The Eveland Bridge is a rare example of a multiple-span Whipple truss bridge. A less common variation on the Pratt truss, the Whipple truss was seldom used for wagon trusses in Iowa, and only seven remain today. Spanning the Des Moines River, the Eveland Bridge was the primary connection for southwest Mahaska County and played a major role in county commerce for decades after its erection.
