Notes
  • Significance: The Cottonville Bridge is among Iowa's earliest extant examples of welded bridge construction. It is a simply supported, single-span tied arch structure that combines elements that are both anachronistic and innovative. Its arched configuration resembles an updated version of the venerable bowstring arch-truss built widely on Iowa's roads in the 1870s and 1880s. Its extensive use of welded connections at a time in which welded technology was in its formative stages, however, marks the bridge as a sophisticated design exercise.
