Aber-Ogwen Iron Bridge

On the Penrhyn Castle estate, east of Bangor, Gwynedd

See Geograph entry and Coflein entry.
Now open as a section of the Wales Coast Path.[1]
Each of the three arch ribs appears to be assembled from just two main castings, joined at mid span, with the addition of a minimal number of cross braces. The ligaments of the rib castings are of substantial section. The foundry moulding appears to be of high standard. A few bolted repairs are evident.
