Seán Heuston Bridge (Irish: Droichead Seán Heuston)[2] is a cast-iron bridge spanning the River Liffey beside Heuston Station, Dublin.[3] 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.
