Rathdrum Bridge is a historic bridge spanning the Avoca River. Rathdrum itself was an important town during the 18th and 19th centuries, serving as a vital link for trade and transportation. The Avoca River was crucial for the local economy, particularly in relation to the Avoca mines and the surrounding agricultural community. The bridge likely dates back to the 19th century and was a critical structure for connecting the town to the rural areas of County Wicklow.
