To respond to John's old comment here, I STRONGLY agree that the bridge's truss spans, particularly the swing span with no "tower" at the center is most certainly older than 1913. The swing span, which lacks the "tower" at the center is reminiscent of extremely old swing trusses (1880s) although I have not yet visited this bridge (its on my list to visit) to try to confirm this, and current photos on the Internet do not provide the level of detail required. Evaluation of connection details, any iron/steel brands, etc would be potentially useful to try to date the spans. Given the scale of destruction that the 1913 flood caused it is not surprising at all that an old truss might have been moved here. There wouldn't have been enough fabricators in the world to replace all the bridges that were lost in that flood in the timeframe that everyone wanted their bridges fixed after that disaster, so creative solutions to reopen infrastructure were no doubt used.

Is this bridge older than 1913? The two center spans appear to be older, maybe ca. 1895? The swing span also appears to be a little newer, but not 1913. Reportedly, the stationary spans were replaced after the 1913 flood, but the swing span survived. The stationary spans very well could have been moved from another location.

Swing span is swung to prevent people from crossing the bridge. Fundraising effort is underway.
