Huddlestone Arch

In the quiet green wilderness of the North Woods is a marvel of engineering: Huddlestone Arch.

Made entirely of enormous, uncut boulders weighing up to 100 tons, the stone arch uses only physics—no binding materials like mortar—to keep the bridge in place. The key to the engineering of Huddlestone Arch is in gravity and pressure, proven powerful forces. The resulting arch is so sturdy that it supports traffic traveling over the Loch on the East Drive.
