Iowa has one of the largest and richest collection of historic bridges in the country, and has traditionally had the most historic bowstring truss bridges, while also having numerous metal truss bridges of all kinds. Winneshiek County has traditionally been one of the top counties in the state, however since 2010 all preservation efforts appear to have ceased and the county has begun to demolish many bridges including nationally significant historic bridges. Although Iowa in general does not demolish as many historic bridges as many states, and many bridges have also been preserved, more historic bridges are destroyed by flooding in Iowa than any other state. Preservation of Iowa's bridges must include careful flood analysis and often preservation of its bridges may include placing them on the ground as a non-functional exhibit to save them from unstable substructures.
