> My experiences with bridges have been mostly on school trips, with the kind of highway bridge you describe. I never gauged the length, but they seemed pretty big. Outside of such trips, I have crossed from Hamilton, IL to Keokuk, IA on a bridge. Other than the statue of the city's namesake, there wasn't much new about it.

In some ways, covered bridges are the most interesting type. The original idea was to keep rain and snow off the wooden deck to prevent rot. The few that are left have become tourist magnets. We see them as a picture waiting to be taken.

New England is probably the best area to look for covered bridges, but I have seen them in a number of southern states. I haven't looked, but there is likely to be a listing of covered bridges on the internet.
