The reality of the situation is this: If you have an accident on a six-lane bridge then the best you can hope for is one clear lane to travel through on the side of the accident (and you don't always get that). If you think three rush-hour lanes lanes trying merging into one is going to be a walk in the park then you're sadly mistaken. The overall impact on people is going to end up being in the same ballpark once you account for the fact that more people will be regular users of the six-lane bridge compared to those who would have used a four-lane bridge.
Accidents happen and they cause traffic havoc, period - no matter how many lanes you have - unless you wildly overbuild beyond the capacity of the surrounding road network to supply traffic, which is a colossal waste of money IMHO.
