Today, I researched two bridges built by the King Iron Bridge and Manufacturing Company. This is one of them, and the Hale Bowstring Iron Bridge at Anamosa, IA is the other.

| HsitoricBridges Nathan rates this bridge with two 10s. "This is the oldest known surviving bascule bridge in the United States and the only known example in the country of a simple archaic draw bridge design. As a movable bridge it is truly tiny, and would have only allowed very small boats to pass. The creek it is located on is also very small. Bridges of this design are more common in Europe. The bridge was hand-operated and simple counterweighted chains would wrap around the counterweight sheaves to pull the bascule leaf up. In this manner it resembles a medieval castle drawbridge. The bascule leaf and the approach span has riveted connections, making it an extremely early surviving rivet-connected truss bridge in the United States. The bridge has been bypassed and preserved in place for pedestrians. The bridge retains good historic integrity considering its age, although some rivets on the trusses have been replaced with bolts. The rivets that survive have a primitve appearance to them indicative of the early use of rivets. Because of its rarity and age it is one of the most unique and important historic bridges in the state. The bridge is worthy of consideration of National Register National Significance." |
