This is an incredible and beautiful bridge--even sitting in place, it looks like it's actually bounding across the river! The arches give it a very graceful appearance.

Damn if I wasn't right on. I read your comment Tony and immediately thought of the Oregon Caves, just down the road a piece. Sure enough. This link confirms it. Good luck Tony and Michael.

This is an amazing span.....or another "McCullough Masterpiece"....if you will!

Michael, do you happen to know how the bridge got it's name?
