Farmleigh Bridge, Victorian bridge in Strawberry Beds, Dublin, Ireland

Farmleigh Bridge is a single-span cast iron box truss bridge about 52 m long, crossing the River Liffey and the Lower Lucan Road. It rests on two stone and masonry supports faced with cut limestone blocks, embellished with buttresses and round-headed arches. The bridge has ornate gates at either end and a masonry portal on the north side.

The bridge was constructed in the 1870s by Edward Cecil Guinness, replacing a ferry that previously transported people across the river. It was originally built to carry water pipes and later electricity lines from a mill turbine to other locations.

The bridge once served as a symbol of industrial progress along the Liffey Valley and reflects how private enterprise shaped Dublin's infrastructure. It shows the influence that wealthy families held in transforming the city during the 1800s.

The bridge is currently not open to visitors as it remains under preservation work. Stone gateways mark the entrance but there is no functioning pedestrian pathway across the structure.

The bridge carried water pipes and electricity lines from a mill race turbine to Farmleigh House and its clock tower, which held a large water tank. A deck over the pipes and cables let the Guinness family and staff cross on foot, and staff living south of the river at Palmerstown used it as a shortcut to the house.
