That's the Trestle Bridge on the High Trestle Trail near Madrid, IA. The whole trail is quite amazing; paved and separated from the highway.

The "reverse" would be an extra-ordinary, or high wheel safety, the first American designed bicycle. Mine is specifically called an Eagle (which originated from Springfield, Mass.). I felt much better flying down the 20% grade at Twister Hill on it than on an ordinary - it is so much safer going downhill (yet, much squirellier steering, uphill and bumps/rocks).
