Witnesses said the bus was heading to the mainland from Obalende bus terminus on Lagos Island when it was involved in a crash.
There was no information about what caused the crash.
But the bus was said to be mangled while a large quantity of blood was seen at the scene.
Traffic and rescue officials raced to the scene immediately after the crash and moved the dead and injured to nearby hospitals.
The crash caused a gridlock on the outward Lagos section of the busy bridge.
