This large and unique bridge crosses the Maple River just south of Good Thunder, and has been preserved by a very generous landowner!
The bridge here was built in approximately 1930, to replace an 1882 truss which was relocated from the first bridge at Byron, Illinois in approximately 1905.
This span is believed to have been part of the second Byron Bridge, which existed from 1897 until 1929. Because of the large skew of that span, the Milwaukee Road reused older spans across the system to replace other skewed wooden bridges.
Despite its abandoned state, the bridge is well maintained for hunting and walking by the landowner. The landowner had mentioned interest of rehabilitating and restoring the bridge. For a unique and beautiful structure, this is absolutely worth it!
In a technical sense, the bridge is also an uncommon design. The bridge contains a 45 degree skew, and an 8-Panel Pratt Through Truss with pinned connections. This truss contains a single vertical endpost on each end, adding to the unique design. It appears that one panel was removed, giving a total span length of 139 feet 6 inches.
The approaches are constructed of wood, as are the piers. Overall, it appears to be in very good condition for the age.

Byron, Illinois bridge; This bridge was one of the five spans shown. Note the vertical endpost of the three middle spans.
The author has ranked this bridge regionally significant on a number of factors. The bridge retains an excellent and exceptional level of historic integrity. Preservation of this structure also adds to the significance, as well as the unique design.
