A rigid-frame bridge is a load resistant skeleton constructed with straight or curved members. It is a simple structure with top and sides of one solid piece of reinforced concrete. This design was especially popular during the 1920s. It is specially designed to resist bending, shearing, and axis loads. This type of bridge was cheaper to construct and easier to maintain and stronger than traditional bridges for its day. Wilbur Wilson, a professor of Civil Engineering and researcher of the fatigue of structures at the University of Illinois was a tremendous advocate of this type of structure. One of Wilson’s most notable discoveries was that bolts would be better to use than rivets in a rigid-frame bridge.
