A popular Lagos prophet has strongly warned motorists and pedestrians to vacate the Lagos Third Mainland Bridge between the hours of 7:00pm and 11:00pm on Friday 27th of August 2010 as a terrible disaster that would fill all headlines would occur. There is a high probability that this prophecy would not come to pass but there is really no harm heeding the warning, if possible, albeit a spiritual one. An accident happens in a few seconds meaning people should avoid the bridge as soon as the Sun disappears and just before midnight, 6:30pm to 11:30pm might be closer then.
I expect the 3MB to be very free tonight then as many "spiritual" people will try to avoid the bridge so leave the Island around 6:25pm and you'll be good with the bridge. Anytime from 7:00pm and the bridge will become another Auto-Bahn

My advice: follow your instinct.
