IANR - Mud Creek Bridge

The pier of the bridge makes me think that this bridge was assembled using at least one relocated piece. This historic aerial image shows a much smaller bridge here:

During the 1940s, the Rock Island was upgrading many bridges on mainlines, and relocating the old spans to less used routes.
