Bridge Documentation

This is an eight panel pin connected Pratt through truss. The bridge features a lattice portal bracing design. There is v-lacing present under the top chord, on the verticals, and the sway bracing. Pole railings, which appear to be original, are present on the bridge. There are attractive caps at the ends of the top chord on this bridge, which cover up the ends of the top chord, which does not merge into the end post like most truss bridges. The first section of sway bracing at either end of the bridge appears to have been replaced. The deck present on the bridge is wood with an asphalt wearing surface. There is a steel stringer approach span present at the southern end of the bridge.

There is a concrete pier in the middle of the river, which this bridge does not rest on. This suggests that this single span bridge was relocated here long ago to replace a two-span bridge. Waterloo Heritage Bridge Inventory suggested a ca. 1910 construction date for this bridge. HistoricBridges.org suggests that this bridge may be much older. The reason for this is the non-standard detail where the ends of the top chord do not merge into the end post and instead terminate in a decorative casting.

This bridge and associated road have been abandoned. This raises many questions about the future of this bridge. Perhaps this bridge might eventually relocated to a park setting where the public can easily enjoy this beautiful structure.
