Little Niangua Swinging Bridge

Posted June 6, 2006, by Brian Roos (dragon8warrior [at] gmail [dot] com)

This bridge is about 25 minutes from where I work. It’s a very nice example of a self-anchored swinging bridge. It is 2 lanes and looks very sound, but does have quite a bit of rust on the metal. The deck is a metal grate deck with no concrete surface. It’s neat below the bridge because all the light shines through the deck. It’s also very loud when you drive across it. I will send some pictures to the website soon.
