This unique swing bridge crosses the Root River in downtown Racine.
The bridge consists of a large Double Intersection Warren Deck Truss, which rests on a round pier. This span is made as a swing span.
This main span is a center pivot span, meaning it is a continuous span. These types of spans are rare, particularly after the 1880s.
This is because they are difficult to engineer. One miscalculation could lead to an entire span falling off the pier.
Previous Bridge
The main truss has riveted connections. This span is set onto a stone pier.
In addition, the bridge is approached by deck girder spans on either side. These are also set onto stone substructures.
In terms of operation, the main swing span appears to retain the ability to move if necessary, with all the gears intact. However, the ends have been replaced with a stationary type of bridge shoe. Despite this, this is a significant boost in terms of historical integrity.
The author has ranked this bridge as being moderately significant, due to the uncommon design demonstrated by the structure. The bridge also retains a great amount of historical integrity and is in great condition.
