This is Seán Heuston bridge beside Heuston Railway station. It's a wonderful cast-iron bridge which was built in the early 1800's and is now used only as the Luas right rail crossing of the river Liffey and as a pedestrian crossing. All other traffic was moved to the new Frank Sherwin Bridge which was built in 1982. The tide actually comes this far up-river and you can see from my photo that the tide is out and that there is a lot of rubbish lying on the riverbed. You can also see a lot of moss and vegetation growing on the river wall beside the station. Heuston Station looks very well nowadays after a welcome bit of investment in recent years, pity somebody wouldn't organize a clean-up of the adjacent river!
