The bridge itself is entirely gone, leaving no trace above ground, yet its outline persists in the landscape through that field name and through a notation on Ordnance Survey maps that reads simply "site of". The gap between what the maps remember and what actually survives gives the place an oddly spectral quality.

Known as Rainbow Bridge, the structure was a notable piece of engineering for a footbridge. Its semicircular arch spanned 24 feet (7.3 metres) across the Inny, yet the deck was only a yard wide, and the whole thing rose to a considerable height above the river. Steps on both sides climbed to the level of the haunches, the lower curves of the arch where it begins to spring from its supports. It was narrow enough to seem improbable at that height, more like a raised causeway than a conventional bridge. In 1732, when the High Sheriff held court upon it, a contemporary writer noted it was in good repair. Within a generation, however, the arch had come down. The writer and physician Charles Smith recorded the collapse in 1756, and just two years later the traveller Richard Pococke, passing through the Iveragh Peninsula, confirmed that this "fine Bridge of one Arch" had lately been "suffer'd to go to decay". Whether it was ever furnished with parapets is uncertain; an illustration Smith made of it leaves the question open. The bridge stood roughly half a kilometre north-east of Dromod medieval church and about four kilometres upstream from the Inny estuary, close to where the Ahandrohid footbridge now crosses the same river.
