Summary

Significance: The Rock Island Bridge was constructed in 1895-1896 to connect the arsenal with Davenport, Iowa. It was the first major bridge commission of Chicago engineer Ralph Modjeski, who subsequently established a reputation as one of the country's leading bridge designers. The bridge was equipped with a variety of innovative safety features, including pneumatic rail locks, which did not become widely used until two decades later. Part of the Rock Island Arsenal National Register Historic District, the Rock Island Bridge is the oldest surviving Mississippi railroad crossing in the Iowa-Illinois region.
