Structurally, the bridge is fine. But it is functionally obsolete. Twice as many vehicles cross over it than what it was originally designed for. It should have at least two more lanes each way with wider lanes if it is going to be in the same location (though you can easily make the argument of putting it farther west, but that would take rerouting all of I75 through the area).
I only cross it when visiting my brother in Covington. But whenever I come home from Illinois I have to deal with the congestion that the bridge causes, especially near rush-hour.
