This is probably the only thing that could work at the 11foot8 bridge https://www.youtube.com/user/yovo68/videos

I was just thinking, why don't they install a steel beam at the same height as the maximum allowed, like 11foot8?

Obviously it would be set much farther back than theirs.

because it might get knocked off into neighboring traffic.

Seems like a simple solution. Split the beam in the middle with hinges on left and right. Allow left and right beams to travel a bit but not too far.
