Located in the town of Nashua, this large concrete arch bridge crosses the Cedar River near Greenwood Avenue,
Built in 1902, this structure features six large concrete arches, set onto concrete substructures. When built, this structure was very decorative, unusual for a functional railroad bridge.
In the record flooding of 2008, this bridge almost was removed to prevent a pooling of water upstream from it. However, it was later decided to leave the bridge intact.
After the flood, some work was done on the bridge to restore it and prevent further damage. Unfortunately, between 2008 and many other large floods, the decorative features have somewhat been destroyed.
Currently, the bridge is operated by Canadian National. No long term plans have been presented for the bridge, so it is assumed to be safe.
Overall, the bridge appears to be in good condition, a surprising shift from the damage seen by other bridges across the Cedar River.
