Stone Arch Bridge

Stone Arch Bridge is a railway viaduct with a slender stone arch that spans a waterway in Keene. The structure was built from locally quarried stone assembled using traditional masonry methods to form a durable arch.

The structure was built in 1847 and has shaped New Hampshire's rail network ever since. It stands on the National Register of Historic Places as an important example of the state's mid-1800s transportation infrastructure.

The bridge showcases the craftsmanship of the 1800s through its carefully laid stones that visitors can examine up close. The structure tells the story of when such works were built entirely by hand to last for generations.

The structure is easily accessible from the waterway's edge and visible from multiple angles. Visitors should wear sturdy shoes since the surrounding ground can be uneven and the stone may become slippery.

The structure has kept its original stone composition since its construction, demonstrating the lasting quality of 1800s building methods. Some stones still bear the marks of hand-tooling, revealing the skilled labor involved in its creation.
