Significance: The wrought-iron Eureka Bridge is an example of the bowstring bridge, called bowstring truss or iron arch in the nineteenth century. Bowstring bridges were widely built in Iowa in the period 1860-1880. As with other iron bridges, they were usually produced in the shops of large bridge companies. The Eureka Bridge represents the small minority of such bridges designed and built by local entrepreneurs in regional machine shops.
