The bridge served as a muster point for the Fingal Volunteers before they marched to the Battle of Ashbourne, a fight that took place away from the GPO and the street-by-street urban drama in Dublin city, out in the fields of north County Dublin.

The bridge itself dates to around 1800, built from coursed rubble limestone with large, roughly squared voussoirs, the wedge-shaped stones that lock an arch into place, and a projecting keystone finished with a simple hood moulding. Its single semi-circular arch carries the R108 over the Ward river, and the form of the crossing points to something older beneath its current fabric. John Rocque's map of 1760 shows a crossing at this location, though it is left unnamed, suggesting a ford or earlier bridge served travellers here well before the present structure was raised. That layering of crossings, one generation of infrastructure quietly succeeding another, is what makes the site read as more than a functional piece of Georgian road engineering.

The bridge sits on the R108 in Brackenstown, north of Swords. Approaching from either direction, the arch is visible where the road dips to meet the Ward river, and the commemorative plaque is set into the roadside face, readable without leaving the road. There is no formal car park or visitor arrangement; this is a working road bridge encountered in passing. The plaque rewards a moment's pause, particularly for anyone already tracing the route of the Fingal Volunteers or visiting Ashbourne itself, where the 1916 engagement took place some miles further north.
