The 'Metal Bridge' is a unique suspension bridge, the only surviving example in Northern Ireland of a 19th Century wrought and cast-iron suspension-type footbridge, it spans the River Blackwater. It is unique in that the number of iron rods progressively diminishes towards the center of the bridge. The bridge was dismantled, refurbished and re-erected in its present location on the same river. The cache is a tablock box, 120mm in diameter, camo'd containing logbook, pencil and room for swappables. Parking is by the main road close to the bridge.
