Located near the town od Dahinda, this massive truss bridge crosses the Spoon River.
Built in 1910 to replace an older single track bridge, this structure features a massive 9-panel pin connected Parker Through Truss. In addition, it is approached by a pair of through girders on either side. The entire bridge sits on concrete substructures.
The truss of this bridge is rather unique. Railroads had mainly stopped using pin connected trusses by 1910. However, the long length of this span required a Parker design with pin connections.
In addition, the through girder approaches are 105 feet long each, unsually long for the time period.
Unfortunately, BNSF has recently been upgrading trusses along this route.
Overall, the bridge appears to be in good condition. The future is uncertain for this bridge, due to the large amount of traffic it carries.

The author has ranked this bridge as being regionally significant, due to the unusual truss design.
