This is one of the only known surviving examples of a bridge using the patented Kahn type of trussed rebar. Visit the South Bridge's page to learn more about Kahn reinforcing.
The bridge appears to have been extensively rehabilitated, and the spandrel walls may have been replaced. The arch ribs which contain the patented Kahn reinforcing appear to be original however.
Architecturally, the bridge is also noted for its graceful flowing arch shape especially at the pier, a design that is surprisingly modern looking given that it is a relatively early concrete arch bridge.
