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.

Fair enough, if you prefer that entries exist for both names of the bridge, the broken link (under Sources for the Eureka bridge) should be fixed so that someone searching for either name doesn't miss the information posted under the alternate name.

This entry was made before the original location of the bridge was known by us bridgehunters.

A bridge so nice, it's been listed twice. (under it's two common names)



Perhaps these pages should be merged. I vote for the resulting page to be listed as moneek.
