Evaluating fire-damaged components of historic covered bridges

The Cedar Covered Bridge, Winterset, Iowa, was destroyed by a fire set by an unknown arsonist on the evening of September 3, 2002. The Madison County Board of Supervisors constructed a replica of the original bridge, but this replica was also destroyed by an arsonist on April 15, 2017.

Snapshot: Arson continues to claim many historic covered bridges including the most recent one: Cedar Covered Bridge
Summary:

Site-specific, post-fire evaluations of the structural integrity of a bridge are often necessary in a fire's aftermath. Decisions on whether individual wood components can be rehabilitated, reconstructed, or replaced must be made. This report includes coverage of existing approaches and exploratory approaches that can be used for general guidance and a select number of more specific treatments that can be used to approximate the residual capacity of individual fire-damaged members. Topics such as fire-retardant treatments and other measures to prevent future fire damage are also discussed.
