I know. All that bridge needed was approaches, railings and a bike-friendly deck. Everything else was fine; I rode over it before it was removed. Of course, no one would likely sign up for the safety of the structure years and years (decades) after it was last used.
The other bridge that might be useful is the one that crosses the main traffic lanes of I-30. It's blocked off but still intact. There would need to be provisions to cross the access roads though, so maybe not very practical. (I crossed that bridge too, which wasn't blocked off at that time).
