[1] The Foundry Bridge is located in the village of North Tunbridge, providing access across the First Branch White River to rural eastern parts of the town via Foundry Road.

The bridge is a single-span Warren pony truss, set on abutments of dry laid stone.

The bridge is trapezoidal in profile, its trusses 72 feet 6 inches (22.10 m) in length.

The web of truss components reflects a means of fabrication that was obsolete at the time, but still in use by the builder, who had not yet adopted recent advances in steel rolling technology.

The bridge, built for the town at a cost of $876, provided access from the village of North Tunbridge to two of its major industries, Smith's Foundry (for which the road is named) and a gristmill.
