities have taken a variety of technical measures to stop the shaking, and the measures are working well.
The Humen Bridge spans about 16 km. It is a suspended bridge.
