Bridge Documentation

View Archived National Bridge Inventory Report - Has Additional Details and Evaluation

This bridge is a representative example of a riveted Parker truss bridge in Iowa built to a standard plan. The bridge contains an eight panel Parker truss, and two steel stringer approach spans. The bridge is traditionally composed, and retains good historic integrity. The end post of this bridge has a line painted indicating a high 1944 flood level at the bridge, which was just above the railings.
