CP/Milw Bridge over Rock River at Byron, IL

(1882 Bridge Hunter; 1897 Bridge Hunter; 1905+? Bridge Hunter; no Historic Bridges; Satellite, you can see that the piers for probably the 1897 bridge are still standing.)

These twin spans are a puzzle. Since the southern one is pin connected, it is older than the northern one. But the concrete pier on the south is more modern than the cut stone part on the north. However, the northern one is upstream so it gets the brunt of the ice flows. Maybe scouring is what caused the southern part of the piers to require concrete repairs.
