Seán Heuston Bridge is a cast-iron bridge spanning the River Liffey beside Heuston Station, Dublin. It was previously named King's Bridge and Sarsfield Bridge - and the bridge and adjacent train station are still commonly referred to by older Dubliners as "Kings Bridge" and "Kings Bridge Station" respectively. Previously used for road traffic, the bridge now carries pedestrian and Luas (tram) traffic.
Originally designed by George Papworth to carry horsedrawn traffic, the foundation stone was laid in 1827. Construction completed in 1828, and the bridge was opened with the name Kings Bridge to commemorate a visit by King George IV in 1831.

The River Liffey flows through the centre of Dublin. Its major tributaries include the River Dodder, the River Poddle and the River Camac. The river supplies much of Dublin's water and a range of recreational activities. It rises in The Wicklow Mountains and flows 125km.
