Why Continuous Pilling Of Asphalt On Third Mainland Bridge Is Unsafe – Umahi

Third Mainland Bridge

“You see, each carriageway of the Third Mainland Bridge is 14 metres which means that each carriageway is two standard carriageways. So, we are dealing with 14 carriageways. What has happened is that in engineering design, there is what is called a dead load and the asphalt is a dead load. What that bridge [design] is meant to carry is two inches of overlay asphalt,” he said during the show.

“But over the years, in the course of maintenance, when a portion of it is scratched, what will happen is that they will come and clean it up and put another asphalt on it. So, we have an asphalt thickness of between four and twelve inches. So, if you are riding on that Third Mainland Bridge, you will see that you are on a superelevation and that is dangerous. It can cause overturning. And again, it [Third Mainland Bridge] is not designed to carry that dead load.”
