On June 11, 2004, five different tornados were spotted in various parts of Clay County. My wife and I happened to witness the one that destroyed the old iron bridge, built in 1926, that used to span the river here. That tornado was 1/2 mile wide and stayed on the ground almost 10 miles to north of Webb, Iowa. The iron trestle bridge was picked up and laid on it's side, still intact, cross wise in the river, creating a dam. Shortly after arriving here, we and others witnessed the water pressure build up to the point that it slowly turned the bridge releasing the water. The present structure is a great improvement over the old 6 ton weight limit trestle bridge.
