Road bridge and screen, Ballywalter Park, Springvale, Ballywalter, Newtownards, Co. Down, BT22 2PP

A picturesque sandstone bridge and an accompanying screen were built around 1850 by the notable architect Charles Lanyon, as part of Ballywalter Park. The bridge spans a stream along the main drive within the park and is oriented obliquely to the stream’s flow. The segmental arch, approximately 1.5 meters wide, features vermiculated voussoirs, while the base walls around the arch are constructed from snecked rubble. Sturdy, panelled end piers have vermiculated quoin bases and a cornice that runs over the arch's crown. A balustrade serves as the parapet, with decorative balusters between the end piers and a central pier. The central piers display shell motifs on both their inner and outer faces, and the end piers have blocking stones above the cornice. Approximately 45 meters northeast of the bridge stands a similar arched screen, marking the point where the stream flows underground. Both the bridge and screen are based on the designs of two bridges previously constructed on the western side of the estate. Both structures are partially covered in ivy.

The bridge and screen are virtual replicas of the bridges on the estate’s western side and were likely constructed around the 1850s, coinciding with Charles Lanyon's extension and remodelling of the main house for the estate’s new owner, Andrew Mulholland. The listing includes both the bridge and the screen walls. The screen was formerly a separate listed structure (HB24/04/098).
