This bridge is almost as bad as the Brent Spence Bridge in Cincinnati but not that old. A Twin Structure ought to be built parallel to this one.

What is the rating of this bridge as of August, 2007. I have always been afraid on this one and the collapse in Minnesota has not helped.

There are no emergency pull-off lanes on this bridge. If a car stalls or stops for any reason, it stalls or stops in a traffic lane. There have been numerous crashes as a result of this deficiency. Many have resulted in fatalities. One crash, involving a DUI driver, sent a small child over the side of the bridge. He fell ~80' to his death.
