The Tappan Zee is rated at 3.708 (7 is the best, 1 is the worst). See page 3 of this PDF.The special was called "The Crumbling of America". Another bridge covered was even worse than the Tappan Zee. The Dover Bridge in Idaho received a sufficiency rating of 2 out of 100.
I also watched this History Channel special. While I didn't detect any out and out lies, I think that they sensationalized the issue.
