This week’s Pic of the Week takes us to Iowa and to this bridge. The Thunder Bridge is one of two Pennsylvania through truss bridges that span the Little Sioux River in Spencer, Iowa. The bridge is the shorter of the two and also the younger, having a length of 164 feet and been built in 1905. Yet the two were built by the same company, the Clinton Bridge and Iron Works Company. They also have other commonality: the sound of rattling wooden planks when crossing it. In the car or even taken from an oblique angle like in this picture taken in 2011, one will hear it clearly. A video taken by another avid bridge fan and fisherman below will show you the sound taken from the car.
Currently the bridge is still open and if you want to get some photos, you can park at the nearby boat access next to the bridge. It’s highly unlikely that the bridge will close to traffic because only a few cars cross it daily. Furthermore, the street which the bridge carries makes a loop and ends a quarter mile to the west at the same highway, which makes truck deliveries easier. If anything, since Clay County has a few very unique but important artefacts, that Thunder will at the very most receive new wooden flooring in addition to the repairs of beams and the like, making it one of the classic examples of in-kind restoration, and one where the wheels will keep on rattling, just like in the pic with the US-Postal Service truck. A real treat if you visit Iowa and happen to pass by this place.
