Not the bridge itself, but its ghost, preserved in the bureaucratic language of a 1991 planning document as though the absence of a structure is itself worth marking on a map.

The reference appears in the Dublin City Development Plan of 1991, listed as entry number 15, which designates the location on Bonham Street North as the "site of Bridge". The citation traces back to Bradley and King's 1987 survey, suggesting that by the late twentieth century the bridge had already disappeared from the physical landscape entirely, surviving only as a cartographic notation. The area around Bonham Street sits in the Liberties, one of the oldest settled parts of Dublin, where medieval lanes, industrial-era laneways, and Victorian tenement streets have layered over one another for centuries. A bridge in this district would most likely have crossed one of the city's smaller watercourses, many of which were culverted or built over as Dublin expanded and its open channels became inconvenient to an industrialising city.

There is little to see at the site today in any conventional sense. Bonham Street itself is a modest residential road, and nothing announces the former crossing. For those interested in Dublin's lost waterways and the slow erasure of its pre-industrial topography, the spot rewards a short detour. The value here is less visual than conceptual: standing at a location that appears in planning records specifically because something has gone, one gets a small but precise sense of how cities document their own forgetting. The 1991 plan is held in Dublin City Council archives, and Bradley and King's 1987 work on Dublin's historic infrastructure remains a useful guide for anyone tracing the city's older layers on foot.
