Of the nine truss spans, five of them are over flood plains.

It is good to see that Illinois is doing at least some maintenance on a truss bridge.
But maintenance expenditures will be stranded assets. IDOT completed a 3-year environmental impact study and plans on replacing this bridge with a UCEB (Ugly Concrete Eyesore Bridge) 300' south of this bridge in their FY21-26 funding cycle. IDOT says it will look similar to the Champ Clark Bridge
. The Clark Bridge is just two lanes, but it does have wide shoulders. It will not only be high enough that it doesn't need a moveable span, it will be designed to more effectively avoid flooding. [wlds
Florence is not much more than a grain elevator. There is a stone quarry
just a little north of this road.
Ed & Woodie's Tap is now permanently closed. This is another reminder that 2019 was a very wet year in the heart of the USA. However, it does appear to have opened again as the Riverbank
. If the water was this far inland, it must have been real close to the bottom of the trusses.
And the flood plain extends beyond the truss spans that were built over land.

Taking another look at a satellite image, the above view is of the east side and the hill in the foreground is a levee.
"The Florence bridge was refurbished in 1981, and refurbished again in 2004. In the 2004 project, the deck was replaced, the bridge was sandblasted and painted, the lift cables were replaced, a new operators house was built, and electrical work was performed. Update—the Florence Bridge was closed on June 28, 2012, when a routine inspection revealed a structural issue at the top of one of the lift towers. This caused one set of large pulleys at the top of the bridge to shift laterally. If the bridge were to remain in operation, additional damage would occur that would be much more difficult to repair. The bridge is expected to be closed at least 9 months while a repair strategy is developed. In the mean time, the lift span has been left in the open position to allow river navigation traffic to pass under the structure."
