Back in 2006, when HistoricBridges.org documented Iroquois County, the following statement was placed into the narrative: "Iroquois County is filled with a large number of remaining truss bridges, must most are no larger than 100 feet in length, and many are short pony trusses." As of 2013, this statement is no longer accurate. Iroquois County has demolished a large number of its truss bridges and only a small number remain. In 2006, this bridge, a pin-connected Pratt through truss with a relatively long 143 foot span. At the time, it was the longest of a number of through truss bridges in the county. Today, it appears that this is the only through truss of any size in the entire county!
The demolition of Iroquois County's bridges since the turn of the 21st Century has been so widespread and unrelenting that it is enough to reduce any bridge historian to tears. A county that had an amazingly large and complete collection of historic bridges has nearly annihilated that collection. As such, this bridge is likely at risk for demolition as well. However, HistoricBridges.org urges Iroquois County to rehabilitate this bridge instead, something that likely costs less than it would to replace the bridge. This would at least ensure that the county does not lose everything and would prevent Iroquois County from becoming a county that does not have a single through truss remaining.
The bridge is an eight panel structure, and is does not fall into the pattern of similar design as other Iroquois County truss bridges did. The portal bracing is a large lattice design, while the sway bracing also employ an even larger and simpler lattice design. There is v-lacing on the verticals and under the top chord and end posts. The base of the deck is concrete. The abutments are also concrete.
