Old Stone Arch Bridge

The Old Stone Arch Bridge spans Jack's Creek with a single arch made entirely of stone, built without using a keystone in its construction. The structure sits within a landscaped park area that offers benches and pathways for visitors to walk around and view the bridge from different angles.

Philip Diehl constructed this bridge in 1813 as part of the Harrisburg to Pittsburgh Turnpike, a major transportation route of that era. It stands as one of the oldest surviving bridges from this period when roads and passages were being established across Pennsylvania.

The bridge showcases early American engineering methods and reflects how transportation shaped settlement patterns in Pennsylvania. Visitors can observe the stone construction techniques that were common when this area was developing and connecting to distant regions.

The bridge is accessible via the park area which has benches and walking paths around the structure for easy exploration. Comfortable shoes are recommended if you want to walk around and view the bridge from multiple vantage points.

The bridge was built without a keystone, an unusual design choice that sets it apart from typical arch bridges of its time. This construction method reflects how engineers experimented with different approaches to creating stable crossings over waterways.
