County engineers public meeting on 11/19/2019 at the Dunkerton City Library at 6pm to discuss options for this bridge. Options listed in the letter are 1. Do nothing and leave bridge as is. 2 Construct a new bridge.3 Remove existing bridge without replacement. Nothing said about repairing the existing structure.

Here is a classic example of a great truss bridge being put in danger by a failing substructure. This happens all too often across the country, and there are multiple reasons why it can happen.

Portals and portal bracing suggest ca.1900

Well, with lally columns and pin connections I seriously doubt this bridge was manufactured in 1945, or even installed here in 1945. I say much older, pre-1920.
