It was learned that the yet-to-be-identified reporter alighted from a commercial bus conveying him and some of his colleagues to work and immediately dived into the lagoon.
According to witnesses, the journalist pretended that he wanted to urinate.
After the incident, operatives of the Rapid Response Squad (RRS) in Lagos rushed to the scene but could not rescue the journalist.
The corpse of the deceased was later retrieved through the support of local divers and reportedly taken to Ebute Ero police division.
Spokesman for the Lagos State Emergency Management Agency (LASEMA), Kehinde Adebayo, said efforts were being made to transfer the corpse to a mortuary.
The LASEMA spokesman said the agency would soon issue a statement on the development.
Late 2017, a medical doctor identified as Allwell Oji ended his life by diving into the lagoon from the bridge.
There have been different other cases of suicide on the bridge which connects the mainland part of the state to the island.
