What makes this bridge special?
The Bridge in Porter Township is special because of its unique design. It uses a lenticular truss system, which looks a bit like a lens or an eye shape. This design was popular for a short time in the late 1800s. Not many bridges like this are still around today.
Because of its age and special design, the bridge was added to the National Register of Historic Places in 1988. This is a list of important places in the United States that are worth protecting. Being on this list means the bridge is recognized for its historical and engineering importance.
What is a lenticular truss?
A truss is a framework, usually made of triangles, that helps a bridge hold up weight. A lenticular truss is unique because it has a curved shape both above and below the bridge deck. This creates a lens-like appearance.
This design was known for being very strong and efficient for its time. It allowed bridges to span long distances without needing many supports in the middle. The Porter Township Bridge is a great example of this clever engineering.
