A well-designed bridge is a thing of great beauty, a soaring testament to the possibilities of engineering, but even if they don't particularly excite you of themselves, perhaps you'd like to contribute to this thread with songs that mention bridges, famous bridge scenes in movies, a funny thing happened to me on a bridge once etc.
^ This bridge is very attractive, and is a huge improvement on the previous design on the same site. Watch the short construction-nerd video and perhaps you'll be inspired to post a bridge you like too.
