Whacky Bridge of Death

There is a bridge I cross each day that is insane - The Berkeley Bridge over the Elizabeth River in Virginia.
Here is the situation:
Approaching the bridge from the South [and connecting exactly at the bottom of the bridge] is an on-ramp from a check/weigh station, 2 lanes of North bound traffic from a freeway and 3 lanes of North-bound traffic emerging from a tunnel.
All these hit the 3 lane bridge at the same time... who designed this?.
The constant movement of cars ON the bridge itself explains all chaos theories - because despite the insanity, there are rarely accidents and everyone seems to get where they are wanting to go.
People on the left seem to all want to be on the right [for exits I'll get to] and people on the right want the opposite... no one wants the middle because just past the top of the bridge is one of those plastic and metal smashing posts that helps you choose a direction.
Anyway...
Where was I... Oh yeah....
Should you choose to go RIGHT you have 2 lanes that soon merge into 4 headed East.
Should you choose to go LEFT you have 2 lanes with an option to peal off to the right for a loop-around under toward the West. The 2 lanes that continue forward are greeted with a traffic signal within a few yards as your entrance into the city.

I am sure there are worse situations out there... but for the life of me I can't think of one.
