Description 

Center of three spans that make up this river crossing. Spanning from Little Rock Island across Mississippi middle channel and across Willow Island to Cat Tail Slough public use area. All within Illinois. 1909 could be assumed as a build date but there is a row of piers along side this span to the south. So this could have been a second generation bridge.
