Third Mainland Bridge Is Vibrating?

Here's what an eyewitness posted after passing the bridge this morning:

Driving to work this morning, I witnessed a very scary scene at the 3rd Mainland Bridge in Lagos. The traffic was moving at a snail's pace as usual, when suddenly I was jolted by a sharp and tremendous vibration. I looked out and noticed that I was atop an expansion joint. What scared me most was that one side of the joint was noticeably vibrating. What I mean is that you could see one part swinging up and down. This happened at exactly the joint where the Lagos bound traffic from Adekunle meet the traffic from Oworoshonki. I was too shocked to take photos/video, perhaps if i have the courage to pass through there
tomorrow i will do so.
